(c) Uni Basel Hier sehen Sie eine Abbildung von magnetischen Flusslinien an der Oberfläche eines Hochtemperatur-Supraleiters. Dieses Bild entstand während meiner 1995 abgeschlossenen Dissertation, die ich im Rahmen eines grösseren Forschungsprojektes an der Uni Basel erstellt habe. Meine Aufgabe lag in der theoretischen Beschreibung der Wechselwirkung zwischen magnetischen Flusslinien und kleinen magnetischen Partikeln, die als Sensor eines Magnetkraftmikroskops eingesetzt werden. Genaueres zu diesem Themenbereich können Sie einer ausführlichen theoretischen Publikation (Artikel) entnehmen oder einem der weiteren unten angegebenen Artikel.

Meine Post-Doc-Zeit bestand aus Aufenthalten am Rutherford Appleton Laboratory bei Oxford (GB) und, ab März 1998, am Paul Scherrer Institut (Villigen, Schweiz). An beiden Orten widmete ich mich weiterhin der Physik der kondensierten Materie. Dabei interessierte ich mich besonders für die statischen und dynamischen Eigenschaften von ungewöhnlichen und niedrig-dimensionalen magnetischen Systemen und das Studium entsprechender Materialien mittels Neutronen- und Röntgenstreuung. Ich befasste mich u.A. mit elementaren Anregungen in alternierenden Spin-Ketten und -Leitern sowie den magnetischen Eigenschaften der Seltenen Erden. Die an diesen Materialien gemachten experimentellen Beobachtungen sind klare Manifestationen quantenmechanischer Vielteilchenprozesse, und das Verständnis ihrer mikroskopischen Ursachen und Zusammenhänge stellt derzeit eine grosse Herausforderung der Theoretischen Physik dar.

Seit Februar 1999 arbeite ich bei ABB. Meine Tätigkeit begann zunächst im Forschungszentrum in Baden (Schweiz). Dort leite ich die Theoretical Physics Group und befasse mich mit unterschiedlichen Fragestellungen aus der Physik und der Informationstechnologie. Mein besonderes Interesse galt dabei neuen Konzepten der dezentralen Energieversorgung. Später entstanden in Zusammenarbeit mit dem IBM-Forschungszentrum Rüschlikon einite Arbeiten zur Molekulardynamik in Gleichspannungs-Isolationswerkstoffen. Seit Ende 2014 leite ich nun die Entwicklung im Bereich Control and Monitoring for High-Voltage Products in Zürich. Hier beschäftige ich mich insbesondere mit der Digitalisierung diverser Sensortechnologien und Datenverarbeitungsprozesse. Seit dem 1. Juli 2020 bin ich zusätzlich für Forschung und Entwicklung im Bereich Generatorschalter zuständig. Ausserdem heisst mein Arbeitgeber seither Hitachi Energy.

The picture above shows the first successful magnetic force microscope measurement of magnetic flux lines near the surface of a high-temperature superconductor. It has been taken towards the end of my thesis at the University of Basel, where I was involved with research on the interactions between magnetic flux lines and small magnetic particles, which are used as sensor tips of magnetic force microscopes. A detailed theoretical article on the subject (paper) as well as references to publications on the experiments can be found on the list below.

My post-doc time consisted in a stay at the Rutherford Appleton Laboratory near Oxford (UK), and in being a member of the Condensed Matter Theory group at Paul Scherrer Institut (Villigen, Switzerland). At both places I was especially interested in the static and dynamic properties of unconventional and low-dimensional magnetic systems and the investigation of related materials by neutron and x-ray scattering techniques. I was concerned, e.g., with low-lying excitations in alternating spin chains and ladders, or with the magnetic properties of rare-earth ions. In these materials quantum-mechanical many body theory manifests itself in an amazing range of experimental observations. Their understanding and description remains a great theoretical challenge.

Since February 1999 I have been working for ABB. My career started at Corporate Research in Baden (Switzerland). As head of the Theoretical Physics Group I was concerned with a variety of problems from the field of physics and information technology. My special interest lied in new concepts of decentralised power generation and distribution. Later, I was concerned with molecular dynamics in DC insulation material, which led to a number of publications together with colleagues from IBM Research in Rüschlikon. Since November 2014 I have been heading the development of control and monitoring applications for high-voltage products. My contributions are particularly focussed on digitalization of various sensing and data transmission technologies. Since 1st July 2020, I am additionally responsible for managing research and development for Generator Circuit Breakers. On the same day, my employer changed its name to Hitachi Energy.

Abstract. In the present work we calculate the magnetic field above a type II superconductor containing a single isolated flux line. Using an anisotropic Ginzburg-Landau theory and a Euler-Lagrange-like variational procedure we estimate the influence of a surface perpendicular to the flux line on its magnetic and electronic structure. Additionally, we calculate the dependence of the strength of this influence on the anisotropy of the system and on its Ginzburg-Landau parameter. Highly anisotropic superconductors show a considerable widening of the electronic core radius of a flux line directed along the c-axis towards a surface.

Stephen W. Lovesey, Oliver Fritz, and Ewald Balcar. A theory of magnetic x-ray diffraction enhanced by an electric quadrupole (E2) resonance. J. Phys.: Condens. Matter 10, 501 (1998).

Abstract. The electric quadrupole contribution to the scattering length is derived using an atomic model for the resonant ion. At one of the levels of approximation considered, our so-called idealized scattering length is totally consistent with the standard sum rules for the analysis of the attenuation coefficient. A superior estimate of the scattering length includes the structure of the core state. The two levels of treatment are used to discuss the intensity of x-rays Bragg diffracted by resonant lanthanide ions in a crystal. Using a ground state for the valence shell specified by Hund's rules, explicit expressions for the idealized scattering length are tabulated for the tripositive ions. The general expressions for the scattering length can be evaluated for a valence-shell wave function of an arbitrary complexity. Thus, our scattering lengths can accommodate the influence of a crystal-field potential or a full multiplet calculation. Linear and circular polarization in the primary and secondary beams of x-rays are handled in terms of a Stokes vector, and several illustrative calculations are given.

Oliver Fritz, Stephen W. Lovesey, and Greg I. Watson. Static and dynamic properties of a dimerized quantum-spin chain. J. Phys.: Condens. Matter 10, 6321 (1998).

Abstract. Various static spin-correlation functions and the weights of the spin excitations, or collective normal modes, in the van Hove response function, observed in neutron scattering experiments, are calculated as a function of temperature for a model quantum-spin chain. The spins interact through an isotropic Heisenberg exchange that extends to nearest-neighbour spins. In our model, spins of magnitude 1/2 form a dimerized chain with alternating exchange interactions. We explore the static and dynamic properties for ferromagnetic and antiferromagnetic exchange interactions. Results for the various properties are shown to be exact in the limit of a high temperature, and we argue that the results are very good at low temperatures. Unlike the case for linear spin-wave theory, the results are also exact in the limit of strong dimerization, i.e. non-interacting coupled pairs of spins.

Oliver Fritz and Petter Skerfving. Monitoring and Analysis of Power Line Failures: An Example of the Role of GIS. In J. Pick (ed.), GIS in Business. Hershey: Idea Group Publishing (2004).

Abstract. This chapter presents a case study on the role of Geographical Information Systems in power utility automation. It argues that Geographical Information Systems are ideal software components for enterprise-wide application integration, data and asset management, and decision support applications. The authors believe that advances in industrial software applications are predominantly realized through stepwise integration and extension of existing systems. A case study on a monitoring application for power lines serves as example for this thesis. Furthermore, the authors hope that understanding technical and economical conditions governing the field of industrial automation helps readers in appreciating that software development and integration strategies are strongly linked to organizational and structural changes in the power utility industry.

Abstract. The authors describe a performance-evaluation tool for Generator Circuit Breakers (GCB) that assists in the process of selecting the right model and specifications from a number of customer requirements. The tool is based on a thermal-network library implemented in Modelica. A wrapper application based on Excel and .NET technology serves as user interface and driving application for the necessary simulations.

T. Delachaux, O. Fritz, D. Gentsch, E. Schade, D.L. Shmelev. Numerical simulation of a moving high-current vacuum arc driven by a transverse magnetic field. ISDEIV, Matsue (2006).

Abstract. The present modeling deals with the physical description of the high-current (>10 kA) constricted vacuum arc, driven by a transverse magnetic field (TMF), as found in vacuum circuit breakers applying TMF arc control. The MHD approach together with detailed heat transfer and evaporation equations for the electrodes are used to describe the arc behavior selfconsistently, restricting to two dimensions (2D). A newly developed model describes the cathode attachment of the constricted arc in form of a large laterally extended foot point, instead of the regular cathode spots. This model leads to the characterization of the physical quantities of the arc plasma and describes the arc motion as step-wise due to the different velocities of the current attachment areas of cathode and anode.

B. Singh, O. Fritz, A. Simperler, C. Menke. Quantum Mechanical Simulations and Experimental Evaluations of the Catalysis Reaction of the Reactions of Epoxy Resins with 1-Imidazole and 1-Dimethylbenzylamine. International Journal for Multiscale Computational Engineering, 7(5), 409-417 (2009).

Abstract. In this article, the rate of epoxy curing with two different accelerators, i.e., 1-imidazole (MI) and 1-dimethylbenzylamine (DMBA), is experimentally investigated. It has been found that the rate of MI-cured epoxy is higher than that of its DMBA-cured counterpart. Moreover, it has been observed that the Tg of MI-cured epoxy was higher than that of DMBA-cured epoxy. To understand this phenomenon, a quantum mechanical density functional theory code (DMol3) was used to simulate the epoxy reaction using these accelerator molecules to study their effectiveness. This was carried out by analyzing the heights of energy barriers of different polymeric reaction steps and studying the geometry of transition states. From the simulations, it was established that the DMBA epoxy is slower because of its geometric steric hindrance and higher energy of the barrier at the initiation, propagation, and termination steps.

Abstract. In this paper, we have studied silicone polymers based on poly(dimethylsiloxane) (PDMS) molecules, which have versatile applications in many fields because of their flexible molecular properties. These polymers are of interest because when used for high-voltage insulation, surfaces exposed to weather need to be hydrophobic because a hydrophilic surface can cause leakage currents. Indeed, after damaging electrical discharges, self-recovery of the hydrophobic surface occurs, requiring molecular diffusion and surface reconstruction for repair. We use large-scale, all-atom molecular dynamics simulations that enable an atomic-level description of molecular motion in mixed, amorphous, PDMS-based materials. The local properties that contribute to enhanced molecular motion are characterized based on their local structural and electrostatic environment. With this knowledge, molecular components with desirable diffusion properties may be designed for improved material functionality.

Abstract. Amorphous siloxane polymers are the backbone of high-voltage insulation materials. The natural hydrophobicity of their surface is a necessary property for avoiding leakage currents and dielectric breakdown. As these surfaces are exposed to the environment, electrical discharges or strong mechanical impact can temporarily destroy their water-repellent properties. After such events, however, a self-healing process sets in and restores the original hydrophobicity within some hours. In the present study we investigate possible mechanisms of this restoration process. Using large-scale, all-atom molecular dynamics simulations, we show that molecules on the material surface have augmented motion that allows them to rearrange with a net polarization. The overall surface region has a net orientation that contributes to hydrophobicity, and charged groups that are placed at the surface migrate inward, away from the vacuum interface and into the bulk-like region. Our simulations provide insight into the mechanisms for hydrophobic self-recovery that repair material strength and functionality, and suggest material compositions for future high-voltage insulators.

Abstract. Amorphous siloxane polymers are designed to have high dielectric strength for use as high-voltage insulation materials. Surface hydrophobicity is essential and can be impaired by environmental, electrical, or mechanical factors, leading to leakage currents due to dielectric breakdown. Self-recovery is possible and is generally observed over a period of several hours. Using large-scale, all-atom molecular dynamics simulations, the surface wetting of water droplets on the polymer surface is simulated for various surface conditions, including oxidation and coating with small molecules, to understand the driving forces of the recovery process at the atomistic level, which is of primary importance for the developments of novel materials. In this work, we shed light onto the self-recovery mechanism and propose the use of low-molecular-weight (LMW) siloxane to accelerate the recovery of hydrophobicity.

Abstract. There is a general need of elaborating energy-effective solutions for managing our increasingly dense interconnected world. The problem should be tackled in multiple dimensions -technology, society, economics, law, regulations, and politics- at different temporal and spatial scales. Holistic approaches will enable technological solutions to be supported by socio-economic motivations, adequate incentive regulation to foster investment in green infrastructures coherently integrated with adequate energy provisioning schemes. In this article, an attempt is made to describe such multidisciplinary challenges with a coherent set of solutions to be identified to significantly impact the way our interconnected energy world is designed and operated.
