Abstract

While the universal quantum computer seems not in reach for the near future, this work focusses on analog quantum simulation of intriguing quantum models of light-matter interactions, with the goal of achieving a computational speed-up as compared to classical hardware. Existing building blocks of quantum hardware are used from superconducting circuits, that have proven to be a very suitable experimental platform for the implementation of model Hamiltonians at a high degree of controllability.

Abstract

The topic of this publication is the design of two new set-based methods for the determination of the states of linear parameter-varying systems. These sets are computed by interval observers based on unknown but bounded inputs, outputs and parameters. The effectiveness of the methods is demonstrated by the state estimation of an induction motor that is achieved by combining the interval observers with a novel model of a voltage source inverter.

Abstract

We worked on different magnetic molecules containing 3d and 4f magnetic centers. Their growth on metallic surfaces, topographies, spin states, magnetic properties and electron transport were locally investigated by using scanning tunneling microscopy (STM) at temperatures down to 30mK. The main achievement of this dissertation reveals the abrupt switching of crystal fields during formation of molecular contacts.
