A large part of condensed matter physics concerns itself with understanding the behaviour of electrons in solids and finding ways to control them. However, in mesoscopic systems (i.e., systems with nanometer to micrometre scale), the behaviour of electrons is difficult to predict through the Schrödinger equation. Instead, it is often more...

The study of crystalline solids and condensed matter physics at large concerns itself with the new behaviors and phases of matter exhibited by elementary particles, atoms, and molecules by virtue of being assembled into a structure. These phases arise from complex microscopic behaviors, which makes it is difficult to establish rigorous...

Much of modernmesoscopic physics focuses on studying hybrid superconducting structures: systems that combine superconductors with other materials such as semiconductors, ferromagnets, and graphene. When properly engineered, these devices display emergent physical properties that are absent in their individual constituents. An early example of...

Modern materials synthesis techniques allowfor the layer-by-layer assimilation of structurally similar, yet compositionally different materials into artificial crystals, with atomic scale precision. At the resulting heterointerfaces, structural, electronic and magnetic reconstructions can lead to physical phenomena that are otherwise absent in...

Schmidt, F.E. (author)
This thesis investigates fundamental properties of Josephson junctions embedded in microwave circuits, and an application arising from this hybrid approach. We used the versatility of superconducting coplanar DC bias cavities to extract previously inaccessible information on phase coherent and subgap mechanisms of graphene Josephson junctions....

By exploiting quantum mechanics, quantum computers are able to solve problems---for example in quantum chemistry---that are far out of reach of classical computers. Conventional approaches to quantum computers use qubits (quantum bits) that can either be made out of superconducting circuits (the currently leading approach used to demonstrate...

Superconductor–semiconductor hybrid devices are interesting not only for their known and potential applications but also for the associated novel physical processes. One such example is the proposal for the realization of Majorana zero-modes, which are robust against noise and have applications in quantum information processing. Although the...

Nowadays, quantum computers, a promising direction of computer hardware development, suffer too much from errors caused by disturbance of qubits to compete with the state-of-the-art classical computers. Topological phases in condensed matter physics offer a solution: the topological edge states emerging in such a phase are spatially separated by...

Majorana bound states (MBS) have non-Abelian exchange statistics, which means exchanging the position of two MBS changes the state of the system. This attracted attention for multiple reasons: It is a quantum effect without a classical analogue, it introduces topology to condensed matter physics and the non-Abelian exchange processes allow...
