Probing the nodal structure of Landau level wave functions in real space
J. R. Bindel, J. Ulrich, M. Liebmann +1
The inversion layer of p-InSb(110) obtained by Cs adsorption of 1.8 % of a monolayer is used to probe the Landau level wave functions within smooth potential valleys by scanning tu…
Universal power-law decay of electron-electron interactions due to nonlinear screening in a Josephson junction array
Daniel Otten, Sebastian Rubbert, Jascha Ulrich +1
Josephson junctions are the most prominent nondissipative and at the same time nonlinear elements in superconducting circuits allowing Cooper pairs to tunnel coherently between two…
Dual approach to circuit quantization using loop charges
Jascha Ulrich, Fabian Hassler
The conventional approach to circuit quantization is based on node fluxes and traces the motion of node charges on the islands of the circuit. However, for some devices, the releva…
Probing variations of the Rashba spin-orbit coupling at the nanometer scale
Jan Raphael Bindel, Mike Pezzotta, Jascha Ulrich +3
The Rashba effect as an electrically tunable spin-orbit interaction is the base for a multitude of possible applications such as spin filters, spin transistors, and quantum computi…
Changing anyonic ground degeneracy with engineered gauge fields
Emilio Cobanera, Jascha Ulrich, Fabian Hassler
For systems of lattice anyons like Majorana and parafermions, the unconventional quantum statistics determines a set of global symmetries (e.g., fermion parity for Majoranas) admit…
Simulation of supersymmetric quantum mechanics in a Cooper-pair box shunted by a Josephson rhombus
Jascha Ulrich, Daniel Otten, Fabian Hassler
Supersymmetries in quantum mechanics offer a way to obtain degeneracies in the excitation spectrum which do not originate from selection rules. The mechanism behind the degeneracie…
Supersymmetry in the Majorana Cooper-Pair Box
Jascha Ulrich, Inanc Adagideli, Dirk Schuricht +1
Over the years, supersymmetric quantum mechanics has evolved from a toy model of high energy physics to a field of its own. Although various examples of supersymmetric quantum mech…
Thermal conductance as a probe of the non-local order parameter for a topological superconductor with gauge fluctuations
B. van Heck, E. Cobanera, J. Ulrich +1
We investigate the effect of quantum phase slips on a helical quantum wire coupled to a superconductor by proximity. The effective low-energy description of the wire is that of a M…
Spectral Properties and Local Density of States of Disordered Quantum Hall Systems with Rashba Spin-Orbit Coupling
Daniel Hernangomez-Perez, Jascha Ulrich, Serge Florens +1
We theoretically investigate the spectral properties and the spatial dependence of the local density of states (LDoS) in disordered two-dimensional electron gases (2DEG) in the qua…
