Periodic orbit theory of Bethe-integrable quantum systems: an -particle Berry-Tabor trace formula
Juan Diego Urbina, Michael Kelly, Klaus Richter
One of the fundamental results of semiclassical theory is the existence of trace formulae showing how spectra of quantum mechanical systems emerge from massive interference among a…
Dirac Landau levels for surfaces with constant negative curvature
Maximilian Fürst, Denis Kochan, Ioachim-Gheorghe Dusa +2
Studies of the formation of Landau levels based on the Schrödinger equation for electrons constrained to curved surfaces have a long history. These include as prime examples surfac…
Controlling quantum chaos: time-dependent kicked rotor
Steven Tomsovic, Juan Diego Urbina, Klaus Richter
One major objective of controlling classical chaotic dynamical systems is exploiting the system's extreme sensitivity to initial conditions in order to arrive at a predetermined ta…
Dynamical transition from localized to uniform scrambling in locally hyperbolic systems
Mathias Steinhuber, Peter Schlagheck, Juan-Diego Urbina +1
Fast scrambling of quantum correlations, reflected by the exponential growth of Out-of-Time-Order Correlators (OTOCs) on short pre-Ehrenfest time scales, is commonly considered as…
Controlling Quantum Chaos: Optimal Coherent Targeting
Steven Tomsovic, Juan Diego Urbina, Klaus Richter
One of the principal goals of controlling classical chaotic dynamical systems is known as targeting, which is the very weakly perturbative process of using the system's extreme sen…
Supercurrent interference in HgTe Josephson junctions
Wolfgang Himmler, Ralf Fischer, Michael Barth +8
Wires made of topological insulators (TI) are a promising platform for searching for Majorana bound states. These states can be probed by analyzing the fractional ac Josephson effe…
