Nonexponential decoherence and momentum subdiffusion in a quantum Lévy kicked rotator
Henning Schomerus, Eric Lutz
We investigate decoherence in the quantum kicked rotator (modelling cold atoms in a pulsed optical field) subjected to noise with power-law tail waiting-time distributions of varia…
Effective contact model for transport through weakly-doped graphene
Henning Schomerus
Recent investigations address transport through ballistic charge-neutral graphene strips coupled to doped graphitic leads. This paper shows that identical transport properties aris…
Long-time signatures of short-time dynamics in decaying quantum-chaotic systems
T. Gorin, D. F. Martinez, H. Schomerus
We analyze the decay of classically chaotic quantum systems in the presence of fast ballistic escape routes on the Ehrenfest time scale. For a continuous excitation process, the fo…
Correcting ray optics at curved dielectric microresonator interfaces: Phase-space unification of Fresnel filtering and the Goos-Haenchen shift
Henning Schomerus, Martina Hentschel
We develop an amended ray optics description for reflection at the curved dielectric interfaces of optical microresonators which improves the agreement with wave optics by about on…
Non-universal suppression of the excitation gap in chaotic Andreev billiards: Superconducting terminals as sensitive probes for scarred states
Andor Kormanyos, Henning Schomerus
When a quantum-chaotic normal conductor is coupled to a superconductor, random-matrix theory predicts that a gap opens up in the excitation spectrum which is of universal size $E_g…
Entanglement between static and flying qubits in an Aharonov-Bohm double electrometer
Henning Schomerus, John P. Robinson
We consider the phase-coherent transport of electrons passing through an Aharonov-Bohm ring while interacting with a tunnel charge in a double quantum dot (representing a charge qu…
