Weak localization with nonlinear bosonic matter waves
Timo Hartmann, Josef Michl, Cyril Petitjean +4
We investigate the coherent propagation of dilute atomic Bose-Einstein condensates through irregularly shaped billiard geometries that are attached to uniform incoming and outgoing…
Spin-dependent Klein tunneling in graphene: Role of Rashba spin-orbit coupling
Ming-Hao Liu, Jan Bundesmann, Klaus Richter
Within an effective Dirac theory the low-energy dispersions of monolayer graphene in the presence of Rashba spin-orbit coupling and spin-degenerate bilayer graphene are described b…
Magnetotransport through graphene nanoribbons at high magnetic fields
S. Minke, S. H. Jhang, J. Wurm +6
We have investigated the magnetoresistance of lithographically prepared single-layer graphene nanoribbons in pulsed, perpendicular magnetic fields up to 60 T and performed correspo…
Bloch-Zener Oscillations in Graphene and Topological Insulators
Viktor Krueckl, Klaus Richter
We show that superlattices based on zero-gap semiconductors such as graphene and mercury telluride exhibit characteristic Bloch--Zener oscillations that emerge from the coherent su…
Conductance fluctuations in chaotic systems with tunnel barriers
Daniel Waltner, Jack Kuipers, Philippe Jacquod +1
Quantum effects are expected to disappear in the short-wavelength, semiclassical limit. As a matter of fact, recent investigations of transport through quantum chaotic systems have…
Universal spatial correlations in random spinor fields
Juan Diego Urbina, Michael Wimmer, Dominik Bauernfeind +3
We identify universal spatial fluctuations in systems with non trivial spin dynamics. To this end we calculate by exact numerical diagonalization a variety of experimentally releva…
