A geometrical approach to the mean density of states in many-body quantum systems
Quirin Hummel, Juan Diego Urbina, Klaus Richter
We present a novel analytical approach for the calculation of the mean density of states in many-body systems made of confined indistinguishable and non-interacting particles. Our…
Many-body localized molecular orbital approach to molecular transport
Dmitry A. Ryndyk, Andrea Donarini, Milena Grifoni +1
An ab initio based theoretical approach to describe nonequilibrium many-body effects in molecular transport is developed. We introduce a basis of localized molecular orbitals and f…
Transport moments and Andreev billiards with tunnel barriers
Jack Kuipers, Klaus Richter
Open chaotic systems are expected to possess universal transport statistics and recently there have been many advances in understanding and obtaining expressions for their transpor…
A sub-determinant approach for pseudo-orbit expansions of spectral determinants in quantum maps and quantum graphs
Daniel Waltner, Sven Gnutzmann, Gregor Tanner +1
We study implications of unitarity for pseudo-orbit expansions of the spectral determinants of quantum maps and quantum graphs. In particular, we advocate to group pseudo-orbits in…
Spin transmission control in helical magnetic fields
Henri Saarikoski, Tobias Dollinger, Klaus Richter
We calculate spin transport in two-dimensional waveguides in the presence of spatially modulated Zeeman-split energy bands. We show that in a regime where the spin evolution is pre…
Probing the Band Topology of Mercury Telluride through Weak Localization and Antilocalization
Viktor Krueckl, Klaus Richter
We analyze the effect of weak localization (WL) and weak antilocalization (WAL) in the electronic transport through HgTe/CdTe quantum wells. We show that for increasing Fermi energ…
