Effective time-dependent temperature for fermionic master equations beyond the Markov and the secular approximations
Lukas Litzba, Eric Kleinherbers, Jürgen König +2
We consider a fermionic quantum system exchanging particles with an environment at a fixed temperature and study its reduced evolution by means of a Redfield-I equation with time-d…
Dark versus blocking states in electronic transport: a Lee-Yang zero analysis of full counting statistics
Johann Zöllner, Philipp Stegmann, Jürgen König +1
Electronic transport through nanostructures can be suppressed by coherent population trapping, in which quantum coherence leads to a dark state that decouples from the drain electr…
Relaxation to persistent currents in a Hubbard trimer coupled to fermionic baths
Nikodem Szpak, Gernot Schaller, Ralf Schützhold +1
We consider a ring of fermionic quantum sites, modeled by the Fermi--Hubbard Hamiltonian, in which electrons can move and interact strongly via the Coulomb repulsion. The system is…
Unraveling spin dynamics from charge fluctuations
Eric Kleinherbers, Hendrik Mannel, Jens Kerski +3
The use of single electron spins in quantum dots as qubits requires detailed knowledge about the processes involved in their initialization and operation as well as their relaxatio…
Quasi-particle propagation across semiconductor-Mott insulator interfaces
Jan Verlage, Friedemann Queisser, Nikodem Szpak +3
As a prototypical example for a heterostructure combining a weakly and a strongly interacting quantum many-body system, we study the interface between a semiconductor and a Mott in…
Full counting statistics in a Majorana single-charge transistor
Eric Kleinherbers, Alexander Schünemann, Jürgen König
We study full counting statistics of electron transport through a Majorana single-charge transistor. At low bias voltage, transport is dominated by the so-called Josephson-Majorana…
