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…
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…
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…
Transfer-matrix summation of path integrals for transport through nanostructures
Simon Mundinar, Alexander Hahn, Jürgen König +1
On the basis of the method of iterative summation of path integrals (ISPI), we develop a numerically exact transfer-matrix method to describe the nonequilibrium properties of inter…
Quantum Zeno Manipulation of Quantum Dots
N. Ahmadiniaz, M. Geller, J. König +4
We investigate whether and how the quantum Zeno effect, i.e., the inhibition of quantum evolution by frequent measurements, can be employed to isolate a quantum dot from its surrou…
