Sub- to Super-Poissonian crossover of current noise in helical edge states coupled to a spin impurity in a magnetic field
Benedikt Probst, Pauli Virtanen, Patrik Recher
Edge states of two-dimensional topological insulators are helical and single-particle backscattering is prohibited by time-reversal symmetry. In this work, we show that an isotropi…
Signatures of nonlocal Cooper-pair transport and of a singlet-triplet transition in the critical current of a double-quantum-dot Josephson junction
B. Probst, F. Domínguez, A. Schroer +2
We study the critical Josephson current flowing through a double quantum dot weakly coupled to two superconducting leads. We use analytical as well as numerical methods to investig…
Controlling spin polarization of a quantum dot via a helical edge state
Benedikt Probst, Pauli Virtanen, Patrik Recher
We investigate a Zeeman-split quantum dot (QD) containing a single spin 1/2 weakly coupled to a helical Luttinger liquid (HLL) within a generalized master equation approach. The HL…
Fidelity of the near resonant quantum kicked rotor
Benedikt Probst, Remy Dubertrand, Sandro Wimberger
We present a perturbative result for the temporal evolution of the fidelity of the quantum kicked rotor, i.e. the overlap of the same initial state evolved with two slightly differ…
