Relaxation of quantum dots in a magnetic field at finite bias -- charge, spin and heat currents
Joren Vanherck, Jens Schulenborg, Roman B. Saptsov +2
We perform a detailed study of the effect of finite bias and magnetic field on the tunneling-induced decay of the state of a quantum dot by applying a recently discovered general d…
Time-dependent quantum transport: causal superfermions, exact fermion-parity protected decay mode, and Pauli exclusion principle for mixed quantum states
R. B. Saptsov, M. R. Wegewijs
We extend the recently developed causal superfermion approach to the real-time transport theory to time-dependent decay problems.Its usefulness is illustrated for the Anderson mode…
Fermionic superoperators for zero-temperature non-linear transport: real-time perturbation theory and renormalization group for Anderson quantum dots
R. B. Saptsov, M. R. Wegewijs
We study the transport through a strongly interacting Anderson quantum dot at zero-temperature using the real-time renormalization group (RT-RG) in the framework of a kinetic equat…
Condensation and vortex formation in Bose-gas upon cooling
E. A. Brener, S. V. Iordanskiy, R. B. Saptsov
The mechanism for the transition of a Bose gas to the superfluid state via thermal fluctuations is considered. It is shown that in the process of external cooling some critical flu…
