We study a generic problem of dissipative quantum mechanics, a small local quantum
system with discrete states coupled in an arbitrary way (ie not necessarily linear) to several …

We consider electron transport through a quantum dot described by the Kondo model in the
regime of large transport voltage V in the presence of a magnetic field B with max⁡(V, B)≫ …

We analyze spin-dependent transport through spin valves composed of an interacting
quantum dot coupled to two ferromagnetic leads. The spin on the quantum dot and the linear …

We review the recent progress in theory and experiments with lateral triple quantum dots
with controlled electron numbers down to one electron in each dot. The theory covers …

Recent experimental progress has made it possible to detect in real-time single electrons
tunneling through Coulomb blockade nanostructures, thereby allowing for precise …

In this paper, we present a non-equilibrium quantum theory for transient electron dynamics
in nanodevices based on the Feynman–Vernon influence functional. Applying the exact …

We examine the properties of a dc-biased quantum dot in the Coulomb blockade regime.
For voltages V that are large compared to the Kondo temperature TK, the physics is …

We present a theory of full counting statistics for electron transport through interacting
electron systems with non-Markovian dynamics. We illustrate our approach for transport …

We present optimized implementations of the weak-coupling continuous-time Monte Carlo
method defined for nonequilibrium problems on the Keldysh contour. We describe and …

We examine the impact of spin effects on the nonequilibrium transport properties of a
nanowire hosting Majorana zero-energy modes at its ends, coupled to a quantum dot …
