We present a general theory of non-Markovian dynamics for open systems of noninteracting
fermions (bosons) linearly coupled to thermal environments of noninteracting fermions …

Current nonequilibrium Monte Carlo methods suffer from a dynamical sign problem that
makes simulating real-time dynamics for long times exponentially hard. We propose a new …

A generalized quantum master equation theory that governs the exact, nonperturbative
quantum dissipation and quantum transport is formulated in terms of hierarchically coupled …

We present a numerically exact steady-state inchworm Monte Carlo method for
nonequilibrium quantum impurity models. Rather than propagating an initial state to long …

In this paper, we develop a nonperturbation theory for describing decoherence dynamics of
electron charges in a double quantum dot gated by electrodes. We extend the Feynman …

The interaction of light with molecular conduction junctions is attracting growing interest as a
challenging experimental and theoretical problem on one hand, and because of its potential …

A quantum master equation (QME) is derived for the many-body density matrix of an open
current-carrying system weakly-coupled to two metal leads. The dynamics and the steady …

We propose a numerical renormalization group (NRG) approach to steady-state currents
through nanodevices. A discretization of the scattering-states continuum ensures the correct …

The interplay between interference effects and electron-electron interactions in electron
transport through an interacting double quantum dot system is investigated using a …

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 …
