With this work we elaborate on the physics of quantum noise in thermal equilibrium and in
stationary nonequilibrium. Starting out from the celebrated quantum fluctuation-dissipation …

Abstract The Schrödinger–Langevin equation (SLE) is considered as an effective open
quantum system formalism suitable for phenomenological applications involving a quantum …

The continuous-time differential Lyapunov equation is widely used in linear optimal control
theory, a branch of mathematics and engineering. In quantum physics, it is known to appear …

The stability of charge carriers in conjugated polymers is investigated in terms of a
nonadiabatic evolution method by using an extended version of the Su–Schrieffer–Heeger …

We present an algorithm for carrying out Langevin dynamics simulations on complex rigid
bodies by incorporating the hydrodynamic resistance tensors for arbitrary shapes into an …

We consider the motion of a Brownian particle moving in a potential field and driven by
dichotomous noise with exponential correlation. Traditionally, the analytic as well as the …

We investigate a nonequilibrium phase transition in a dissipative and coherent quantum
spin system using the quantum Langevin equation and mean-field theory. Recently, the …

The state-dependent diffusion, which concerns the Brownian motion of a particle in
inhomogeneous media has been described phenomenologically in a number of ways …

Fundamental understanding of complex dynamics in many-particle systems on the atomistic
level is of utmost importance. Often the systems of interest are of macroscopic size but can …

The motion of a particle along a channel of finite width is known to be affected by either the
presence of energy barriers or changes in the bias forces along the channel direction. By …
