The short-time dynamics of correlated systems is strongly influenced by initial correlations, giving rise to an additional collision integral in the non-Markovian kinetic equation. Exact cancellation of the two integrals is found if the initial state is thermal equilibrium, which is an important consistency criterion. Analytical results are given for the time evolution of the correlation energy, which are confirmed by comparisons with molecular dynamics simulations.

Fast dynamics of molecular bridges

We address the dynamics of open quantum systems, in which complex finite time initial conditions, an ensuing rapid non-equilibrium transient, quantum interferences and their attenuation play

Correlated initial condition for an embedded process by time partitioning

Study of transients in the electron quantum transport by nonequilibrium Green’s function often requires an explicit inclusion of correlations at a finite initial time. For processes embedded in a

This problem may be attacked for a variant of the generic molecular island model, an Anderson impurity linked between two bulk metallic leads by tunneling junctions: our electrodes are ferromagnetic,

The ultrafast dynamics of a neutral, ultracold plasma following an energy landscape shift is studied theoretically and with simulation. To lowest order in time, the inertial dynamics on the new

We present basic equations of nonequilibrium thermo field dynamics of dense quantum systems. A formulation of nonequilibrium thermo field dynamics has been performed using the nonequilibrium
