Hamiltonian approach for the wave packet dynamics: Beyond Gaussian wave functions
Andrey Pereverzev, Eric R. Bittner
It is well known that the Gaussian wave packet dynamics can be written in terms of Hamilton equations in the extended phase space that is twice as large as in the corresponding cla…
Time-convolutionless master equation dynamics for charge-transfer processes between semiconducting polymers
Eric R. Bittner, Andrey Pereverzev
We present here a brief overview of our work in developing a convolutionless quantum master equation approach suitable for mesoscopic sized systems. Our final equation can be used…
Time-convolutionless master equation for mesoscopic electron-phonon systems
Andrey Pereverzev, Eric R. Bittner
The time-convolutionless master equation for the electronic populations is derived for a generic electron-phonon Hamiltonian. The equation can be used in the regimes where the gold…
Constraints on the two-particle distribution function due to the permutational symmetry of the higher order distribution functions
Andrey Pereverzev
We investigate how the range of parameters that specify the two-particle distribution function is restricted if we require that this function be obtained from the orde…
Quantum transport in chains with noisy off-diagonal couplings
Andrey Pereverzev, Eric R. Bittner
We present a model for conductivity and energy diffusion in a linear chain described by a quadratic Hamiltonian with Gaussian noise. We show that when the correlation matrix is dia…
Least paradoxical states of the Schrödinger cat
Andrey Pereverzev
Modeling the Schrödinger cat by a two state system and assuming that the cat is coupled to the environment we look for the least paradoxical states of the Schrödinger cat in the fo…
