Isothermal and adiabatic elastic constants from virial fluctuations
Andrey Pereverzev
We derive expressions for classical isothermal and adiabatic elastic constants for periodic systems with the boundary contributions included explicitly. The potential-dependent par…
On the definition of heat current for periodic systems and its implications for simulations of thermal conductivity in solids
Andrey Pereverzev
We re-derive the expression for the heat current for a classical system subject to periodic boundary conditions and show that it can be written as a sum of two terms. The first ter…
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…
Electron transfer dynamics using projected modes
Andrey Pereverzev, Eric R. Bittner
For electron-phonon Hamiltonians with the couplings linear in the phonon operators we construct a class of unitary transformations that separate the normal modes into two groups. T…
On the derivation of exact eigenstates of the generalized squeezing operator
Andrey Pereverzev, Eric R. Bittner
We construct the states that are invariant under the action of the generalized squeezing operator for arbitrary positive integer . The states a…
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…
