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…

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…

Damped harmonic oscillator: pure states of the bath and exact master equations
Andrey Pereverzev
Time evolution of a harmonic oscillator linearly coupled to a heat bath is compared for three classes of initial states for the bath modes - grand canonical ensemble, number states…
