Non-trivial dynamic regimes of small (nano-scale) quantum systems
V. A. Benderskii, E. I. Kats
Small (but still containing many atoms) quantum systems (traditionally termed nano-systems) are dramatically different from their macroscopic or genuine microscopic (atomic) cousin…
Vibrational energy transport in molecular wires
V. A. Benderskii, A. S. Kotkin, I. V. Rubtsov +1
Motivated by recent experimental observation (see e.g., I.V.Rubtsov, Acc. Chem. Res., v. 42, 1385 (2009)) of vibrational energy transport in CH_2O_N and CF_2_N molecular chains (N…
Revivals in Caldeira - Leggett Hamiltonian Dynamics
V. A. Benderskii, E. I. Kats, A. S. Kotkin
In this work we reconsider the problem discussed by Caldeira and Leggett (CL), and generalize their results for a quantum oscillator coupled bilinearly to a reservoir with dense di…
Dynamic and spectral mixing in nanosystems
V. A. Benderskii, E. I. Kats
In the framework of simple spin-boson Hamiltonian we study an interplay between dynamic and spectral roots to stochastic-like behavior. The Hamiltonian describes an initial vibrati…
New mechanism for non-trivial intra-molecular vibrational dynamics
V. A. Benderskii, E. I. Kats
We investigate the time evolution process of one selected (initially prepared by optical pumping) vibrational molecular state, coupled to all other intra-molecular vibrational stat…
Loschmidt echo and stochastic-like quantum dynamics of nano-particles
V. A. Benderskii, L. A. Falkovsky, E. I. Kats
We investigate time evolution of prepared vibrational state (system) coupled to a reservoir with dense spectrum of its vibrational states. We assume that the reservoir has an equid…
