Some Old And New Puzzles In The Dynamics Of Fluids
Ihor Mryglod, Vasyl' Ignatyuk
One of the basic concepts of modern physics with a long prehistory is a fluid, which means a substance that flows under an applied shear stress. In this sense fluids form a wide su…
Master equation for open quantum systems: Zwanzig-Nakajima projection technique and the intrinsic bath dynamics
V. V. Ignatyuk, V. G. Morozov
The non-Markovian master equation for open quantum systems is obtained by generalization of the ordinary Zwanzig-Nakajima (ZN) projection technique. To this end, a coupled chain of…
A simple closure procedure for the study of velocity autocorrelation functions in fluids as a "bridge" between different theoretical approaches
V. V. Ignatyuk, I. M. Mryglod, T. Bryk
Velocity autocorrelation functions (VAF) of the fluids are studied on short- and long-time scales within a unified approach. This approach is based on an effective summation of the…
A simple ansatz for the study of velocity autocorrelation functions in fluids at different timescales
V. V. Ignatyuk, I. M. Mryglod, T. Bryk
A simple ansatz for the study of velocity autocorrelation functions in fluids at different timescales is proposed. The ansatz is based on an effective summation of the infinite con…
Bath dynamics in an exactly solvable qubit model with initial qubit-environment correlations
V. V. Ignatyuk, V. G. Morozov
We study the bath dynamics in the dephasing model of a two-state quantum system (qubit) coupled to an environment of harmonic oscillators. This model was shown [Morozov et al., Phy…
A temperature behavior of the frustrated translational mode of adsorbate and the nature of the "adsorbate-substrate" interaction
V. V. Ignatyuk
A temperature behavior of the frustrated translational mode (T-mode) of a light particle, coupled by different regimes of ohmicity to the surface, is studied within a formalism of…
Coherence, decoherence, and memory effects in the problems of quantum surface diffusion
V. V. Ignatyuk
We consider surface diffusion of a single particle, which performs site-to-site under-barrier hopping, fulfils intrasite motion between the ground and the first excited states with…
