Competing tunneling trajectories in a 2D potential with variable topology as a model for quantum bifurcations
V. A. Benderskii, E. V. Vetoshkin, E. I. Kats +2
We present a path - integral approach to treat a 2D model of a quantum bifurcation. The model potential has two equivalent minima separated by one or two saddle points, depending o…
Disclination motion in hexatic and smectic-C films
E. I. Kats, V. V. Lebedev, S. V. Malinin
We present theoretical study of a single disclination motion in a thin free standing hexatic (or smectic-C) film, driven by a large-scale inhomogeneity in the bond (or director) an…
Semiclassical approach to states near potential barrier top
V. A. Benderskii, E. V. Vetoshkin, ; E. I. Kats
Within the framework of the instanton approach we present analytical results for the following model problems: (i) particle penetration through a parabolic potential barrier, where…
Sound modes in composite incommensurate crystals
R. Currat, E. I. Kats, I. Luk'yanchuk
We propose a simple phenomenological model describing composite crystals, constructed from two parallel sets of periodic inter-penetrating chains. In the harmonic approximation and…
Base pair dynamic assisted charge transport in DNA
E. I. Kats, V. V. Lebedev
An 1d model with time-dependent random hopping is proposed to describe charge transport in DNA. It admits to investigate both diffusion of electrons and their tunneling between dif…
