"Ping-pong" electron transfer. II. Multiple reflections of the Loschmidt echo and the wave function trapping by an acceptor
V. N. Likhachev, T. Yu. Astakhova, G. A. Vinogradov
This paper continues the preceding paper on the problem of quantum dynamics on the lattice. Firstly we consider the multiple reflections of the wave function (Loschmidt echo). The…
"Ping-pong" electron transfer. I. First reflection of the Loschmidt echo
V. N. Likhachev, T. Yu. Astakhova, G. A. Vinogradov
Quantum dynamics of the electron wave function on one-dimensional lattice is considered. The lattice consists of equal sites and one impurity site. The impurity site differs fr…
Polarons on one-dimensional lattice. II. Moving polaron
T. Yu. Astakhova, V. N. Likhachev, G. A. Vinogradov
In the present study we revise the possible polaron contribution to the charge and energy transfer over long distances in biomolecules like DNA. The harmonic and the simple inharmo…
Polarons in the harmonic lattice. I. Standing polaron
V. N. Likhachev, T. Yu. Astakhova, G. A. Vinoghradov
We obtain analytical expressions for the large- and small-radius polarons on the one-dimensional lattice in the TBA approximation. The equations of motion for this model are treate…
Heat conductivity in the beta-FPU lattice. Solitons and breathers as energy carriers
T. Yu. Astakhova, V. N. Likhachev, G. A. Vinogradov
This paper consists of two parts. The first part proposes a new methodological framework within which the heat conductivity in 1D lattices can be studied. The total process of heat…
Heat conductance in nonlinear lattices at small temperature gradients
T. Yu. Astakhova, V. N. Likhachev, G. A. Vinogradov
This paper proposes a new methodological framework within which the heat conductance in 1D lattices can be studied. The total process of heat conductance is separated into two part…
