Accuracy of Semiclassics: Comparative Analysis of WKB and Instanton Approaches
V. A. Benderskii, E. V. Vetoshkin, E. I. Kats
We analyze quantitatively the accuracy of eigenfunction and eigenvalue calculations in the frame work of WKB and instanton semiclassical methods. We show that to estimate the accur…
Bridge-mediated Donor-Acceptor Effective Coupling: Exact theoretical description
D. J. Bicout, F. Varchon, E. Kats
An exact expression of the bridge-mediated donor-acceptor effective coupling, is derived. For systems represented by a tight-binding Hamiltonian with nearest-neighbor interactions,…
Quasistationary states and coherent versus incoherent transitions for crossing diabatic potentials
V. A. Benderskii, E. V. Vetoshkin, E. I. Kats
We investigate coherent and incoherent tunneling phenomena in conditions of crossing diabatic potentials. We consider a model of two crossing parabolic diabatic potentials with an…
Sound modes broadening in quasicrystals
M. de Boissieu, R. Currat, S. Francoual +1
We propose a simple phenomenological model to analyze vibrational characteristics of quasicrystals (QCs). The interpretation of the obtained recently data is based on the existence…
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…
Novel Cholesteric Phase in Dispersions of Nucleic Acids due to Polymeric Chelate Bridges
V. L. Golo, E. I. Kats, Yu. S. Volkov +2
We consider cholesteric liquid-crystalline DNA dispersions, and show that polymeric (Dau-Cu) complexes, the so-called bridges, between pairs of DNA molecules may generate a super l…
