Structures and orientational transitions in thin films of tilted hexatic smectics
P. V. Dolganov, K. I. Belov, V. K. Dolganov +3
We present detailed systematic studies of structural transformations in thin liquid crystal films with the smectic-C to hexatic phase transition. For the first time all possible st…
A time lens for high resolution neutron time of flight spectrometers
K. Baumann, R. Gaehler, P. D. Grigoriev +1
We examine in analytic and numeric ways the imaging effects of temporal neutron lenses created by traveling magnetic fields. For fields of parabolic shape we derive the imaging equ…
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…
Vibrational Enhancement of the Effective Donor - Acceptor Coupling
M. Lazrek, D. J. Bicout, S. Jaziri +1
The paper deals with a simple three sites model for charge transfer phenomena in an one-dimensional donor (D) - bridge (B) - acceptor (A) system coupled with vibrational dynamics o…
Semiclassical model of ultrafast photoisomerization reactions
V. A. Benderskii, E. V. Vetoshkin, E. I. Kats +1
In this letter we propose a model which explains ultrafast and efficient photoisomerization reactions as driven by transitions between quasistationary states of one dimensional (1D…
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,…
