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…
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…
