Semiclassical description of wave packet revival
(American Physical Society, 2009-11)
We test the ability of semiclassical theory to describe quantitatively the revival of quantum wave packets-a long time phenomena-in the one dimensional quartic oscillator (a Kerr type Hamiltonian). Two semiclassical theories ...
Semiclassical scaling functions of sine-Gordon model
(Elsevier B.V., 2004-11-08)
We present an analytic study of the finite size effects in sine-Gordon model, based on the semi-classical quantization of an appropriate kink background defined on a cylindrical geometry. The quasi-periodic kink is realized ...
Semiclassical two-step model for strong-field ionization
(American Physical Society, 2016-07)
We present a semiclassical two-step model for strong-field ionization that accounts for path interferences of tunnel-ionized electrons in the ionic potential beyond perturbation theory. Within the framework of a classical ...
An initial value representation for the coherent state propagator with complex trajectories

VACUUM POLARIZATION EFFECTS ON QUASINORMAL MODES IN ELECTRICALLY CHARGED BLACK HOLE SPACE-TIMES
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2010)
We investigate the influence of vacuum polarization of quantum massive fields on the scalar sector of quasinormal modes in spherically symmetric black holes. We consider the evolution of a massless scalar field on the ...
