Coherent excitation of a two-state system by a Lorentzian field
Aida Shiroyan, Genko S. Vasilev, Nikolay V. Vitanov
We study the coherent excitation of a two-state quantum system by a field with a Lorentzian temporal envelope and constant carrier frequency. The associated differential equation a…
Morris-Shore transformation for non-degenerate systems
K. N. Zlatanov, G. S. Vasilev, N. V. Vitanov
The Morris-Shore (MS) transformation is a powerful tool for decomposition of the dynamics of multistate quantum systems to a set of two-state systems and uncoupled single states. I…
Morris-Shore transformation with unequal detunings
G. S. Vasilev, N. V. Vitanov
The aim of this paper is to analyze the MS transformation in the case of weak deviation of the condition for equal detunings, which in necessary for factorization towards set of tw…
Superadiabatic optimization via Dykhne-Davis-Pechukas (DDP) method
G. S. Vasilev, N. V. Vitanov
This paper we propose how to apply the Dykhne-Davis-Pechukas (DDP) method for optimization of adiabatic passage in a two-state system in the second adiabtic basis.
Exact solution of the optical Bloch equation for the Demkov model
G. S. Vasilev, P. A. Ivanov, N. V. Vitanov
An exact analytic solution is presented for coherent resonant excitation of a two-state quantum system driven by a time-dependent pulsed external field described by Demkov model in…
Coherent excitation of two-state system by a Lorentzian filed
G. S. Vasilev, N. V. Vitanov
This work presents an analytic description of the coherent excitation of a two-state quantum system by an external field with a Lorentzian temporal shape and a constant frequency.…
