Direct two-photon excitation of isomeric transition in thorium-229 nucleus
V. I. Romanenko, Ye. G. Udoviskaya, L. P. Yatsenko +3
A possibility of the two-photon excitation of an isomeric state in a nucleus of thorium-229 has been discussed. The fluorescence intensity of the excitation is demonstrated to be i…
Capture of atoms and small particles in an optical trap formed by sequences of counter-propagating light pulses with a large area
Victor I. Romanenko, Leonid P. Yatsenko
A new trap for atoms and small particles based on the interaction between an atom and the field of counter-propagating light pulses that are partially superposed in time has been p…
Preparation of nondegenerate coherent superpositions in a three-state ladder system assisted by Stark Shifts
N. Sangouard, L. P. Yatsenko, B. W. Shore +1
We propose a technique to prepare coherent superpositions of two nondegenerate quantum states in a three-state ladder system, driven by two simultaneous fields near resonance with…
Pulse-driven near-resonant quantum adiabatic dynamics: lifting of quasi-degeneracy
L. P. Yatsenko, S. Guerin, H. R. Jauslin
We study the quantum dynamics of a two-level system driven by a pulse that starts near-resonant for small amplitudes, yielding nonadiabatic evolution, and induces an adiabatic evol…
