The effect of Landau-Zener tunnelings on the nonlinear dynamics of cold atoms in a modulated laser field
Victor Argonov
We study the motion of a cold atom in a frequency-modulated standing laser wave. If the detuning between the atomic electronic transition and the field is large, the atom moves in…
Theory of dissipative chaotic atomic transport in an optical lattice
V. Yu. Argonov, S. V. Prants
We study dissipative transport of spontaneously emitting atoms in a 1D standing-wave laser field in the regimes where the underlying deterministic Hamiltonian dynamics is regular a…
Manifestation of Hamiltonian chaos in an open quantum system with ballistic atoms in an optical lattice
V. Yu. Argonov, S. V. Prants
Manifestation of dynamical instability and Hamiltonian chaos in the fundamental near-resonant matter-radiation interaction has been found analitically and in a Monte Carlo simulati…
Theory of chaotic atomic transport in an optical lattice
V. Yu. Argonov, S. V. Prants
A semiclassical theory of chaotic atomic transport in a one-dimensional nondissipative optical lattice is developed. Using the basic equations of motion for the Bloch and translati…
Nonlinear coherent dynamics of an atom in an optical lattice
V. Yu. Argonov, S. V. Prants
We consider a simple model of lossless interaction between a two-level single atom and a standing-wave single-mode laser field which creates a one-dimensional optical lattice. Inte…
Entanglement, fidelity, and quantum-classical correlations with an atom walking in a quantized cavity field
S. V. Prants, M. Yu. Uleysky, V. Yu. Argonov
Stability and instability of quantum evolution are studied in the interaction between a two-level atom with photon recoil and a quantized field mode in an ideal cavity, the basic m…
