Matter-wave chaos with a cold atom in a standing-wave laser field
S. V. Prants
Coherent motion of cold atoms in a standing-wave field is interpreted as a propagation in two optical potentials. It is shown that the wave-packet dynamics can be either regular or…
Group-theoretical approach to study atomic motion in a laser field
S. V. Prants
Group-theoretical approach is applied to study behavior of lossless two-level atoms in a standing-wave laser field. Due to the recoil effect, the internal and external atomic degre…
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…
On the quantum (in)stability in cavity QED
S. V. Prants, M. Yu. Uleysky
The stability and instability of quantum motion is studied in the context of cavity quantum electrodynamics (QED). It is shown that the Jaynes-Cummings dynamics can be unstable in…
