Quantum manipulation of two-color stationary light: Quantum wavelength conversion

S. A. Moiseev, B. S. Ham

We present a quantum manipulation of a traveling light pulse using double atomic coherence for two-color stationary light and quantum frequency conversion. The quantum frequency co…

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…

Star-quantization of an infinite wall

Sergei Kryukov, Mark A. Walton

In deformation quantization (a.k.a. the Wigner-Weyl-Moyal formulation of quantum mechanics), we consider a single quantum particle moving freely in one dimension, except for the pr…

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…

Manipulative resonant nonlinear optics: nonlinear interference effects and quantum control of nonlinearity, dispersion, transparency and inversionless amplification in an extended strongly-absorbing inhomogeneously-broadened medium

A. K. Popov, S. A. Myslivets, Thomas F. George

Specific features of nonlinear interference processes at quantum transitions in near- and fully-resonant optically-dense Doppler-broadened medium are studied. The feasibility of ov…
