Decreasing critical temperature of gas BEC in spatially periodic potential and relevance to experiments treated by Mott-Hubbard model
A. Zh. Muradyan, G. A. Muradyan
It is shown that the critical temperature of gas Bose-Einstein condensation decreases in deepening periodic potential, in contrast to common regularity in a separate potential well…
Anomalous transparency for near-top Bloch states of periodic potential
A. Zh. Muradyan, G. A. Muradyan
In the paper are considered stationary (Bloch) states of a particle, in the field of periodic biparabolic type potential. It is shown that while the particle's energy decreases in…
Stationary states of Jaynes-Cummings model with atomic center-of-mass quantum motion: direct comparison of standing-wave and counterpropagating-waves cases
A. Zh. Muradyan, G. A. Muradyan
The eigenstate problem of the Jaynes-Cummings model on the basis of complete Hamiltonian, including the center-of -mass kinetic energy operator, is treated. The energy spectrum and…
Large Scale (Multiphoton) Evolution of Atomic Energy Level's Mean Momentum for Single-Photon Absorption/Emission Process
A. Zh. Muradyan, H. L. Haroutyunyan
It is shown that a two-level atom, being initially in general superposition state of ground and excited energy levels with mutually different momentum distributions there, gets a l…
