Coherent control of atom dynamics in an optical lattice
H. L. Haroutyunyan, G. Nienhuis
On the basis of a simple exactly solvable model we discuss the possibilities for state preparation and state control of atoms in a periodic optical potential. In addition to the pe…
Resonances for coupled Bose-Einstein Condensates
H. L. Haroutyunyan, G. Nienhuis
We study some effects arising from periodic modulation of the asymmetry and the barrier height of a two-well potential containing a Bose-Einstein condensate. At certain modulation…
Diffraction and trapping in circular lattices
H. L. Haroutyunyan, G. Nienhuis
When a single two-level atom interacts with a pair of Laguerre-Gaussian beams with opposite helicity, this leads to an efficient exchange of angular momentum between the light fiel…
Phase dynamics of a multimode Bose condensate controlled by decay
H. L. Haroutyunyan, G. Nienhuis
The relative phase between two uncoupled BE condensates tends to attain a specific value when the phase is measured. This can be done by observing their decay products in interfere…
Analogy between a two-well Bose-Einstein condensate and atom diffraction
H. L. Haroutyunyan, G. Nienhuis
We compare the dynamics of a Bose-Einstein condensate in two coupled potential wells with atoms diffracting from a standing light wave. The corresponding Hamiltonians have an ident…
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…
