Discrete breathers in BEC with two- and three-body interactions in optical lattice
F. Kh. Abdullaev, A. Bouketir, A. Messikh +1
We investigate the properties of discrete breathers in a Bose-Einstein condensate with two- and three-body interactions in optical lattice. In the tight-binding approximation the G…

Entanglement and spin squeezing in the two-atom Dicke model
A. Messikh, Z. Ficek, M. R. B. Wahiddin
We analyze the relation between the entanglement and spin-squeezing parameter in the two-atom Dicke model and identify the source of the discrepancy recently reported by Banerjee a…
