Quantum computers, though not yet available on the market, will revolutionize the future of
information processing. Quantum computers for special purposes like quantum simulators …

During the last decade, many exciting phenomena have been experimentally observed and
theoretically predicted for ultracold atoms in optical lattices. This paper reviews these rapid …

A set of collective spin states is derived for a trapped Bose-Einstein condensate in which
atoms have three internal hyperfine spins. These collective states minimize the interaction …

We study the spin-mixing dynamics of an f= 1 spinor condensate. We show that the
dynamics is sensitive to the relative phase and particle number distribution among the …

The exact eigenspectra and eigenstates of spin-1 and spin-2 Bose-Einstein condensates
(BECs) are found, and their response to a weak magnetic field is studied and compared with …

It is shown that the dynamics of a two-level ion in any position other than at the antinode of a
standing wave that moves in a harmonic trap** potential can be described by Jaynes …

It is shown that the system of a three-level atom coupled to two modes of quantized cavity
fields in the Ξ configuration with arbitrary detunings can be exactly reduced to a two-level …

We study the superfluid–Mott insulator (SF-MI) transition of spin-1 bosons interacting
antiferromagnetically in an optical lattice. Starting from a Bose-Hubbard tight-binding model …

In this article we present a simple and unified procedure to solve various nonlinear two-level
Jaynes-Cummings models. By establishing their similarity to the model describing a spin …

We present a method for obtaining a simple relation between bulk and cavity-modified
Raman gains for microcavities with arbitrary geometric shapes. The analytical expression for …
