We review recent theoretical advances in cold atom physics concentrating on strongly
correlated cold atoms in optical lattices. We discuss recently developed quantum optical …

Abstract Superflow of a Bose–Einstein condensate in an optical lattice is represented by a
Bloch wave, a plane wave with periodic modulation of the amplitude. We review the …

Entanglement-based technologies, such as quantum information processing, quantum
simulations and quantum-enhanced metrology, have the potential to revolutionize our way …

A neutral impurity atom immersed in a dilute Bose-Einstein condensate (BEC) can have a
bound ground state in which the impurity is self-localized. In this polaronlike state, the …

Bose-Einstein condensates have been produced in an optical box trap. This optical trap type
has strong confinement in two directions comparable to that which is possible in an optical …

We investigate adiabatic evolution of quantum states as governed by the nonlinear
Schrödinger equation and provide examples of applications with a nonlinear tunneling …

We study the dynamics of an atomic quantum dot, ie, a single atom in a tight optical trap
which is coupled to a superfluid reservoir via laser transitions. Quantum interference …

We propose a two-qubit collisional phase gate that can be implemented with available atom
chip technology and present a detailed theoretical analysis of its performance. The gate is …

We present an experimental method to create a single high frequency optical trap for atoms
based on an elongated Hermite-Gaussian TEM01 mode beam. This trap results in …
