Cold Bosonic Atoms in Optical Lattices
The dynamics of an ultracold dilute gas of bosonic atoms in an optical lattice can be described by a Bose-Hubbard model where the system parameters are controlled by laser light. We study the…
Dipole blockade and quantum information processing in mesoscopic atomic ensembles.
TLDR
A technique for manipulating quantum information stored in collective states of mesoscopic ensembles by optical excitation into states with strong dipole-dipole interactions that can be employed for controlled generation of collective atomic spin states as well as nonclassical photonic states and for scalable quantum logic gates is described.
Numerical solution of the Gross--Pitaevskii equation for Bose--Einstein condensation
We study the numerical solution of the time-dependent Gross-Pitaevskii equation (GPE) describing a Bose-Einstein condensate (BEC) at zero or very low temperature. In preparation for the numerics we…
The cold atom Hubbard toolbox
Abstract We review recent theoretical advances in cold atom physics concentrating on strongly correlated cold atoms in optical lattices. We discuss recently developed quantum optical tools for…
Entanglement of Atoms via Cold Controlled Collisions
We show that by using cold controlled collisions between two atoms one can achieve conditional dynamics in moving trap potentials. We discuss implementing two qubit quantum--gates and efficient…
Creation of effective magnetic fields in optical lattices: the Hofstadter butterfly for cold neutral atoms
We investigate the dynamics of neutral atoms in a 2D optical lattice which traps two distinct internal states of the atoms in different columns. Two Raman lasers are used to coherently transfer atoms…

Possible light-induced superconductivity in K3C60 at high temperature
TLDR
By exciting metallic K3C60 with mid-infrared optical pulses, a large increase in carrier mobility is induced, accompanied by the opening of a gap in the optical conductivity, which is observed at equilibrium when cooling metallic K 3C60 below Tc (20 kelvin).
Towards high-speed optical quantum memories
Quantum memories, capable of controllably storing and releasing a photon, are a crucial component for quantum computers1 and quantum communications2. To date, quantum memories3,4,5,6 have operated…
Many-particle entanglement in two-component Bose-Einstein condensates
We investigate schemes to dynamically create many-particle entangled states of a two-component Bose-Einstein condensate in a very short time proportional to $1/N,$ where N is the number of condensate…
