DESCRIPTION:Atoms interacting with standing waves of laser light experienc
 e a periodic potential (optical lattice)\, and there is only a small rate 
 of spontaneous scattering (leading to heating)  if the laser operates far 
 from the atomic resonance frequency.  Loading cold\n(rubidium) atoms from 
 a Bose-Einstein condensate into such an optical lattice gives a strongly-c
 orrelated quantum system that is highly controllable. In our experiment th
 e optical lattice is rotated so that\nthe atoms experience an artificial m
 agnetic field\, i.e. the Hamiltonian of the atoms in the rotating frame re
 sembles that of a charged particle in a strong magnetic field. In the futu
 re\, we plan to use this for Direct Quantum Simulation of the Quantum Hall
  Effect. \n\n \n\n
