    "abstract": "We study a Brownian motor, based on cold atoms in optical lattices, where\natomic motion can be induced in a controlled manner in an arbitrary direction,\nby rectification of isotropic random fluctuations. In contrast with ratchet\nmechanisms, our Brownian motor operates in a potential that is spatially and\ntemporally symmetric, in apparent contradiction to the Curie principle.\nSimulations, based on the Fokker-Planck equation, allow us to gain knowledge on\nthe qualitative behaviour of our Brownian motor. Studies of Brownian motors,\nand in particular ones with unique control properties, are of fundamental\ninterest because of the role they play in protein motors and their potential\napplications in nanotechnology. In particular, our system opens the way to the\nstudy of quantum Brownian motors.",
