Atomic current across an optical lattice.

چکیده
We devise a microscopic model for the emergence of a collision-induced, fermionic atomic current across a tilted optical lattice. Tuning the--experimentally controllable--parameters of the microscopic dynamics allows us to switch from Ohmic to negative differential conductance.

Mesoscopic transport of fermions through an engineered optical lattice connecting two reservoirs
We study transport of fermions in a system composed of a short optical lattice connecting two finite atomic reservoirs at different filling levels. The average equilibration current through the optical lattice, for strong latticereservoir coupling and finite temperatures, is calculated within the Landauer formalism using a nonequilibrium Green’s functions approach. We moreover determine quantum...
متن کاملTransport of strong-coupling polarons in optical lattices
We study the transport of ultracold impurity atoms immersed in a BoseEinstein condensate (BEC) and trapped in a tight optical lattice. Within the strongcoupling regime, we derive an extended Hubbard model describing the dynamics of the impurities in terms of polarons, i.e. impurities dressed by a coherent state of Bogoliubov phonons. Using a generalized master equation based on this microscopic...
متن کاملUltra-Large Scale Simulations for Superconductor MgB2 Device toward Nuclear Application and Fundamental Issues in Nano-superconductivity and Atomic Fermi Gas Loaded on Optical Lattice
We performed large-scale numerical simulations on non-equilibrium superconducting dynamics after a neutron capture at the superconducting transition edge in MgB2 by solving the time-dependent Ginzburg-Landau equation coupled with the Maxwell and the heat diffusion equations. The simulations were executed under the current-biased condition in order to explain experimental results carried out in ...
متن کاملDissipation-induced symmetry breaking in a driven optical lattice.
We analyze the atomic dynamics in an ac driven periodic optical potential which is symmetric in both time and space. We experimentally demonstrate that in the presence of dissipation the symmetry is broken, and a current of atoms through the optical lattice is generated as a result.
متن کاملAtomic Bose and Anderson glasses in optical lattices.
An ultracold atomic Bose gas in an optical lattice is shown to provide an ideal system for the controlled analysis of disordered Bose lattice gases. This goal may be easily achieved under the current experimental conditions by introducing a pseudorandom potential created by a second additional lattice or, alternatively, by placing a speckle pattern on the main lattice. We show that, for a nonco...
