Title: Localization of Matter Waves in Two-Dimensional Disordered Optical Potentials

Abstract

We consider ultracold atoms in 2D disordered optical potentials and calculate microscopic quantities characterizing matter wave quantum transport in the noninteracting regime. We derive the diffusion constant as a function of all relevant microscopic parameters and show that coherent multiple scattering induces significant weak localization effects. In particular, we find that even the strong localization regime is accessible with current experimental techniques and calculate the corresponding localization length.

  • We calculate the average transmission for {ital s}- and {ital p}-polarized electromagnetic (EM) waves and consequently the localization length of two-dimensional (2D) disordered systems which are periodic on the average; the periodic systems form a square lattice consisting of infinitely long cylinders parallel to each other and embedded in a different dielectric medium. In particular, we study the dependence of the localization length on the frequency, the dielectric function ratio between the scatterer and the background, and the filling ratio of the scatterer. We find that the gaps of the {ital s}-polarized waves can sustain a higher amount of disordermore » than those of the {ital p}-polarized waves, due to the fact that the gaps of the {ital s}-polarized waves are wider than those of the {ital p}-polarized waves. For high frequencies, the gaps of both types of waves easily disappear, the localization length is constant and it can take very small values. The optimum conditions for obtaining localization of EM waves in 2D systems will be discussed. {copyright} {ital 1996 The American Physical Society.}« less
  • We study the strong localization of atomic matter waves in a disordered potential created by atoms pinned at the nodes of a lattice, for both three-dimensional (3D) and two-dimensional (2D) systems. The localization length of the matter wave, the density of localized states, and the occurrence of energy mobility edges (for the 3D system), are numerically investigated as a function of the effective scattering length between the atomic matter wave and the pinned atoms. Both positive and negative matter wave energies are explored. Interesting features of the density of states are discovered at negative energies, where maxima in the densitymore » of bound states for the system can be interpreted in terms of bound states of a matter wave atom with a few pinned atomic scatterers. In 3D we found evidence of up to three mobility edges, one at positive energies, and two at negative energies, the latter corresponding to transitions between extended and localized bound states. In 2D, no mobility edge is found, and a rapid exponential-like increase of the localization length is observed at high energy.« less
  • The coherent matter waves of a dipolar condensate in deep two-dimensional (2D) tilted and nontilted optical lattices are studied both analytically and numerically. It is shown that, in tilted lattices, by properly designing the sign and the magnitude of the contact interaction and the dipolar interaction, it is possible to control the decoherence of Bloch oscillations. Contrary to the usual short-range interacting Bose system, long-lived Bloch oscillations of the dipolar condensate are achieved when the dipolar interaction, the contact interaction, and the lattice dimension satisfy an analytical condition. Furthermore, we predict that, in untilted lattices, stable coherent 2D moving solitonmore » and breather states of the dipolar condensate exist. This fact is very different from the purely short-range interacting Bose system (where the moving soliton cannot be stabilized in high-dimensional lattices). The dipolar interaction can lead to some novel phenomena that can not appear in short-range interacting BEC system.« less
  • We propose a method for achieving dynamically controllable transport of highly mobile matter-wave solitons in a driven two-dimensional optical lattice. Our numerical analysis based on the mean-field model and the theory based on the time-averaging approach demonstrate that a fast time-periodic rocking of the two-dimensional optical lattice enables efficient stabilization and manipulation of spatially localized matter wave packets via induced reconfigurable mobility channels.
  • We compute the frequency dependence of the localization length in a one-dimensional randomly disordered optical system, which on average is periodic, by studying the dependence of the transmissivity on the length of a finite random sample. Specifically, we consider a layered system of dielectric slabs with electromagnetic waves propagating perpendicular to the interfaces and compute the localization length for frequencies of these waves in and around the neighborhood of the band gaps in the photonic band structure of the average periodic system. The localization length is found to be very small in the gaps and much larger in the bands.more » We also compute the dependence of the localization length in the presence of dissipation (complex dielectric constant) and obtain a simple relationship, for frequencies of the electromagnetic waves in the allowed bands, between the localization length in the nondissipative system, the decay length in the nonrandom periodic system with dissipative terms, and the localization length in the presence of dissipation. For frequencies in the gaps the localization length appears to be insensitive to the presence of dissipation.« less
