Driven Macroscopic Quantum Tunneling of Ultracold Atoms in Engineered Optical Lattices
Ramaz Khomeriki, Stefano Ruffo, Sandro Wimberger
Coherent macroscopic tunneling of a Bose-Einstein condensate between two parts of an optical lattice separated by an energy barrier is theoretically investigated. We show that by a…

Bose-Einstein condensates in accelerated double-periodic optical lattices: Coupling and Crossing of resonances
D. Witthaut, E. M. Graefe, S. Wimberger +1
We study the properties of coupled linear and nonlinear resonances. The fundamental phenomena and the level crossing scenarios are introduced for a nonlinear two-level system with…
