Crystalline Phases of Laser-Driven Dipolar Bose-Einstein Condensates
Chinmayee Mishra, Stefan Ostermann, Farokh Mivehvar +1
Although crystallization is a ubiquitous phenomenon in nature, crystal formation and melting still remain fascinating processes with several open questions yet to be addressed. In…
Non-destructive monitoring of Bloch oscillations in an optical cavity
H. Keßler, J. Klinder, B. P. Venkatesh +2
Bloch oscillations are a hallmark of coherent wave dynamics in periodic potentials. They occur as the response of quantum mechanical particles in a lattice if a weak force is appli…
Nonlinear Phenomena of Ultracold Atomic Gases in Optical Lattices: Emergence of Novel Features in Extended States
Gentaro Watanabe, B. Prasanna Venkatesh, Raka Dasgupta
The system of a cold atomic gas in an optical lattice is governed by two factors: nonlinearity originating from the interparticle interaction, and the periodicity of the system set…
Attraction-induced dynamical stability of a Bose-Einstein condensate in a nonlinear lattice
Raka Dasgupta, B. Prasanna Venkatesh, Gentaro Watanabe
We study multiple-period Bloch states of a Bose-Einstein condensate with spatially periodic interactomic interaction. Solving the Gross-Pitaevskii equation for the continuum model,…
Backaction-Driven Transport of Bloch Oscillating Atoms in Ring Cavities
J. Goldwin, B. Prasanna Venkatesh, D. H. J. O'Dell
We predict that an atomic Bose-Einstein condensate strongly coupled to an intracavity optical lattice can undergo resonant tunneling and directed transport when a constant and unif…
