Quantum walks and quantum simulations with Bloch oscillating spinor atoms
D. Witthaut
We propose a scheme for the realization of a quantum walker and a quantum simulator for the Dirac equation with ultracold spinor atoms in driven optical lattices. A precise control…
Nonlinear Landau-Zener tunneling in quantum phase space
F. Trimborn, D. Witthaut, V. Kegel +1
We present a detailed analysis of the Landau-Zener problem for an interacting Bose-Einstein condensate in a time-varying double-well trap, especially focussing on the relation betw…
Casimir-Lifshitz Interaction between Dielectrics of Arbitrary Geometry: A Dielectric Contrast Perturbation Theory
Ramin Golestanian
The general theory of electromagnetic--fluctuation--induced interactions in dielectric bodies as formulated by Dzyaloshinskii, Lifshitz, and Pitaevskii is rewritten as a perturbati…
Dissipation induced coherence and stochastic resonance of an open two-mode Bose-Einstein condensate
D. Witthaut, F. Trimborn, S. Wimberger
We discuss the dynamics of a Bose-Einstein condensate in a double-well trap subject to phase noise and particle loss. The phase coherence of a weakly-interacting condensate, experi…
Non-contact rack and pinion powered by the lateral Casimir force
Arash Ashourvan, MirFaez Miri, Ramin Golestanian
The lateral Casimir force is employed to propose a design for a potentially wear-proof rack and pinion with no contact, which can be miniaturized to nano-scale. The robustness of t…
Lifshitz Interaction between Dielectric Bodies of Arbitrary Geometry
Ramin Golestanian
A formulation is developed for the calculation of the electromagnetic--fluctuation forces for dielectric objects of arbitrary geometry at small separations, as a perturbative expan…
