NJP: Managing the Correlations of Ultracold Bosons in Triple Wells

Management of the correlations of Ultracold Bosons in triple wells

We investigated the correlations of ultracold many-boson systems in tilted triple wells with contact and dipolar interactions.

We were able to put forward a protocol to manage the correlation functions of the many-body state by tuning the depth and tilt of the lattice and the strength of the interactions between the particles.

Parametric excitation of a Bose-Einstein condensate: From Faraday waves to granulation

Surprisingly, the quantum version of granulation and Faraday waves can be produced in the same quantum system: a gas of trapped atoms cooled very close to absolute zero temperature.
