NJP: Correlations of ultracold dipolar bosons in optical lattices
![Correlations of strongly interacting ultracold dipolar bosons in optical lattices Correlations of strongly interacting ultracold dipolar bosons in optical lattices](/menu/images/Chatterjee_NJP2019.png)
We explore and analyze the rich structure of correlations of ultracold bosons with dipolar interactions in optical lattices and demonstrate that their quantum phases may be inferred from them.
NJP: Managing the Correlations of Ultracold Bosons in Triple Wells
![Management of the correlations of Ultracold Bosons in triple wells Management of the correlations of Ultracold Bosons in triple wells](/menu/images/Dutta2019_NJP.png)
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.

PRX: Granulation and Faraday waves in driven quantum systems
![Parametric excitation of a Bose-Einstein condensate: From Faraday waves to granulation Parametric excitation of a Bose-Einstein condensate: From Faraday waves to granulation](/menu/../data/BEC_Faraday_Granulation.png)
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.

Superfluids are distinguished from ordinary fluids by the quantized manner in which the rotation is manifested in them.
