Quantum fluctuations in quasi-one-dimensional dipolar Bose-Einstein condensates
Daniel Edler, Chinmayee Mishra, Falk Wächtler +3
Recent experiments have revealed that beyond-mean-field corrections are much more relevant in weakly-interacting dipolar condensates than in their non-dipolar counterparts. We show…
Quantum phases of hardcore bosons in two coupled chains: A density matrix renormalization group study
Bradraj Pandey, S. Sinha, Swapan K. Pati
We consider hardcore bosons in two coupled chain of one dimensional lattices at half filling with repulsive intra-chain interaction and inter-chain attraction. This can be mapped o…
Phases and collective modes of Rydberg atoms in an optical lattice
K. Saha, S. Sinha, K. Sengupta
We chart out the possible phases of laser driven Rydberg atoms in the presence of a hypercubic optical lattice. We define a pseudospin degree of freedom whose up(down) components c…
Quantum dynamics and macroscopic quantum tunneling of two weakly coupled condensates
René John Kerkdyk, S. Sinha
We study the quantum dynamics of a Bose Josephson junction(BJJ) made up of two coupled Bose-Einstein condensates. Apart from the usual ac Josephson oscillations, two different dyna…
Dipolar gases in quasi one-dimensional geometries
S. Sinha, L. Santos
We analyze the physics of cold dipolar gases in quasi one-dimensional geometries, showing that the confinement-induced scattering resonances produced by the transversal trapping ar…
Critical rotation of a harmonically trapped Bose gas
P. Rosenbusch, D. S. Petrov, S. Sinha +5
We study experimentally and theoretically a cold trapped Bose gas under critical rotation, i.e. with a rotation frequency close to the frequency of the radial confinement. We ident…
