Mean field analysis of quantum phase transitions in a periodic optical superlattice

Arya Dhar, Manpreet Singh, Ramesh V. Pai +1

In this paper we analyze the various phases exhibited by a system of ultracold bosons in a periodic optical superlattice using the mean field decoupling approximation. We investiga…

Three body on-site interactions in ultracold bosonic atoms in optical lattices and superlattices

Manpreet Singh, Arya Dhar, Tapan Mishra +2

The Mott insulator-superfluid transition for ultracold bosonic atoms in an optical lattice has been extensively studied in the framework of the Bose-Hubbard model with two-body on-…

The Inhomogeneous Extended Bose-Hubbard Model: A Mean-Field Theory

Jamshid Moradi Kurdestany, Ramesh V. Pai, Rahul Pandit

We develop an inhomogeneous mean-field theory for the extended Bose-Hubbard model with a quadratic, confining potential. In the absence of this potential, our mean-field theory yie…

Bose-Hubbard Models in Confining Potentials: An Inhomogeneous Mean-Field Theory

Ramesh V. Pai, Jamshid Moradi Kurdestany, K. Sheshadri +1

We present an extensive study of Mott insulator (MI) and superfluid (SF) shells in Bose-Hubbard (BH) models for bosons in optical lattices with harmonic traps. For this we develop…
