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-…
