Lattice bosons in a quasi-disordered environment: The effects of a superlattice potential on single particle and many particle properties
R. Ramakumar, A. N. Das, S. Sil
In this paper we present a theoretical investigation of the effect of a superlattice potential on some properties of non-interacting bosons in one dimensional lattices with Aubry-A…
Lattice bosons in a quasi-disordered environment: The effects of next-nearest-neighbor hopping on localization and Bose-Einstein condensation
R. Ramakumar, A. N. Das, S. Sil
We present a theoretical study of the effects of the next-nearest-neighbor (NNN) hopping () on the properties of non-interacting bosons in optical lattices in the presence of…
Lattice bosons in a quasi-disordered environment
R. Ramakumar, A. N. Das
In this paper, we study non-interacting bosons in a disordered one-dimensional optical lattice in a harmonic potential. We consider the case of deterministic disorder produced by a…
Collapse dynamics of a - Bose-Einstein condensate
G. K. Chaudhary, R. Ramakumar
In this paper, we present a theoretical study of a two-component Bose-Einstein condensate composed of Ytterbium (Yb) isotopes in a three dimensional anisotropic harmonic potential.…
Two-step condensation of lattice bosons
R. Ramakumar, A. N. Das
We present a theoretical study of Bose-Einstein condensation in highly anisotropic harmonic traps. The bosons are considered to be moving in an optical lattice in an overall anisot…
Bose-Einstein condensate in a quartic potential: Static and Dynamic properties
G. K. Chaudhary, Amit K Chattopadhyay, R. Ramakumar
In this paper, we present a theoretical study of a Bose-Einstein condensate of interacting bosons in a quartic trap in one, two, and three dimensions. Using Thomas-Fermi approximat…
