Lattice bosons in quartic confinement
R. Ramakumar, A. N. Das
We present a theoretical study of bose condensation of non-interacting bosons in finite lattices in quartic potentials in one, two, and three dimensions. We investigate dimensional…

Bose-Einstein condensation in tight-binding bands
R. Ramakumar, A. N. Das
We present a theoretical study of condensation of bosons in tight binding bands corresponding to simple cubic, body centered cubic, and face centered cubic lattices. We have analyz…
