Polaron cross-overs and d-wave superconductivity in Hubbard-Holstein model
R. Ramakumar, A. N. Das
We present a theoretical study of superconductivity of polarons in the Hubbard-Holstein model. A residual kinematic interaction proportional to the square of the polaron hopping en…

Studies of bosons in optical lattices in a harmonic potential
R. Ramakumar, A. N. Das, S. Sil
We present a theoretical study of bose condensation and specific heat of non-interacting bosons in finite lattices in harmonic potentials in one, two, and three dimensions. We nume…
