  • Landau’s major contribution to physics a brief overview 
    Sivaram, C; Arun, K (South Asian Publisher, 2009-06)
    Lev Davidovich Landau was arguably one of the greatest and most versatile physicists. His work spans a very wide range and has had a considerable impact on ail areas of physics including condensed matter physics, ...
  • Phase diagram of a bosonic ladder with two coupled chains 
    Sethi Luthra, M; Mishra, T; Pai, R. V; Das, B. P (American Physical Society, 2008-10)
    We study a bosonic ladder with two coupled chains using the finite size density matrix renormalisation group method. We show that in a commensurate bosonic ladder the critical on-site interaction ($U_C$) for the superfluid ...
  • Phase separation in a two species Bose mixture 
    Mishra, T; Pai Ramesh, V; Das, B. P (The American Physical Society, 2007-07)
    We study the ground state quantum phase diagram for a two species Bose mixture in a one-dimensional optical lattice using the finite size density matrix renormalization group(FSDMRG) method. We discuss our results for ...
  • Quasiadiabatic dynamics of ultracold bosonic atoms in a one-dimensional optical superlattice 
    Dhar, A; Rossini, D; Das, B. P (The American Physical Society, 2015-09)
    We study the quasiadiabatic dynamics of a one-dimensional system of ultracold bosonic atoms loaded in an optical superlattice. Focusing on a slow linear variation in time of the superlattice potential, the system is driven ...
  • Three-body on-site interactions in ultracold bosonic atoms in optical lattices and superlattices 
    Singh, M; Dhar, A; Mishra, T; Pai, R. V; Das, B. P (American Physical Society, 2012-05)
    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-site interactions. In this paper, we analyze ...
