Phase separated charge density wave phase in two species extended Bose-Hubbard model
Tapan Mishra, B. K. Sahoo, Ramesh V. Pai
We study the quantum phase transitions in a two component bose-mixture in a one-dimensional optical lattice. The calculations have been performed in the framework of the extended B…
Phase diagram of a bosonic ladder with two coupled chains
Meetu Sethi Luthra, Tapan Mishra, Ramesh V. Pai +1
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-s…
Phases and Transitions in the Spin-1 Bose-Hubbard Model: Systematics of a Mean-field Theory
Ramesh V. Pai, K. Sheshadri, Rahul Pandit
We generalize the mean-field theory for the spinless Bose-Hubbard model to account for the different types of superfluid phases that can arise in the spin-1 case. In particular, ou…
Phase separation in a two species Bose mixture
T. Mishra, Ramesh V. Pai, B. P. Das
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(FSDMR…
