Model Independent Probe of Variation of Cosmic Opacity with Redshift
Savita Gahlaut, Meetu Luthra
Cosmic opacity may vary spatially due to the inhomogeneous distribution of dust, its grain properties, and the efficiency of photon attenuation. In this work, we present a model in…
Supersolid in a one-dimensional optical lattice in the presence of a harmonic trap
Tapan Mishra, Sunethra Ramanan, Ramesh V. Pai +2
We study a system of ultra-cold atoms possessing long range interaction (e.g. dipole-dipole interaction) in a one dimensional optical lattice in the presence of a confining harmoni…
Supersolid and solitonic phases in one-dimensional Extended Bose-Hubbard model
Tapan Mishra, Ramesh V. Pai, S. Ramanan +2
We report our findings on quantum phase transitions in cold bosonic atoms in a one dimensional optical lattice using the finite size density matrix renormalization group method in…
Signatures of the superfluid to Mott insulator transition in cold bosonic atoms in a one dimensional optical lattice
S. Ramanan, Tapan Mishra, Meetu Sethi Luthra +2
We study the Bose-Hubbard model using the finite size density matrix renormalization group method. We obtain for the first time a complete phase diagram for a system in the presenc…
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…
