Radio frequency spectroscopy of the attractive Hubbard model in a trap

Sanjoy Datta, Viveka Nand Singh, Pinaki Majumdar

Attractive interaction between fermions can lead to pairing and superfluidity in an optical lattice. In contrast to the `continuum', on a lattice the trap induced density variation…

Supersolidity in a Bose-Holstein model

Sanjoy Datta, Sudhakar Yarlagadda

We derive an effective d-dimensional Hamiltonian for a system of hard-core-bosons coupled to optical phonons in a lattice. At non-half-fillings, a superfluid-supersolid transition…

Quantum phase transition in Bose-Holstein model in two dimensions

Sanjoy Datta, Sudhakar Yarlagadda

We derive an effective d-dimensional Hamiltonian for a system of hard-core-bosons coupled to optical phonons in a lattice. Away from half-filling, we show that the presence of next…

Phase transition and phase diagram at a general filling in the spinless one-dimensional Holstein Model

Sanjoy Datta, Sudhakar Yarlagadda

Among the mechanisms for lattice structural deformation, the electron-phonon interaction mediated Peierls charge-density-wave (CDW) instability in single band low-dimensional syste…

Many-Polaron Effects in the Holstein Model

Sanjoy Datta, Arnab Das, Sudhakar Yarlagadda

We derive an effective polaronic interaction Hamiltonian, {\it exact to second order in perturbation}, for the spinless one-dimensional Holstein model. The small parameter is given…
