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…
