Effect of site dilution in the two-dimensional attractive Hubbard model
Saurabh Pradhan, G. Venketeswara Pai
We study the percolative superconducting transition as the density of randomly placed attractive centers grows in a host metal. Employing the Hubbard-Stratanovich transformation fo…
The Holstein-Hubbard Model at Half-filling : A Static Auxiliary Field Study
Saurabh Pradhan, G. Venketeswara Pai
We study the Holstein-Hubbard model at half filling to explore the ordered phases such as the charge density wave and antiferromagnet. The Coulomb interaction is rewritten in terms…
Onset of an Insulating Zero-Plateau Quantum Hall State in Graphene
Efrat Shimshoni, H. A. Fertig, G. Venketeswara Pai
We analyze the dissipative conductance of the zero-plateau quantum Hall state appearing in undoped graphene in strong magnetic fields. Charge transport in this state is assumed to…
Resistivity of Inhomogeneous Superconducting Wires
G. Venketeswara Pai, E. Shimshoni, N. Andrei
We study the contribution of quantum phase fluctuations in the superconducting order parameter to the low--temperature resistivity of a dirty and inhomogeneous superconducti…
Nonlinear Current of Strongly Irradiated Quantum Hall Gas
Assa Auerbach, G. Venketeswara Pai
Two dimensional electrons in weakly disordered high Landau levels are considered. The current-field response in the presence of a strong microwave field, is computed. The disordere…
Density wave and supersolid phases of correlated bosons in an optical lattice
Dmitry L. Kovrizhin, G. Venketeswara Pai, Subhasis Sinha
Motivated by the recent experiment on the Bose-Einstein condensation of Cr atoms with long-range dipolar interactions (Werner J. et al., Phys. Rev. Lett., 94 (2005) 183201),…
