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…
Excitation Spectra of Correlated Lattice Bosons in a Confining Trap
Dmitry L. Kovrizhin, G. Venketeswara Pai, Subhasis Sinha
We consider ultracold bosonic atoms in an optical lattice with an external trapping potential. To study the excitation energies of the resulting Bose-Hubbard model, we develop a me…
