Correlation driven metallic and half-metallic phases in a band insulator
Soumen Bag, Arti Garg, H. R. Krishnamurthy
We demonstrate, using dynamical mean-field theory with the hybridization expansion continuous time quantum montecarlo impurity solver, a rich phase diagram with {\em correlation dr…

Is there a superconducting phase in the half-filled ionic Hubbard model ?
Anwesha Chattopadhyay, Soumen Bag, H. R. Krishnamurthy +1
We investigate the ionic Hubbard model (IHM) at half-filling in the limit of strong correlations and large ionic potential. The low energy effective Hamiltonian in this limit, obta…
