Loss of superfluidity by fermions in the boson Hubbard model on an optical lattice
Roman M. Lutchyn, Sumanta Tewari, S. Das Sarma
The experimentally observed loss of superfluidity by introducing fermions to the boson Hubbard system on an optical lattice is explained. We show that the virtual transitions of th…

Boson Hubbard model with weakly coupled Fermions
R. M. Lutchyn, S. Tewari, S. Das Sarma
Using an imaginary-time path integral approach, we develop the perturbation theory suited to the boson Hubbard model, and apply it to calculate the effects of a dilute gas of spin-…

Anomalous Nernst effect from a chiral d-density wave state in underdoped cuprate superconductors
Chuanwei Zhang, Sumanta Tewari, Victor M. Yakovenko +1
We show that the breakdown of time-reversal invariance, confirmed by the recent polar Kerr effect measurements in the cuprates, implies the existence of an anomalous Nernst effect…
