Effects of a dilute gas of fermions on the superfluid-insulator phase diagram of the Bose-Hubbard model
Sumanta Tewari, Roman M. Lutchyn, S. Das Sarma
Building on the work of Fisher et al. (Phys. Rev. B 40, 546 (1989)), we develop a framework for perturbation theory in the Bose-Hubbard model and apply it to calculate the effects…

Effects of quasiparticle ambipolarity on the Nernst effect in underdoped cuprate superconductors
Sumanta Tewari, Chuanwei Zhang
We consider the Nernst effect in the normal state of the underdoped cuprate superconductors, where recent quantum oscillation experiments have indicated the existence of Fermi surf…
