Orbital order in Mott insulators of spinless p-band fermions
Erhai Zhao, W. Vincent Liu
A gas of strongly interacting spinless p-orbital fermionic atoms in 2D optical lattices is proposed and studied. Several interesting new features are found. In the Mott limit on a…
Self-consistent slave rotor mean field theory for strongly correlated systems
Erhai Zhao, Arun Paramekanti
Building on work by Florens and Georges, we formulate and study a self-consistent slave rotor mean field theory for strongly correlated systems. This approach views the electron, i…
Temperature dependent Fermi arcs in the normal state of the underdoped cuprate superconductors
A. Paramekanti, E. Zhao
Angle resolved photoemission experiments by Kanigel, et al (cond-mat/0605499) [Nature Physics 2, 447 (2006)] have made a remarkable observation that low energy electronic excitatio…
Excitations in correlated superfluids near a continuous transition into a supersolid
Erhai Zhao, Arun Paramekanti
We study a superfluid on a lattice close to a transition into a supersolid phase and show that a uniform superflow in the homogeneous superfluid can drive the roton gap to zero. Th…
