Theory of quasi-one dimensional imbalanced Fermi gases
Erhai Zhao, W. Vincent Liu
We present a theory for a lattice array of weakly coupled one-dimensional ultracold attractive Fermi gases (1D `tubes') with spin imbalance, where strong intratube quantum fluctuat…
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…
BCS-BEC crossover on the two-dimensional honeycomb lattice
Erhai Zhao, Arun Paramekanti
The attractive Hubbard model on the honeycomb lattice exhibits, at half-filling, a quantum critical point (QCP) between a semimetal with massless Dirac fermions and an s-wave super…
Dynamics of spin transport in voltage-biased Josephson junctions
Erhai Zhao, J. A. Sauls
We investigate spin transport in voltage-biased spin-active Josephson junctions. The interplay of spin filtering, spin mixing, and multiple Andreev reflection leads to nonlinear vo…
