Repulsive Fermions in Optical Lattices: Phase separation versus Coexistence of Antiferromagnetism and d-Superfluidity
S. Y. Chang, S. Pathak, N. Trivedi
We investigate a system of fermions on a two-dimensional optical square lattice in the strongly repulsive coupling regime. In this case, the interactions can be controlled by laser…
Loss-induced phase separation and pairing for 3-species atomic lattice fermions
A. Privitera, I. Titvinidze, S. -Y. Chang +3
We study the physics of a three-component Fermi gas in an optical lattice, in the presence of a strong three-body constraint arising due to three-body loss. Using analytical and nu…
Radio Frequency Response of the Strongly Interacting Fermi Gases at Finite Temperatures
S. Y. Chang
The radio frequency spectrum of the fermions in the unitary limit at finite temperatures is characterized by the sum rule relations. We consider a simple picture where the atoms ar…
Equation of State and Phases of Polarized Unitary Fermi Gas
S. Y. Chang
The equation of state of the partially polarized two component Fermi gas at zero temperature in the unitary limit is computed by {\it ab initio} auxiliary field Monte Carlo method.…
Unitary Fermi Gas in a Harmonic Trap
S. Y. Chang, G. F. Bertsch
We present an {\it ab initio} calculation of small numbers of trapped, strongly interacting fermions using the Green's Function Monte Carlo method (GFMC). The ground state energy,…
Superfluid Pairing in the Three Component Fermi Gas
S. Y. Chang, V. R. Pandharipande
We present an analysis of the SU(3) symmetric model of the strongly interacting three component Fermi gas in the continuum space using quantum Monte Carlo techniques. Three body ef…
