Trapped fermion mixtures with unequal masses: a Bogoliubov-de Gennes approach
M. Iskin, C. J. Williams
We use the Bogoliubov-de Gennes formalism to analyze the ground state phases of harmonically trapped two-species fermion mixtures with unequal masses. In the weakly attracting limi…
Vortex core states in superfluid Fermi-Fermi mixtures with unequal masses
M. Iskin
We analyze the vortex core states of two-species (mass imbalanced) superfluid fermion mixtures as a function of two-body binding energy in two dimensions. In particular we solve th…
Population imbalanced fermions in harmonically trapped optical lattices
M. Iskin, C. J. Williams
The attractive Fermi-Hubbard Hamiltonian is solved via the Bogoliubov-de Gennes formalism to analyze the ground state phases of population imbalanced fermion mixtures in harmonical…
Trapped p-wave superfluids: a local density approach
M. Iskin, C. J. Williams
The local density approximation is used to study the ground state superfluid properties of harmonically trapped p-wave Fermi gases as a function of fermion-fermion attraction stren…
Quantum phases of Fermi-Fermi mixtures in optical lattices
M. Iskin, C. A. R. Sa de Melo
The ground state phase diagram of Fermi-Fermi mixtures in optical lattices is analyzed as a function of interaction strength, population imbalance, filling fraction and tunneling p…
Trap-imbalanced fermion mixtures
M. Iskin, C. J. Williams
We analyze the ground state phases of two-component () population- and mass-balanced ( and $m_\uparrow = m_…
