The interaction-sensitive states of a trapped two-component ideal Fermi gas and application to the virial expansion of the unitary Fermi gas
Shimpei Endo, Yvan Castin
We consider a two-component ideal Fermi gas in an isotropic harmonic potential. Some eigenstates have a wavefunction that vanishes when two distinguishable fermions are at the same…

The third virial coefficient of a two-component unitary Fermi gas across an Efimov-effect threshold
Chao Gao, Shimpei Endo, Yvan Castin
We consider a mixture of two single-spin-state fermions with an interaction of negligible range and infinite -wave scattering length. By varying the mass ratio across $α_c…
