Fourth- and fifth-order virial expansion of harmonically trapped fermions at unitarity
Y. Hou, K. J. Morrell, A. J. Czejdo +1
By generalizing our automated algebra approach from homogeneous space to harmonically trapped systems, we have calculated the fourth- and fifth-order virial coefficients of univers…
Virial coefficients of trapped and un-trapped three-component fermions with three-body forces in arbitrary spatial dimensions
A. J. Czejdo, J. E. Drut, Y. Hou +2
Using a coarse temporal lattice approximation, we calculate the first few terms of the virial expansion of a three-species fermion system with a three-body contact interaction in $…
The virial expansion of attractively interacting Fermi gases in 1D, 2D, and 3D, up to fifth order
Y. Hou, J. E. Drut
The virial expansion characterizes the high-temperature approach to the quantum-classical crossover in any quantum many-body system. Here, we calculate the virial coefficients up t…
Leading- and next-to-leading order semiclassical approximation to the first seven virial coefficients of spin-1/2 fermions across spatial dimensions
Y. Hou, A. Czejdo, J. DeChant +2
Following up on recent calculations, we investigate the leading- and next-to-leading order semiclassical approximation to the virial coefficients of a two-species fermion system wi…
