Thermodynamics of spin-1/2 fermions on coarse temporal lattices using automated algebra

Autor: Morrell, K. J., Czejdo, A. J., Carter, N., Drut, J. E.

Recent advances in automated algebra for dilute Fermi gases in the virial expansion, where coarse temporal lattices were found advantageous, motivate the study of more general computational schemes that could be applied to arbitrary densities, beyond

Report

Fourth- and fifth-order virial expansion of harmonically trapped fermions at unitarity

Autor: Hou, Y., Morrell, K. J., Czejdo, A. J., Drut, J. E.

Publikováno v: Phys. Rev. Research 3, 033099 (2021)

By generalizing our automated algebra approach from homogeneous space to harmonically trapped systems, we have calculated the fourth- and fifth-order virial coefficients of universal spin-1/2 fermions in the unitary limit, confined in an isotropic ha

Thermodynamics of rotating quantum matter in the virial expansion

Autor: Berger, C. E., Morrell, K. J., Drut, J. E.

Publikováno v: Phys. Rev. A 102, 023309 (2020)

We characterize the high-temperature thermodynamics of rotating bosons and fermions in two- (2D) and three-dimensional (3D) isotropic harmonic trapping potentials. We begin by calculating analytically the conventional virial coefficients $b_n$ for al

Virial coefficients of trapped and un-trapped three-component fermions with three-body forces in arbitrary spatial dimensions

Autor: Czejdo, A. J., Drut, J. E., Hou, Y., McKenney, J. R., Morrell, K. J.

Publikováno v: Phys. Rev. A 101, 063630 (2020)

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 $d$ spatial dimensions, both in homogeneous space as well as in a harmo

Third- and fourth-order virial coefficients of harmonically trapped fermions in a semiclassical approximation

Autor: Morrell, K. J., Berger, C. E., Drut, J. E.

Publikováno v: Phys. Rev. A 100, 063626 (2019)

Using a leading-order semiclassical approximation, we calculate the third- and fourth-order virial coefficients of nonrelativistic spin-1/2 fermions in a harmonic trapping potential in arbitrary spatial dimensions, and as functions of temperature, tr
