An unconventional deformation of the nonrelativistic spin-1/2 Fermi gas
Vimal Palanivelrajan, Joaquín E. Drut
We explore a generalization of nonrelativistic fermionic statistics that interpolates between bosons and fermions, in which up to particles may occupy a single-particle state.…
Thermodynamics of spin-1/2 fermions on coarse temporal lattices using automated algebra
K. J. Morrell, A. J. Czejdo, N. Carter +1
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 comp…
Calculating and resumming the classical virial expansion using automated algebra
Aaron M. Miller, Joaquín E. Drut
Using schematic model potentials, we calculate exactly the virial coefficients of a classical gas up to sixth order and use them to assess the convergence properties of the virial…
A lattice pairing-field approach to ultracold Fermi gases
Florian Ehmann, Joaquín E. Drut, Jens Braun
We develop a pairing-field formalism for ab initio studies of non-relativistic two-component fermions on a -dimensional spacetime lattice. More specifically, we focus on…
Toward an automated-algebra framework for high orders in the virial expansion of quantum matter
Aleks J. Czejdo, Joaquin E. Drut, Yaqi Hou +1
The virial expansion provides a non-perturbative view into the thermodynamics of quantum many-body systems in dilute regimes. While powerful, the expansion is challenging as calcul…
Pairing patterns in polarized unitary Fermi gases above the superfluid transition
Felipe Attanasio, Lukas Rammelmüller, Joaquín E. Drut +1
We non-perturbatively study pairing in the high-temperature regime of polarized unitary two-component Fermi gases by extracting the pair-momentum distribution and shot-noise correl…
