Complex Langevin and other approaches to the sign problem in quantum many-body physics
Casey E. Berger, Lukas Rammelmüller, Andrew C. Loheac +3
We review the theory and applications of complex stochastic quantization to the quantum many-body problem. Along the way, we present a brief overview of a number of ideas that eith…
Finite-temperature equation of state of polarized fermions at unitarity
Lukas Rammelmüller, Andrew C. Loheac, Joaquín E. Drut +1
We study in a nonperturbative fashion the thermodynamics of a unitary Fermi gas over a wide range of temperatures and spin polarizations. To this end, we use the complex Langevin m…
Polarized fermions in one dimension: density and polarization from complex Langevin calculations, perturbation theory, and the virial expansion
Andrew C. Loheac, Jens Braun, Joaquín E. Drut
We calculate the finite-temperature density and polarization equations of state of one-dimensional fermions with a zero-range interaction, considering both attractive and repulsive…
Third-order perturbative lattice and complex Langevin analyses of the finite-temperature equation of state of non-relativistic fermions in one dimension
Andrew C. Loheac, Joaquin E. Drut
We analyze the pressure and density equations of state of unpolarized non-relativistic fermions at finite temperature in one spatial dimension. For attractively interacting regimes…
Interaction of Molecular Oxygen with Hexagonally Reconstructed Au (001) Surface
Andrew Loheac, Andi Barbour, Vladimir Komanicky +6
Kinetics of molecular oxygen / Au (001) surface interaction has been studied at high temperature and near atmospheric pressures of O2 gas with in situ x-ray scattering measurements…
Thermal equation of state of polarized fermions in one dimension via complex chemical potentials
A. C. Loheac, J. Braun, J. E. Drut +1
We present a nonperturbative computation of the equation of state of polarized, attractively interacting, nonrelativistic fermions in one spatial dimension at finite temperature. W…
