Quasi-thermalization of collisionless particles in quadrupole potentials
Johnathan Lau, Olga Goulko, Thomas Reimann +4
We analyze several puzzling features of a recent experiment with a noninteracting gas of atoms in a quadrupole trap. After an initial momentum kick, the system reaches a stationary…
Collective modes of an imbalanced unitary Fermi gas
Johannes Hofmann, Frédéric Chevy, Olga Goulko +1
We study theoretically the collective mode spectrum of a strongly imbalanced two-component unitary Fermi gas in a cigar-shaped trap, where the minority species forms a gas of polar…
Dark Continuum in the Spectral Function of the Resonant Fermi Polaron
Olga Goulko, Andrey S. Mishchenko, Nikolay Prokof'ev +1
We present controlled numerical results for the ground state spectral function of the resonant Fermi polaron in three dimensions. We establish the existence of a "dark continuum"--…
Numerical study of the unitary Fermi gas across the superfluid transition
Olga Goulko, Matthew Wingate
We present results from Monte Carlo calculations investigating the properties of the homogeneous, spin-balanced unitary Fermi gas in three dimensions. The temperature is varied acr…
Analog Simulation of Weyl Particles with Cold Atoms
Daniel Suchet, Mihail Rabinovic, Thomas Reimann +7
We study theoretically, numerically, and experimentally the relaxation of a collisionless gas in a quadrupole trap after a momentum kick. The non-separability of the potential enab…
Boltzmann equation simulation for a trapped Fermi gas of atoms
Olga Goulko, Frédéric Chevy, Carlos Lobo
The dynamics of an interacting Fermi gas of atoms at sufficiently high temperatures can be efficiently studied via a numerical simulation of the Boltzmann equation. In this work we…
Collision of two spin polarized fermionic clouds
Olga Goulko, Frédéric Chevy, Carlos Lobo
We study the collision of two spin polarized Fermi clouds in a harmonic trap using a simulation of the Boltzmann equation. As observed in recent experiments we find three distinct…
The imbalanced Fermi gas at unitarity
Olga Goulko, Matthew Wingate
Lattice field theory is a useful tool for studying strongly interacting theories in condensed matter physics. A prominent example is the unitary Fermi gas: a two-component system o…
Thermodynamics of balanced and slightly spin-imbalanced Fermi gases at unitarity
Olga Goulko, Matthew Wingate
In this paper we present a Monte Carlo calculation of the critical temperature and other thermodynamic quantities for the unitary Fermi gas with a population imbalance (unequal num…
Monte Carlo study of a Fermi gas with infinite scattering length
Olga Goulko, Matthew Wingate
The Fermi gas at unitarity is a particularly interesting system of cold atoms, being dilute and strongly interacting at the same time. It can be studied non-perturbatively with Mon…
