Quantized Superfluid Vortex Rings in the Unitary Fermi Gas
Aurel Bulgac, Michael McNeil Forbes, Michelle M. Kelley +2
In a recent article, Yefsah et al. [Nature 499, 426 (2013)] report the observation of an unusual excitation in an elongated harmonically trapped unitary Fermi gas. After phase impr…
Quantum Friction: Cooling Quantum Systems with Unitary Time Evolution
Aurel Bulgac, Michael McNeil Forbes, Kenneth J. Roche +1
We introduce a type of quantum dissipation -- local quantum friction -- by adding to the Hamiltonian a local potential that breaks time-reversal invariance so as to cool the system…
The temperature evolution of the shear viscosity in a unitary Fermi gas
Gabriel Wlazłowski, Piotr Magierski, Aurel Bulgac +1
We present an ab initio determination of the shear viscosity for the unitary Fermi gas based on finite temperature quantum Monte Carlo (QMC) calculations and the Kubo linear-respon…
