Ultracold Fermion Cooling Cycle using Heteronuclear Feshbach Resonances
M. A. Morales, N. Nygaard, J. E. Williams +1
We consider an ideal gas of Bose and Fermi atoms in a harmonic trap, with a Feshbach resonance in the interspecies atomic scattering that can lead to formation of fermionic molecul…
Comments on the Discrete Variable Representation
Barry I. Schneider, Nicolai Nygaard
We discuss the application of the Discrete Variable Representation to Schrödinger problems which involve singular Hamiltonians. Unlike recent authors who invoke transformations to…
Vortex line in a neutral finite-temperature superfluid Fermi gas
N. Nygaard, G. M. Bruun, B. I. Schneider +2
The structure of an isolated vortex in a dilute two-component neutral superfluid Fermi gas is studied within the context of self-consistent Bogoliubov-de Gennes theory. Various the…
Microscopic Structure of a Vortex Line in a Superfluid Fermi Gas
N. Nygaard, G. M. Bruun, C. W. Clark +1
The microscopic properties of a single vortex in a dilute superfluid Fermi gas at zero temperature are examined within the framework of self-consistent Bogoliubov-de Gennes theory.…
