Global structure of Bose-Einstein condensates at high rotation: Beyond the lowest Landau level description
Gentaro Watanabe, C. J. Pethick
We study the global density profile of a rapidly rotating Bose-Einstein condensate in a harmonic trap with transverse frequency . By introducing an additional variationa…
Tensor Correlations and Pions in Dense Nuclear Matter
E. Olsson, C. J. Pethick
The study of tensor correlations and pions in dense matter in astronomical contexts has recently acquired renewed importance for a number of reasons. One is the discovery by Akmal,…
Kinetic Theory of Collective Modes in Atomic Clouds above the Bose-Einstein Transition Temperature
U. Al Khawaja, C. J. Pethick, H. Smith
We calculate frequencies and damping rates of the lowest collective modes of a dilute Bose gas confined in an anisotropic trapping potential above the Bose-Einstein transition temp…
Neutron Star Structure
C. J. Pethick, A. Akmal, V. R. Pandharipande +1
A review of properties of matter in the interior of neutron stars is given. Particular attention is paid to recent many-body theory calculations of the properties of dense matter.…
Bosons with attractive interactions in a trap: Is the ground state fragmented ?
Oe. Elgaroey, C. J. Pethick
Possible fragmentation of a Bose-Einstein condensate with negative scattering length is investigated using a simple two-level model. Our results indicate that fragmentation does no…
