Trapped Fermi gases
D. A. Butts, D. S. Rokhsar
We study the properties of a spin-polarized Fermi gas in a harmonic trap, using the semiclassical (Thomas-Fermi) approximation. Universal forms for the spatial and momentum distrib…
Topology and Nematic Ordering I: A Gauge Theory
Paul E. Lammert, Daniel S. Rokhsar, John Toner
We consider the weakly first order phase transition between the isotropic and ordered phases of nematics in terms of the behavior of topological line defects. Analytical and Monte…
Topology and Nematic Ordering II: Observable Critical Behavior
John Toner, Paul E. Lammert, Daniel S. Rokhsar
This paper is the second in a pair treating a new lattice model for nematic media. In addition to the familiar isotropic (I) and nematically ordered (N) phases, the phase diagram e…
Metallic screening and correlation effects in superconducting fullerenes
P. E. Lammert, D. S. Rokhsar, S. Chakravarty +2
We consider the frequency dependent Coulomb interaction between electrons in a molecular metal in the limit in which the conduction bandwidth is much less than the plasma frequency…
Holons in Chiral Spin-Liquids: Statistics and Pairing
D. M. Deaven, D. S. Rokhsar, A. Barbieri
We study Gutzwiller-projected variational wavefunctions for charged, spinless holon excitations in chiral spin liquids. We find that these states describe anyons, with a statistica…
