Coulomb gas sum rules for vortex-pair fluctuations in 2D superfluids
Mingyu Fan, Gary A. Williams, Karla Galdamez +1
Vortex fluctuations above and below the critical Kosterlitz-Thouless (KT) transition temperature are characterized using simulations of the 2D XY model. The net winding number of v…
Fundamental connection between temperature-quenched 2D superfluids and 2D quantum turbulence
Gary A. Williams
There is a fundamental connection between temperature-quenched 2D superfluids and 2D quantum turbulence: the mechanism responsible for the decay of the vorticity after the quench i…
Vortex-loop calculation of the specific heat of superfluid He under pressure
Andrew Forrester, Gary A. Williams
Vortex-loop renormalization is used to compute the specific heat of superfluid He near the lambda point at various pressures up to 26 bars. The input parameters are the the pre…
Dynamics of the forward vortex cascade in two-dimensional quantum turbulence
Andrew Forrester, Gary A. Williams
The dynamics of the forward vortex cascade in 2D turbulence in a superfluid film is investigated using analytic techniques. The cascade is formed by injecting pairs with the same i…
Comment on "Vortex String Formation in a 3D U(1) Temperature Quench"
Gary A. Williams
Comment on "Vortex String Formation in a 3D U(1) Temperature Quench" by N. D. Antunes, L. M. A. Bettencourt, and W. H. Zurek, Phys. Rev. Lett. 82, 2824 (1999).
Non-universal Casimir Effect in Saturated Superfluid He Films at T
John B. S. Abraham, Gary A. Williams, Konstantin Penanen
Measurements of Casimir effects in He films in the vicinity of the bulk superfluid transition temperature have been carried out, where changes in the film thickness and t…
