Abstract:

The sinh-Poisson equation describing two-dimensional steady state distributions of elements with a logarithmic interaction potential charged filaments executing guiding center motion quantized vortex lines or rotons is solved numerically. Multiple solutions are obtained for the case of negative temperatures. These have a simple thermodynamic interpretation which agrees with the results of numerical simulations. The results are related to numerical experiments and observations of vortex filaments in liquid He4.
