Superfluid Mutual-friction Coefficients from Vortex Dynamics in the Two-dimensional Galerkin-truncated Gross-Pitaevskii Equation

Vishwanath Shukla, Marc Brachet, Rahul Pandit

We present algorithms for the ab-initio determination of the temperature ($T$) dependence of the mutual-friction coefficients $\alpha$ and ${\alpha }^{\prime }$ and the normal-fluid density ${\rho }_{\mathrm{n}}$…
