Dynamic Vortex Mass in Clean Fermi Superfluids and Superconductors

We calculate the dynamic vortex mass for clean Fermi superfluids including both $s$- and $d$-wave superconductors as a response to a vortex acceleration. Assuming a finite quasiparticle mean free time, the vortex mass appears to be a tensor with components depending on the quasiparticle relaxation time. The diagonal component dominates in the limit of long mean free time while the off-diagonal mass takes over in the moderately clean regime.
