Abstract
The coexistence of the universal transverse force and the non-universa l friction force on a topological singularity in a superfluid is shown here. Based on the BCS type microscopic theory, we explicitly evaluat e the quasiparticle contribution to the friction coefficient in a clea n fermionic superfluid, showing a new feature of logarithmic divergenc e.
