On the correct formula for the lifetime broadened superconducting density of states

Bozidar Mitrovic, Lee A. Rozema

We argue that the well known Dynes formula [Dynes R C {\it et al.} 1978 {\it Phys. Rev. Lett.} {\bf 41} 1509] for the superconducting quasiparticle density of states, which tries t…
