Zero temperature optical conductivity of ultra-clean Fermi liquids and superconductors
A. Rosch, P. C. Howell
We calculate the low-frequency optical conductivity sigma(w) of clean metals and superconductors at zero temperature neglecting the effects of impurities and phonons. In general, t…

Relaxation of Hot Quasiparticles in a d-Wave Superconductor
P. C. Howell, A. Rosch, P. J. Hirschfeld
Motivated by recent pump-probe experiments we consider the processes by which "hot" quasiparticles produced near the antinodes of a d-wave superconductor can relax. We show that in…
