Abstract | Motivated by recent development in time-resolved angle-resolved photoemission spectroscopy (trARPES) for d-wave superconductors, we analyze the nonequilibrium relaxation dynamics of the laser pulse excited sample within the scenario of a two-temperature model. The main features reported in the trARPES technique may be understood within this phenomenological picture. The momentum dependencies of the excited quasiparticle density and the relaxation rate are associated with the dynamics of the nodal d-wave superconducting gap, and the fluence dependence of the relaxation rate is related to the recombination process of quasiparticles into Cooper pairs. |
