Incoherent topological defect recombination dynamics in TbTe_3

Abstract

We study the incoherent recombination of topological defects created during a rapid quench of a charge-density-wave system through the electronic ordering transition. Using a specially devised 3-pulse femtosecond optical spectroscopy technique we follow the evolution of the order parameter over a wide range of timescales. By careful consideration of thermal processes we can clearly identify intrinsic topological defect annihilation processes on a timescale ~30 ps and find a signature of extrinsic defect-dominated relaxation dynamics is found to occurring on longer timescales.
