Quasiparticle Relaxation Dynamics in URu${}_{2-x}$Fe${}_x$Si${}_2$ Single Crystals

Peter Kissin, Sheng Ran, Dylan Lovinger +5

We investigate quasiparticle relaxation dynamics in URu${}_{2-x}$Fe${}_x$Si${}_2$ single crystals using ultrafast optical-pump optical-probe (OPOP) spectroscopy as a function of temp…
