Detailed optical spectroscopy of the hybridization gap and the hidden order transition in high quality URu${}_2$Si${}_2$ single crystals

N. Bachar, D. Stricker, S. Muleady +4

We present a detailed temperature and frequency dependence of the optical conductivity measured on clean high quality single crystals of URu${}_2$Si${}_2$ of $ac$- and $ab$-plane s…
