Transition of a prestine Mott insulator to a correlated Fermi liquid: Pressure-dependent optical investigations of a quantum spin liquid

Weiwu Li, Andrej Pustogow, Reizo Kato +1

Systematic pressure- and temperature-dependent infrared studies on the two-dimensional organic quantum spin-liquid ${\beta }^{\prime }$-EtMe${}_3$Sb[Pd(dmit)${}_2$]${}_2$ disclose the electronic…
