Coexisting localized and itinerant gapless excitations in a quantum spin liquid candidate 1T-TaS${}_2$

H. Murayama, Y. Sato, X. Z. Xing +6

To reveal the nature of elementary excitations in a quantum spin liquid (QSL), we measured low temperature thermal conductivity and specific heat of 1T-TaS${}_2$, a QSL candidate mat…
