Highly responsive ground state of PbTaSe${}_2$: structural phase transition and evolution of superconductivity under pressure

Udhara Kaluarachchi, Yuhang Deng, Matthew F. Besser +12

Transport and magnetic studies of PbTaSe${}_2$ under pressure suggest existence of two superconducting phases with the low temperature phase boundary at $\sim 0.25$ GPa that is defin…
