Quantum phases and spin liquid properties of 1T-TaS2

Abstract Quantum materials exhibiting magnetic frustration are connected to diverse phenomena, including high T c superconductivity, topological order, and quantum spin liquids (QSLs). A QSL is a quantum phase (QP) related to a quantum-entangled fluid-like state of matter. Previous experiments on QS...
