Superconducting quantum criticality in monolayer WTe<sub>2</sub>

ORAL

Abstract

The study of quantum phase transitions in strongly correlated electron systems is of great interest due to the associated quantum critical behaviors. Among different kinds of material systems, tungsten ditelluride (WTe2) is a unique 2D semimetal, which exhibits quantum spin Hall insulator (QSHI), gate-tuned superconductivity, excitonic insulator, and ferroelectricity in a single material. In this talk, I will present the thermoelectric measurement of the QSHI to superconductor transition in monolayer WTe2. Our findings highlight monolayer WTe2 as a 2D model platform for investigating novel superconducting quantum criticality.
