Quantum Transport of Small-Angle Twisted Bilayer WTe<sub>2</sub> at Ultralow Temperatures

ORAL

Abstract

Various intriguing quantum phases have been observed in monolayer WTe2, such as superconductivity, quantum spin Hall states and an excitonic insulating state. In small angle twist bilayer WTe2 (tWTe2), experiments show that an anisotropic 2D phase mimicking a Luttinger liquid emerges. Due to its strong electron correlations and unique Moiré superlattices, tWTe2 provides a new platform to study novel states beyond the Fermi liquid description, thus calling for more comprehensive studies at ultralow temperature. In this talk, I will present our recent efforts on transport studies of tWTe2 system at ultralow temperatures with various tuning knobs such as the twist angle.
