at Ultralow Temperatures

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.
