Origin and stability of generalized Wigner crystallinity in triangular moiré systems
Aman Kumar, Cyprian Lewandowski, Hitesh J. Changlani
Generalized Wigner crystals (GWC) on triangular moiré superlattices, formed from stacking two layers of transition metal chalcogenides, have been observed at multiple fractional fi…

Optical Absorption and Emission from Wannier-Stark Spectra of Moiré Superlattices
Vo Tien Phong, Francisco Guinea, Cyprian Lewandowski
Using a formalism based on the non-Abelian Berry connection, we explore quantum geometric signatures of Wannier-Stark spectra in two-dimensional superlattices. The Stark energy can…
