Melting temperature shifts from quantum fluctuations in generalized Wigner crystals
Aman Kumar, Sogoud Sherif, Veit Elser +1
It is generally believed that quantum fluctuations collaborate with thermal fluctuations, effectively reducing transition temperatures (e.g. for melting of charge order). We show t…

Haerter-Shastry kinetic magnetism and metallicity in the triangular Hubbard model
Sogoud Sherif, Prakash Sharma, Aman Kumar +1
The fermionic Hubbard model, when combined with the ingredient of frustration, associated with the breaking of particle-hole symmetry, harbors a rich phase diagram. Aspects of theo…

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 f…
