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 frustration, associated with the breaking of particle-hole symmetry, harbors a rich phase diagram. Theoretical findings associated w…

Instability of Nagaoka State and Quantum Phase Transition via Kinetic Frustration Control
Prakash Sharma, Yang Peng, Donna N. Sheng +2
We investigate the Nagaoka-Thouless (NT) ferromagnetic instability in the strongly interacting - Hubbard model by continuously breaking particle-hole symmetry on a tunable s…
