Thermodynamic-Limit Evidence for Chiral Superconductivity Induced by Doping Chiral Topological Phases
Sen Niu, D. N. Sheng, Yang Peng
The emergence of superconductivity from doping strongly correlated chiral topological phases in purely repulsive two-dimensional fermionic systems is a problem of broad and fundame…
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…
Quantum anomalous Hall effects and emergent Hall ferromagnets at fractional filling of helical trilayer graphene
Sen Niu, Jason Alicea, D. N. Sheng +1
Helical trilayer graphene realizes a versatile moiré system for exploring correlated topological states emerging from high Chern bands. Motivated by recent experimental observation…
Quantum phase diagram and non-abelian Moore-Read state in double twisted bilayer graphene
Sen Niu, Yang Peng, D. N. Sheng
Experimental realizations of Abelian fractional Chern insulators (FCIs) have demonstrated the potentials of moiré systems in synthesizing exotic quantum phases. Remarkably, twisted…
Topological quantum phase transitions driven by a displacement field in the twisted MoTe2 bilayers
Prakash Sharma, Yang Peng, D. N. Sheng
We study twisted bilayer MoTe systems at fractional fillings of the lowest hole band under an applied out-of-plane displacement field. By employing exact diagonalization in fin…
Thermoelectric response and entropy of fractional quantum Hall systems
D. N. Sheng, Liang Fu
We study thermoelectric transport properties of fractional quantum Hall systems based on exact diagonalization calculation. Based on the relation between thermoelectric response an…
