Bypassing the Chiral Obstruction in Two-Dimensional Tensor Networks
Sen Niu, Rui-Zhen Huang
Gapped chiral phases pose an intrinsic obstruction to projected entangled pair state (PEPS) representations with finite bond dimension , which generically develop spurious long-…
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…
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…
Simulating chiral spin liquids with fermionic Projected Entangled Paired States
Sasank Budaraju, Didier Poilblanc, Sen Niu
Chiral Spin Liquids (CSL) based on spin-1/2 fermionic Projected Entangled Pair States (fPEPS) are considered on the square lattice. First, fPEPS approximants of Gutzwiller-projecte…
