Twisted coupled wire model for a moiré sliding Luttinger liquid

Yichen Hu, Yuanfeng Xu, Biao Lian

Recent experiments in twisted bilayer WTe revealed the existence of anisotropic Luttinger liquid behavior. To generically characterize such anisotropic twisted bilayer systems,…

Integrability of the fractional quantum Hall edge states

Yichen Hu, Biao Lian

We investigate the homogeneous chiral edge theory of the filling fractional quantum Hall state, which is parameterized by a Luttinger liquid velocity matrix and an electron…

Chiral Sachdev-Ye model: Integrability and chaos of anyons in 1+1d

Yichen Hu, Biao Lian

We construct and study a chiral Sachdev-Ye (SY) model consisting of chiral SU Wess-Zumino-Witten (WZW) models with current-current interactions among each other, which g…

Dihedral twist liquid models from emergent Majorana fermions

Jeffrey C. Y. Teo, Yichen Hu

We present a family of electron-based coupled-wire models of bosonic orbifold topological phases, referred to as twist liquids, in two spatial dimensions. All local fermion degrees…

Excitonic fractional quantum Hall hierarchy in Moiré heterostructures

Yves H. Kwan, Yichen Hu, Steven H. Simon +1

We consider fractional quantum Hall states in systems where two flat Chern number bands are labeled by an approximately conserved 'valley' index and interchanged by time…
