Perturbative renormalization group approach to magic-angle twisted bilayer graphene using topological heavy fermion model
Yi Huang, Yang-Zhi Chou, Sankar Das Sarma
We develop a perturbative renormalization group (RG) theory for the topological heavy fermion (THF) model, describing magic-angle twisted bilayer graphene (MATBG) as an emergent An…
Apparent inconsistency between Streda formula and Hall conductivity in reentrant integer quantum anomalous Hall effect in twisted MoTe
Yi Huang, Seth Musser, Jihang Zhu +2
Recent experiments in twisted bilayer MoTe (tMoTe) have uncovered a rich landscape of correlated phases. In this work, we investigate the reentrant integer quantum anomalou…
In-plane magnetic field-induced orbital FFLO superconductivity in twisted WSe homobilayers
Jihang Zhu, Yang-Zhi Chou, Yi Huang +1
We theoretically predict the in-plane magnetic field-induced orbital Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) superconducting states in twisted WSe homobilayers (tWSe), focu…
Integer Quantum Hall Effect: Disorder, temperature, floating, and plateau width
Stuart Yi-Thomas, Yi Huang, Jay D. Sau +1
We theoretically consider disorder and temperature effects on the integer quantum Hall effect (IQHE) using a variety of distinct and complementary analytical and numerical techniqu…
Reducing disorder in Ge quantum wells by using thick SiGe barriers
Davide Costa, Lucas E. A. Stehouwer, Yi Huang +4
We investigate the disorder properties of two-dimensional hole gases in Ge/SiGe heterostructures grown on Ge wafers, using thick SiGe barriers to mitigate the influence of the semi…
