Topological fragility and bilinear magnetoelectric resistance in gapless edge states
Cosimo Gorini, Matthieu Bard, Sophie Gueron +2
In time-reversal symmetric systems such as topological and higher-order topological insulators, 1D spin-momentum locked edge and hinge states are theoretically ``perfectly conducti…

Continuous correlated states and dual-flatness in a moiré heterostructure
Mohammed M. Al Ezzi, Na Xin, Yanmeng Shi +13
Many-body effects in condensed matter yield novel quantum states when the electronic density of states is enhanced. A vivid example is flat bands, which suppress kinetic energy and…

Low-Field Metal-Insulator Transition in AB-Stacked Bilayer Graphene
Amarnath Chakraborty, Aleksandr Rodin, Shaffique Adam +1
We investigate the interplay of in-plane magnetic and transverse electric fields in AB-stacked bilayer graphene. In prior work neglecting trigonal warping, we demonstrated that thi…
