Breakdown of helical edge state topologically protected conductance in time-reversal-breaking excitonic insulators
Yan-Qi Wang, Michał Papaj, Joel E. Moore
Gapless helical edge modes are a hallmark of the quantum spin Hall effect. Protected by time-reversal symmetry, each edge contributes a quantized zero-temperature conductance quant…
Optical rotation in thin chiral/twisted materials and the gyrotropic magnetic effect
Yan-Qi Wang, Takahiro Morimoto, Joel E. Moore
The rotation of the plane of polarization of light passing through a non-magnetic material is known as natural optical activity or optical gyrotropy. The behavior of this effect in…
Boundary edge networks induced by bulk topology
Yan-Qi Wang, Joel E. Moore
We introduce an effective edge network theory to characterize the boundary topology of coupled edge states generated from various types of topological insulators. Two examples stud…
A Scaling Behavior of Bloch Oscillation in Weyl Semimetals
Yan-Qi Wang, Xiong-Jun Liu
We predict a linear logarithmical scaling law of Bloch oscillation dynamics in Weyl semimetals (WSMs), which can be applied to detect Weyl nodal points. Applying the semiclassical…
