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…
Theory of topological defects and textures in two-dimensional quantum orders with spontaneous symmetry breaking
Yan-Qi Wang, Chunxiao Liu, Yuan-Ming Lu
We consider two-dimensional (2d) quantum many-body systems with long-range orders, where the only gapless excitations in the spectrum are Goldstone modes of spontaneously broken co…
Structure of domain walls in chiral spin liquids
Yan-Qi Wang, Chunxiao Liu, Joel E. Moore
The chiral spin liquid is one of the canonical examples of a topological state of quantum spins coexisting with symmetry-breaking chiral order; its experimental realization has bee…
Minimal one-dimensional model of bad metal behavior from fast particle-hole scattering
Yan-Qi Wang, Roman Rausch, Christoph Karrasch +1
A strongly interacting plasma of linearly dispersing electron and hole excitations in two spatial dimensions (2D), also known as a Dirac fluid, can be captured by relativistic hydr…
Imaging gate-tunable Tomonaga-Luttinger liquids in 1H-MoSe mirror twin boundaries
Tiancong Zhu, Wei Ruan, Yan-Qi Wang +15
One-dimensional electron systems (1DESs) exhibit properties that are fundamentally different from higher-dimensional systems. For example, electron-electron interactions in 1DESs h…
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…
Dirac and topological phonons with spin-orbital entangled orders
Yan-Qi Wang, Xiong-Jun Liu
We propose to study novel quantum phases and excitations for a 2D spin-orbit (SO) coupled bosonic -orbital optical lattice based on the recent experiments. The orbital and spin…
A generic theory for Majorana zero modes in 2D superconductors
Cheung Chan, Lin Zhang, Ting Fung Jeffrey Poon +3
It is well known that non-Abelian Majorana zero modes (MZM) harbor at vortex cores in a topological superconductor, which can be realized in a 2D spin-orbit c…
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…
