Electric quadrupole second harmonic generation revealing dual magnetic orders in a magnetic Weyl semimetal
Youngjun Ahn, Xiaoyu Guo, Rui Xue +4
Broken symmetries and electronic topology are nicely manifested together in the second order nonlinear optical responses from topologically nontrivial materials. While second order…
"Extraordinary" Phase Transition Revealed in a van der Waals Antiferromagnet
Xiaoyu Guo, Wenhao Liu, Jonathan Schwartz +12
While the surface-bulk correspondence has been ubiquitously shown in topological phases, the relationship between surface and bulk in Landau-like phases is much less explored. Theo…
Endotaxial Stabilization of 2D Charge Density Waves with Long-range Order
Suk Hyun Sung, Nishkarsh Agarwal, Ismail El Baggari +10
Charge density waves are emergent quantum states that spontaneously reduce crystal symmetry, drive metal-insulator transitions, and precede superconductivity. In low-dimensions, di…
Backscattering-free edge states below all bands in two-dimensional auxetic media
Wenting Cheng, Kai Qian, Nan Cheng +3
Unidirectional and backscattering-free propagation of sound waves is of fundamental interest in physics, and highly sought-after in engineering. Current strategies utilize topologi…
Topologically Protected Exceptional Points and Reentrant Phase in an Exact Ternary Model
Chulwon Lee, Kai Zhang, Jinyan Miao +2
In open, driven systems where parity-time symmetry is preserved, phenomena that defy conventional wisdom emerge near exceptional points, promising advances in photonics. While most…
On the effects of strain, defects, and interactions on the topological properties of HfTe5
Na Hyun Jo, Omar A. Ashour, Zhixue Shu +7
Topological insulators are characterized by spin-momentum-locked massless surface states which are robust under various perturbations. Manipulating such surface states is a topic o…
