A Chiral Superlattice Route to Spin-Split Topological Antiferromagnetism

Thao Dinh, Mengke Liu, Jian-Xiang Qiu +48

The interplay between chirality and magnetism is a profound topic, spanning particle physics, condensed matter, chemistry and origin of life. In this paper, we study this interplay…

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…
