Symmetry-Resolved Second Harmonic Generation in Quantum and Functional Materials
Xiaoyu Guo, Chang Jae Roh, Youngjun Ahn
Second harmonic generation (SHG) has evolved from a probe of noncentrosymmetric crystals into a symmetry-resolved optical method for identifying order parameters in quantum and fun…
Intertwined polar, chiral, and ferro-rotational orders in a rotation-only insulator
Weizhe Zhang, June Ho Yeo, Xiaoyu Guo +8
Intertwined orders refer to strongly coupled and mutually dependent orders that coexist in correlated electron systems, often underpinning key physical properties of the host mater…
Progress and Prospects in Two-Dimensional Magnetism of van der Waals Materials
Youngjun Ahn, Xiaoyu Guo, Suhan Son +2
Two-dimensional (2D) magnetism in van der Waals (vdW) atomic crystals and moiré superlattices has emerged as a topic of tremendous interest in the fields of condensed matter physic…
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…
