Observation of giant surface second harmonic generation coupled to nematic orders in the van der Waals antiferromagnet FePS
Zhuoliang Ni, Nan Huang, Amanda V. Haglund +2
Second harmonic generation has been applied to study lattice, electronic and magnetic proprieties in atomically thin materials. However, inversion symmetry breaking is usually requ…
Giant intrinsic anomalous terahertz Faraday rotation in the magnetic Weyl semimetal CoMnGa at room temperature
Xingyue Han, Anastasios Markou, Jonathan Stensberg +3
We report measurement of terahertz anomalous Hall conductivity and Faraday rotation in the magnetic Weyl semimetal CoMnGa thin films as a function of the magnetic field, temper…

The family of monolayer two-dimensional (2D) materials hosts a wide range of interesting phenomena, including superconductivity, charge density waves, topological states and ferrom…
Kondo physics in antiferromagnetic Weyl semimetal Mn3+xSn1-x films
Durga Khadka, T. R. Thapaliya, Sebastian Hurtado Parra +9
Topology and strong electron correlations are crucial ingredients in emerging quantum materials, yet their intersection in experimental systems has been relatively limited to date.…
Giant topological longitudinal circular photo-galvanic effect in the chiral multifold semimetal CoSi
Zhuoliang Ni, K. Wang, Y. Zhang +10
The absence of mirror symmetry, or chirality, is behind striking natural phenomena found in systems as diverse as DNA and crystalline solids. A remarkable example occurs when chira…
Linear and nonlinear optical responses in the chiral multifold semimetal RhSi
Zhuoliang Ni, B. Xu, M. A. Sanchez-Martinez +8
Chiral topological semimetals are materials that break both inversion and mirror symmetries. They host interesting phenomena such as the quantized circular photogalvanic effect (CP…
Optical signatures of multifold fermions in the chiral topological semimetal CoSi
B. Xu, Z. Fang, M. A. Sánchez-Martínez +12
We report the optical conductivity in high-quality crystals of the chiral topological semimetal CoSi, which hosts exotic quasiparticles known as multifold fermions. We find that th…
Large magneto-optical Kerr effect and imaging of magnetic octupole domains in an antiferromagnetic metal
Tomoya Higo, Huiyuan Man, Daniel B. Gopman +14
When a polarized light beam is incident upon the surface of a magnetic material, the reflected light undergoes a polarization rotation. This magneto-optical Kerr effect (MOKE) has…
Resonance-enhanced optical nonlinearity in the Weyl semimetal TaAs
Shreyas Patankar, Liang Wu, Baozhu Lu +10
While all media can exhibit first-order conductivity describing current linearly proportional to electric field, , the second-order conductivity, , relating current to…
Giant anisotropic nonlinear optical response in transition metal monopnictide Weyl semimetals
Liang Wu, S. Patankar, T. Morimoto +6
Although Weyl fermions have proven elusive in high-energy physics, their existence as emergent quasiparticles has been predicted in certain crystalline solids in which either inver…
