Topology and geometry under the nonlinear electromagnetic spotlight
Qiong Ma, Adolfo G. Grushin, Kenneth S. Burch
For many materials, a precise knowledge of their dispersion spectra is insufficient to predict their ordered phases and physical responses. Instead, these materials are classified…
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…
Strong bulk photovoltaic effect in chiral crystal in the visible spectrum
Yang Zhang, Fernando de Juan, Adolfo G. Grushin +2
Structurally chiral materials hosting multifold fermions with large topological number have attracted considerable attention because of their naturally long surface Fermi arcs and…
Spectral and optical properties of AgAu(Se,Te) and dark matter detection
Miguel-Ángel Sánchez-Martínez, Iñigo Robredo, Arkaitz Bidauzarraga +4
In this work we study the electronic structure of AgAuSe and AgAuTe, two chiral insulators whose gap can be tuned through small changes in the lattice param…
