Imaging the Néel vector switching in the monolayer antiferromagnet MnPSe with strain-controlled Ising order
Zhuoliang Ni, A. V. Haglund, H. Wang +7
The family of monolayer two-dimensional (2D) materials hosts a wide range of interesting phenomena, including superconductivity, charge density waves, topological states and ferrom…
A re-examination of antiferroelectric PbZrO and PbHfO: an 80-atom structure
J. S. Baker, M. Paściak, J. K. Shenton +8
First principles density functional theory (DFT) simulations of antiferroelectric (AFE) PbZrO and PbHfO reveal a dynamical instability in the phonon spectra of their purpor…
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…
Temperature-driven Topological Phase Transition and Intermediate Dirac Semimetal Phase in ZrTe
B. Xu, L. X. Zhao, P. Marsik +6
We present an infrared spectroscopy study of ZrTe, which confirms a recent theoretical proposal that this material exhibits a temperature-driven topological quantum phase trans…
