Quantum emulation of topological magneto-optical effects using ultracold atoms

open access: yesnpj Quantum Information, 2022
Magneto-optical effect is a fundamental but broad concept in magnetic mediums. Here we propose a scheme for its quantum emulation using ultracold atoms. By representing the light-medium interaction in the quantum-emulation manner, the artificial magneto ...

Research on Microstructure Characteristics of Welded Joint by Magneto-Optical Imaging Method

open access: yesMetals, 2022
This paper proposes an approach for analyzing the microstructure evolution of laser welding seam by magneto-optical imaging (MOI). The Faraday magneto-optical effect and magnetic domain theory are used to account for the MOI mechanism.

Revealing photonic Lorentz force as the microscopic origin of topological photonic states

open access: yesNanophotonics, 2020
Charged particles like electrons moving in a magnetic field encounter Lorentz force, which governs the formation of electronic topological edge states in quantum Hall effect systems. Here we show that photons transporting in magneto-optical materials and

Large ultrafast-modulated Voigt effect in noncollinear antiferromagnet Mn3Sn

open access: yesNature Communications, 2021
Mn3Sn is an anti-ferromagnetic material which displays a large magneto-optical Kerr effect, despite lacking a ferromagnetic moment. Here, the authors show that likewise, Mn3Sn, also presents a particularly large magneto-optical Voigt signal, with a ...
