Terahertz spin dynamics in rare-earth orthoferrites
Xinwei Li, Dasom Kim, Yincheng Liu +1
Recent interest in developing fast spintronic devices and laser-controllable magnetic solids has sparked tremendous experimental and theoretical efforts to understand and manipulat…
Keldysh space control of charge dynamics in a strongly driven Mott insulator
Xinwei Li, Honglie Ning, Omar Mehio +7
The fate of a Mott insulator under strong low frequency optical driving conditions is a fundamental problem in quantum many-body dynamics. Using ultrafast broadband optical spectro…
Physics-Guided and Physics-Explainable Recurrent Neural Network for Time Dynamics in Optical Resonances
Yingheng Tang, Jichao Fan, Xinwei Li +4
Understanding the time evolution of physical systems is crucial to revealing fundamental characteristics that are hidden in frequency domain. In optical science, high-quality reson…
Observation of Photoinduced Terahertz Gain in GaAs Quantum Wells: Evidence for Radiative Two-Exciton-to-Biexciton Scattering
X. Li, K. Yoshioka, Q. Zhang +9
We have observed photoinduced negative optical conductivity, or gain, in the terahertz frequency range in a GaAs multiple-quantum-well structure in a strong perpendicular magnetic…
Terahertz Faraday and Kerr rotation spectroscopy of BiSb films in high magnetic fields up to 30 Tesla
Xinwei Li, Katsumasa Yoshioka, Ming Xie +16
We report results of terahertz Faraday and Kerr rotation spectroscopy measurements on thin films of , an alloy system that exhibits a semimetal-to-top…
Multi-parameter estimation with multi-mode Ramsey interferometry
Xinwei Li, Jia-Hao Cao, Qi Liu +2
Estimating multiple parameters simultaneously is of great importance to measurement science and application. For a single parameter, atomic Ramsey interferometry (or equivalently o…
