Two-photon Interface of Nuclear Spins Based on the Opto-Nuclear Quadrupolar Effect
Haowei Xu, Changhao Li, Guoqing Wang +5
Photons and nuclear spins are two well-known building blocks in quantum information science and technology. Establishing an efficient interface between optical photons and nuclear…
Laser Cooling of Nuclear Magnons
Haowei Xu, Guoqing Wang, Changhao Li +5
The initialization of nuclear spin to its ground state is challenging due to its small energy scale compared with thermal energy, even at cryogenic temperature. In this Letter, we…
Nonlinear Nonreciprocal Photocurrents under Phonon Dressing
Haowei Xu, Hua Wang, Ju Li
Nonlinear optical (NLO) effects have attracted great interest recently. However, by far the computational studies on NLO use the independent particle approximation and ignore many-…
Abnormal Surface Nonlinear Optical Responses in Topological Materials
Haowei Xu, Hua Wang, Ju Li
Nonlinear optical (NLO) responses of topological materials are under active research in recent years. Yet by far, most studies focused on the bulk properties, whereas the surface e…
Colossal switchable photocurrents in topological Janus transition metal dichalcogenides
Haowei Xu, Hua Wang, Jian Zhou +3
Nonlinear optical properties, such as bulk photovoltaic effects, possess great potential in energy harvesting, photodetection, rectification, etc. To enable efficient light-current…
Light-Induced Static Magnetization: Nonlinear Edelstein Effect
Haowei Xu, Jian Zhou, Hua Wang +1
We theoretically and computationally demonstrate that static magnetization can be generated under light illumination via nonlinear Edelstein effect (NLEE). NLEE is applicable to se…
Giant Photonic Response of Mexican-hat Topological Semiconductors for Mid-infrared to THz Applications
Haowei Xu, Jian Zhou, Hua Wang +1
The mid-infrared (MIR), far-infrared (FIR) to terahertz (THz) frequencies are the least developed parts of the electromagnetic spectrum for applications. Traditional semiconductor…
Pure Spin Photocurrent in Non-centrosymmetric Crystals: Bulk Spin Photovoltaic Effect
Haowei Xu, Hua Wang, Jian Zhou +1
Spin current generators are critical components for spintronics-based information processing. In this work, we theoretically and computationally investigate the bulk spin photovolt…
