Giant enhancement of the transverse magneto-optical Kerr effect in etchless bismuth-substituted yttrium iron garnet empowered by quasi-bound states in the continuum

Autor: Tang, Qin, Zhang, Dandan, Xiao, Shuyuan, Qin, Meibao, He, Jizhou, Liu, Tingting, Liao, Qinghua, Yu, Tianbao

Here, we propose an etchless bismuth-substituted yttrium iron garnet layer assisted by a one-dimensional resonant grating waveguide to enhance transverse magneto-optical Kerr effect (TMOKE) via the excitation of quasi-bound state in the continuum. Th

A Channel to Form Fast-spinning Black Hole-Neutron Star Binary Mergers as Multimessenger Sources. II. Accretion-induced Spin-up

Autor: Wang, Zhen-Han-Tao, Hu, Rui-Chong, Qin, Ying, Zhu, Jin-Ping, Zhang, Bing, Yi, Shuang-Xi, Tang, Qin-Wen, Shu, Xin-Wen, Lyu, Fen, Liang, En-Wei

In this work, we investigate an alternative channel for the formation of fast-spinning black hole-neutron star (BHNS) binaries, in which super-Eddington accretion is expected to occur in accreting BHs during the stable mass transfer phase within BH-s

Enhancing Faraday and Kerr rotations based on toroidal dipole mode in an all-dielectric magneto-optical metasurface

Autor: Tang, Qin, Zhang, Dandan, Liu, Tingting, Liu, Wenxing, Liao, Qinghua, He, Jizhou, Xiao, Shuyuan, Yu, Tianbao

Publikováno v: Optics Letters 48 (13), 3451-3454 (2023)

The magneto-optical Faraday and Kerr effects are widely used in modern optical devices. In this letter, we propose an all-dielectric metasurface composed of perforated magneto-optical thin films, which can support the highly confined toroidal dipole

Cataloguing MoSi$_2$N$_4$ and WSi$_2$N$_4$ van der Waals Heterostructures: An Exceptional Material Platform for Excitonic Solar Cell Applications

Autor: Tho, Che Chen, Yu, Chenjiang, Tang, Qin, Wang, Qianqian, Su, Tong, Feng, Zhuoer, Wu, Qingyun, Nguyen, C. V., Ong, Wee-Liat, Liang, Shi-Jun, Guo, San-Dong, Cao, Liemao, Zhang, Shengli, Yang, Shengyuan A., Ang, Lay Kee, Wang, Guangzhao, Ang, Yee Sin

Two-dimensional (2D) materials van der Waals heterostructures (vdWHs) provides a revolutionary route towards high-performance solar energy conversion devices beyond the conventional silicon-based pn junction solar cells. Despite tremendous research p
