    Coherent optical control of polarization with a critical metasurface by Kang, Ming, Chong, Yi Dong

    Published 2015
    “…The system can be described by a non-Hermitian effective Hamiltonian which is parity-time (PT) symmetric, although there is no actual gain present; perfect polarization conversion occurs at the eigenfrequencies of this Hamiltonian, and the polarization rotating behavior occurs at the critical point of its PT-breaking transition.…”

    Proposal for observing Yang-Lee criticality in Rydberg atomic arrays by Shen, Ruizhe, Chen, Tianqi, Aliyu, Mohammad Mujahid, Qin, Fang, Zhong, Yin, Loh, Huanqian, Lee, Ching Hua

    Published 2023
    “…They play an important role in understanding non-Hermitian phase transitions in many-body physics, as well as characterizing the corresponding nonunitary criticality. Even though such partition function zeroes have been measured in dynamical experiments where time acts as the imaginary control field, experimentally demonstrating such YLES criticality with a physical imaginary field has remained elusive due to the difficulty of physically realizing non-Hermitian many-body models. …”

    Published 2014
    “…Coherent perfect absorption refers to the complete absorption of symmetric plane waves incident on opposite sides of the system, due to critical coupling into the dissipative degrees of freedom. …”

    Large in-plane asymmetric spin angular shifts of a light beam near the critical angle by Zhou, Xinxing, Xie, Linguo, Ling, Xiaohui, Cheng, Shijia, Zhang, Zhiyou, Luo, Hailu, Sun, Handong

    Published 2020
    “…In this Letter, we theoretically propose and experimentally verify a simple method for obtaining large and asymmetric in-plane spin angular shifts when an arbitrary linearly polarized beam reflects near the critical angle (for total internal reflection). The universal expressions of spatial and angular shifts are deduced. …”

    Critical role of chloride in organic ammonium spacer on the performance of Low-dimensional Ruddlesden-Popper perovskite solar cells by Chen, Haoran, Xia, Yingdong, Wu, Bo, Liu, Feng, Niu, Tingting, Chao, Lingfeng, Xing, Guichuan, Sum, Tze Chien, Chen, Yonghua, Huang, Wei

    Published 2020
    “…However, further improvements require a fundamental understanding on the components functionality in LDRP perovskites, e.g., bulky organic ammonium spacer and halogen ions, which are critical for designing efficient LDRP PSCs. Here, we report the critical role of the chloride that are derived from halogenated organic ammonium salts on the LDRP perovskite film crystallization, growth, opto-electric properties, and device performance. …”

    Critical behavior and the absence of glass state in ferromagnetic La0.7Ca0.3CoO3 nanowires by Wang, Yang, Fan, Hong Jin

    Published 2013
    “…The thermopower and specific heat results indicate that there exist enhanced spin and/or orbital fluctuations in the nanowires that could be responsible for the absence of the glass state. Critical behavior analysis shows that the nanowires fall into a three-dimensional Heisenberg ferromagnet class.…”
