Observation of polaritonic flat-band bound states in the continuum in a 2D magnet
Fuhuan Shen, Jiahao Ren, Zhiyi Yuan +5
Flat-band bound states in the continuum (BICs) are topological states with suppressed group velocity and robustness against radiation loss, offering a powerful platform for the exp…
Generalized Non-Hermitian Hamiltonian for Guided Resonances in Photonic Crystal Slabs
Viet Anh Nguyen, Hung Son Nguyen, Zhiyi Yuan +6
We develop a generalized non-Hermitian Hamiltonian formalism for guided resonances in photonic crystal slabs, derived directly from Maxwell's equations through a systematic guided-…
Hybridization of Non-Hermitian Topological Interface Modes
Yuhao Wang, Hai-Chau Nguyen, Zhiyi Yuan +5
We propose and experimentally demonstrate the hybridization of radiating topological interface states, analogous to Jackiw-Rebbi states but in gain media with radiation fields. Thi…
Micrometer-resolution fluorescence and lifetime mappings of CsPbBr nanocrystal films coupled with a TiO grating
Viet Anh Nguyen, Linh Thi Dieu Nguyen, Thi Thu Ha Do +15
Enhancing light emission from perovskite nanocrystal (NC) films is essential in light-emitting devices, as their conventional stacks often restrict the escape of emitted light. Thi…
