Interplay between Quantum Metric and Hybridized Collective Mode in Flat-Band Superfluids
Yi Liu, Mingyan Wang, Penghui Hu +1
We investigate collective excitations in flat-band superfluids by incorporating the coupled dynamics of pairing (phase and amplitude) and density fluctuations. We demonstrate that…

Observation of Chiral Bound States in the Continuum in Self-biased Magneto-optical Photonic Crystals
Maohua Gong, Qiutong Zhen, Yujie Tang +5
Chiral bound states in the continuum (BICs) are confined photonic modes with infinite quality factors and chiral response, offering significant potential for chiral optics. Althoug…
