WebApr 12, 2024 · Optical bound states in the continuum (BICs) have enabled suppression of radiation loss in various photonic structures. However, their quality ( ) factors can be limited by the intrinsic absorption loss, if present. We propose a type of BICs in which both the radiation and absorption losses are suppressed. The underlying mechanism is based on ... WebNonetheless, for sufficiently strong interactions we observe bound states of these unconventional magnons which possess a non-diverging group velocity. By measuring the configurational mutual information between two disjoint intervals, we demonstrate the implications of the bound state formation on the entanglement dynamics of the system.
