Summary: This work theoretically and experimentally demonstrates that non-Hermitian perturbations around bound states in the continuum can lead to topologically nontrivial singularities of the scattering matrix that comply with charge conservation. The associated scattering matrix poles, zeros, and pole-zero pairs delineate extreme scattering events, including lasing, coherent perfect absorption, and absorber-lasers. The presented framework enables a recipe for generation, annihilation, and addition of these singularities in electric circuits, with potential for extreme scattering engineering across a broad range of the electromagnetic spectrum.

Summary: In this study, a new method for achieving robust asymmetric generation of acoustic vortex field through dual-layer metasurfaces is introduced. This is achieved by controlling the intrinsic topologic charges and the parity of geometry design. The underlying physics is contributed to the one-way process of orbital angular momentum transition ensured by the broken spatial symmetry and the external topologic charge from the vortex diffraction. The novel phenomenon is experimentally demonstrated, providing new routes to manipulate the asymmetric response of vortex fields and potential applications in passive OAM-based diodes.

Summary: Acoustic resonant cavities are crucial for modern acoustical systems, and the discovery of supercavity resonances with ultrahigh quality-factor resonances brings new possibilities for applications such as high-resolution acoustic sensors and acoustic lasers. The research proposes a new class of supercavity resonances and provides experimental evidence to support its existence. The findings demonstrate the robustness of these resonances to fabrication imperfection and suggest the potential for enhanced acoustic emission, filtering, and sensing.

Summary: This research presents a general method for constructing Friedrich-Wintgen (FW) BICs and accidental BICs in a coupled acoustic waveguide-resonator system. By adjusting the position of the attached waveguide, their characteristic modes can be arbitrarily engineered. Additionally, the study shows that these BICs are sustained in systems with shapes such as rectangles, ellipses, and rhomboids.

Summary: The article introduces a platform that allows for the spontaneous generation and active manipulation of an optical vortex-antivortex pair using an external field. By utilizing an aluminum/silicon dioxide/nickel/silicon dioxide multilayer structure, a gradient-thickness optical cavity is created, where the magneto-optic effects of the nickel layer affect the transition between different topological phases. The vortex-antivortex pairs in the reflected light by the device are generated through mathematical singularities in the generalized parameter space of the silicon dioxide layers and exhibit polarization-dependent and topology-dependent dynamics driven by external magnetic fields.

Summary: Cavity magnonics explores the interaction between magnons and confined electromagnetic fields, offering strong magnon-photon coupling and nonlinear behavior in microwave cavities. This field has the potential to be integrated into future quantum technologies. Magnetic optical resonators enhance the interaction between magnons and light, enabling magnon cooling and heating. The coupling between a magnon mode and a superconducting qubit in a microwave cavity allows for measurements in the single magnon limit.

Summary: Non-Hermitian photonic systems with loss and gain have attracted significant attention for their exceptional abilities in controlling the flow of light. In this study, we introduce asymmetry to a PT-symmetric system with perfectly balanced loss and gain, and reveal the mechanism of transition from a quasibound state to simultaneous coherent perfect absorption and lasing in a layered structure. We analyze two types of asymmetry (geometric and non-Hermitian) using the scattering matrix technique and characterize the effect of coherent perfect absorption-lasing associated with the quasibound state. The counter-intuitive loss-induced-lasing-like behavior is also observed under the non-Hermitian asymmetry. The reported features of non-Hermitian structures have great potential for sensing and lasing applications.

Summary: The study investigates the nonlinear properties in a dissipatively coupled cavity magnonic system, demonstrating bistable behaviors in the transmission spectra under high power excitation. The observed bistabilities are explained using a coupled oscillator model, revealing different characteristics and trigger conditions. This work highlights the potential applications in low power nonlinearity devices and enhanced anharmonicity sensors, as well as exploring non-Hermitian physics in the nonlinear regime of cavity magnonics.

Summary: In this study, the localization and delocalization of flat-band states in an acoustic cubic lattice are investigated theoretically and experimentally. The construction of flat-band states is found to depend only on the excitation pressures and coupling coefficients, which are frequency independent. The flat-band state can either spread into the whole lattice or be localized in a primitive cell, depending on the excitation frequency.

Summary: The paper demonstrates the origin, evolution, and application of topological phase singularity pairs (TPSPs) resulting from BICs in nonreciprocal and non-Hermitian systems. The nonreciprocity contributes to creating accidental BICs asymmetrically, each of which can split into TPSP with topological charges 11 in reflection phases by inserting loss. Criteria to predict both number and angular positions of asymmetric BICs are established, providing new opportunities in thermal science, magneto-optics, or topological metasurfaces.

Summary: This study demonstrates a method to achieve single-beam perfect absorption in a cavity magnonic device, with interference effects controlled by adjusting the strength and direction of an external magnetic field. The interference also produces a level attraction-like hybridization, showing that such hybridization can be realized surprisingly in a coherently coupled system.

Summary: Exceptional points, degeneracies in open wave systems, have been observed in photonics, acoustics, and electronics. In addition to resonant degeneracy, an absorbing exceptional point with distinct physical features can be realized by engineering degeneracies in the absorption spectrum of dissipative optical microcavities. The distinct scattering properties of an absorbing exceptional point provide opportunities for fundamental study and applications of non-Hermitian degeneracies.
