Strong coupling between magnons and Anderson-localized microwave photons

Sun Pei-cheng, Qi Hong, Zong-Heng Meng, Xin Zhang et autres

Anderson localization turns disorder into mirror-free wave confinement. When such localized modes couple strongly to a tunable collective excitation, the disorder landscape can become a resource for light–matter control. Here, we demonstrate strong coupling between the Kittel magnon of a yttrium iron …

Pulmonary mRNA-LNP vaccines for rapid and durable protection against bacterial infection

Anqi Wei, Yu Miao, Zhou Yuan, Guanghui Li et autres

Pulmonary bacterial infections remain a major clinical challenge. Although vaccination reduces infection rates and mortality, the vulnerable post-vaccination immunity gap can still result in infection and vaccine failure. In addition, effective vaccines are unavailable for many clinically important bacterial pathogens. Here, we …

Transient coherent perfect absorption enables efficient wireless power transfer

Liang Hu, Han Zhang, Shengyu Hu, Kejia Zhu et autres

Abstract Coherent perfect absorption (CPA) has long been regarded as the time-reversed analogue of lasing, but its realization has been fundamentally constrained to steady-state interference under impedance-matching conditions. Here, we report the first experimental demonstration of transient CPA (TCPA), achieved by harnessing …

Far-field phonon coupling in valley metamaterial circuits

Yao Hsien Huang, Weitao Yuan, Zhiwei Guo, Qi Wang et autres

On-chip whispering-gallery-mode cavities enable versatile bosonic wave manipulation but typically rely on near-field evanescent coupling. Here we experimentally demonstrate broadband far-field phonon coupling in a valley metamaterial cavity integrated with a Dirac-cone waveguide-termed a "Dirac strip". The far-field coupling is confirmed by …

Efficient wireless power transfer enabled by anti-PT-symmetric nonlinear feedback

Yuqian Wang, Likai Wang, Shengyu Hu, Luyao Wan et autres

Efficiency and robustness are the fundamental challenges in resonance wireless power transfer (WPT). The application of non-Hermitian physics, particularly parity-time (PT) symmetry, in the field of WPT is currently under intense scrutiny from both theoretical and experimental perspectives. Typically, constructing an N …
