Summary: In this paper, a novel waveguide structure capable of supporting highly confined spoof surface plasmonic (SSP) mode with lower propagation loss is proposed. By analyzing the 2D and 3D structures of the waveguide, it is found that a subwavelength cross-sectional size waveguiding structure with high field confinement and low propagation loss can be achieved if the gap region is properly designed.

Summary: The upper limit of thermal conductivity mediated by long-range polaritons in asymmetric surrounding media was investigated. It was found that the thin film structure and asymmetric media can enhance the propagation of surface waves in free space, but fine tuning of the asymmetric permittivity is required to reach the maximum energy transmission efficiency.

Summary: This study develops the theory of optical effects in hydrogenated graphene (graphane) in the terahertz and infrared range. It analyzes the complex conductivity, reflection coefficient for graphane on a substrate, and dispersion of surface plasmon-polaritons. The calculations are based on a simple analytical approximation of graphane band structure near the Gamma-point and a modified model of quantum coherence relaxation. By comparing the theoretical results with experimental data, it is possible to determine graphane characteristics and investigate potential applications of this material in designing new optical elements.

Summary: A double-layer metal superlens was designed to improve subwavelength imaging ability. The transmission properties of the imaging system were accurately interpreted using waveguide mode theory. By amplifying high spatial frequency evanescent waves and diminishing low spatial frequency evanescent waves, a flat and broad optical transfer function was achieved, improving the subwavelength imaging performance.

Summary: This article investigates the dynamic modulation of optical skyrmions by changing the field symmetry and adding chirality. The study reveals that field symmetry controls the transformation between skyrmions and merons, while material chirality regulates the degree of twist in the fields and spins, and governs the skyrmionic transition. The enantioselective twist of skyrmions and merons arises from the chirality-induced splitting of the hyperboloid in momentum space. The research enriches the portfolio of optical quasiparticles and deepens our understanding of light-matter interaction, paving the way for applications such as chiral sensing, optical tweezing, and topological phase transitions in quantum matter.

Summary: This work reports the observation of 2D longitudinal aberrated wavefields by mapping the intensity distributions of surface plasmon polaritons (SPPs) propagating on a metal/air interface. The SPP beam orientation can be adjusted to mimic aberrated beams, showing Seidel terms such as defocus, spherical, coma, and tilt aberrations. This approach provides a visual and rapid examination of the longitudinal evolution of aberrated beams compared to more complicated post-processing reconstructions.

Summary: We investigate spontaneous entanglement of two qubits mediated by nonreciprocal surface plasmon polaritons (SPPs) in a Weyl semimetal. The nonreciprocal SPP gives better quantum entanglement than the reciprocal one, and the entanglement achieved in the Weyl semimetal is sufficiently long lived compared to the entanglement using SPPs in conventional metals.

Summary: This study demonstrates the challenges of modulating near-field radiative heat transfer (NFRHT) with a high dynamic range in nanoscale thermal science and engineering. The researchers achieved a modulation depth of approximately 32.2% using a pair of graphene-covered SU8 heterostructures. The results show the importance of symmetry in polariton-mediated NFRHT and represent the largest modulation depth to date in a two-body system with fixed gap distance and temperature.
