Summary: In this study, we propose a transfer learning approach for modeling metal nanowires and predicting their waveguiding properties. With the guidance of physics, basic knowledge of plasmon modes is first learned from circular nanowires, which is then transferred to improve the performance of predicting waveguiding properties of nanowires with complex configurations. Our approach reduces errors, trainable parameters, and training data required compared to direct learning methods, and significantly reduces computational time. Compared to non-deep learning methods, our approach offers higher accuracies and more comprehensive characterizations, making it an effective and efficient framework for investigating metal nanowires.

Summary: Reliable single-photon sources, high coupling efficiency, and low propagation losses are key requirements for quantum plasmonic nanocircuits. The best overall performance of these nanocircuits is achieved by adding a spacer layer between the quantum dot and the plasmonic waveguide, resulting in an improved coupling efficiency through standing wave interference.

Summary: A tunable terahertz hybrid plasmonic waveguide based on a 3D Dirac semimetal elliptical fiber is investigated. Increasing the elliptical ratio leads to an increase in the real part of the effective mode index and propagation length. The figure of merit reaches more than 1500 and the propagation length shows a peak near the interface between the near field and dissipation regions.

Summary: This paper investigates the theoretical aspects of edge plasmon modes in a waveguide made of a double layer strip composed of graphene and black phosphorus (G-BP). The study focuses on the influence of the black phosphorus edge molecular configuration on the plasmonic mode properties. The anisotropy of black phosphorus significantly affects the modes, with armchair direction plasmons having lower losses and zigzag direction modes exhibiting stronger field confinement near the black phosphorus layer. By selecting appropriate parameters, the characteristics of the edge plasmon modes can be effectively controlled. The research also reveals that monolayer black phosphorus nanoribbons on low refractive index dielectric substrates are favorable for plasmonic applications due to low losses in the edge modes. These findings contribute to the advancement of integrated plasmonic devices based on the combination of graphene and black phosphorus.

Summary: This paper studies the one-dimensional structures of non-Hermitian plasmonic metallic nanospheres, revealing nontrivial physics emerging from strong non-radiative near field coupling between adjacent spheres. Investigation on a system of two identical spheres shows that when the width of uncoupled spheres' plasmonic resonance is twice the imaginary component of the coupling constant, the spheres become coupled through a single continuum channel, leading to distinguishable eigenmodes of superradiant states and dark states.

Summary: In this study, a theoretical model for infrared pulse propagation in graphene-covered hybrid waveguides is developed based on first principles. Electron dynamics in graphene and radiation propagation are described by Bloch equations and a generalized nonlinear Schrodinger equation, respectively. Numerical simulations show that Kerr solitons accelerate and experience a strong self-induced spectral blueshift, which is fully explained by semianalytical predictions.
