Summary: This study investigates the Goos-Hanchen shift of silicene in different phases and finds a large negative spatial GH shift in metal phases and a positive shift in nonmetallic states. The angular GH shift varies rapidly near the pseudo-Brewster angle, allowing manipulation of the GH effect by controlling external circularly polarized light electric field or magnetic field. These results are believed to be helpful for developing novel optoelectronic devices based on the GH effect of silicene.

Summary: This paper proposes a new metasurface to achieve reflection-type bound states in the continuum (BIC), which can significantly enhance the Goos-Hanchen (GH) shift. The maximum GH shift can reach more than 400 times the resonant wavelength, and is located exactly at the reflection peak with unity reflectance, allowing for detection of the GH shift signal. Furthermore, the metasurface can be used to detect variations in the refractive index, with a sensitivity of 3.58 x 10(6) μm/RIU according to simulation calculations.

Summary: The study investigates the Goos-Hanchen angular shift in a metal subwavelength grating excited by surface plasmon resonance. The research demonstrates extremely large angular shifts for an optimal depth of the subwavelength grating. Rigorous electromagnetic simulation and experimental evidence showcase the high sensitivity of beam shape transformation and the Goos-Hanchen shift to changes in the angle of incidence near the surface plasmon resonance. Additionally, the study showcases the focusing of reflected beams near the subwavelength grating surface.

Summary: In this letter, the large transmitted optical positive and negative Goos-Hanchen shifts in photonic crystal slabs are demonstrated both numerically and experimentally. The observed Goos-Hanchen shift reaches up to 20 μm, 30 times the wavelength, which is close to the beam waist radius. By measuring the transmission phase, an acute phase change near the resonance in photonic crystal slabs is discovered, which enhances the Goos-Hanchen shift. The experimental results are consistent with simulations, and this work can be utilized for further research on light propagation modulation.

Summary: This theoretical study investigates the temperature-dependent Goos-Hanchen shifts in a symmetrical graphene-cladding waveguide. It is found that the temperature mainly affects the thickness of the guiding layer and tiny temperature fluctuations can result in significant deviations in GH shifts. By adjusting the Fermi energy, these deviations can be efficiently improved, potentially leading to a high-sensitivity temperature sensing scheme with applications in optical temperature sensors.

Summary: In this study, beam models of Goos-Hanchen (GH) and Imbert-Fedorov (IF) effects in tilted Weyl semimetals (WSMs) are established, and the influences of Weyl cone tilting and chemical potential on the GH and IF shifts are systematically studied. It is found that the GH and IF shifts in tilted type-I and type-II WSMs are both almost symmetric about the Weyl cone tilting, but the dependence on the tilt degree differs in different types of WSMs.

Summary: In this manuscript, the Goos-Hanchen shift of the transmitted and reflected probe beam is controlled and modified by introducing the position and orbital angular momentum dependency in the Rabi frequencies of the control fields. The system parameters and azimuthal quantum number are used to control and modify the G-H shift as well as the topological regions. Crater and peak type topological regions are reported in the G-H shift of the reflected and transmitted beam. The modified results might have significant applications in optical waveguide switches and sensors.

Summary: This paper theoretically studies a bimetallic sensor based on graphene-hexagonal boron nitride (hBN) heterostructure, aiming to improve sensitivity in the infrared band by enhancing the Goos-Hanchen shift. By adjusting the Fermi level, number of graphene layers, and thickness of hBN, a GH shift of 182.09 lambda can be achieved. With specific parameters, a sensitivity of 2.02 x 10(5) lambda/RIU can be reached, indicating high sensitivity and stability of the infrared sensor. This research provides a theoretical basis for the design of a new high-sensitivity infrared band sensor.

Summary: Based on full wave simulation and the Maxwell stress tensor theory, this study demonstrates an enhanced transverse optical gradient force acting on Rayleigh particles immersed in a simple optical field formed by two linearly polarized plane waves. The force can be enhanced by two orders of magnitude via coating an extremely thin silver shell on the conventional dielectric particle. The enhanced force mainly comes from the interaction between the incident field and the electric quadrupole excited in the core-shell particle. In addition, the optical potential energy and the optical trapping stiffness for the core-shell particle are greatly enhanced, making stable optical trapping possible.

Summary: Based on the multipole expansion theory, it is shown that a transverse optical torque acting on a dipolar plasmonic spherical nanoparticle can be anomalously enhanced in two plane waves with linear polarization. Compared to a homogeneous Au nanoparticle, the transverse optical torque acting on an Au-Ag core-shell nanoparticle with an ultra-thin shell thickness can be dramatically enhanced by more than two orders of magnitude. This enhanced transverse optical torque is dominated by the interaction between the incident optical field and the electric quadrupole excited in the dipolar core-shell nanoparticle. It is noted that the torque expression based on the dipole approximation usually used for dipolar particles is not available even in our dipolar case. These findings deepen the understanding of the optical torque and may have applications in optically driven rotation of plasmonic microparticles.

Summary: An arbitrary conical angle is introduced to study the propagation properties of circular Airy beams beyond the paraxial approximation. It is found that the nonparaxiality becomes obvious for large conical angles, and the field intensity at the focal point can be enhanced by adjusting the conical angle. Moreover, the longitudinal component of the field is enhanced and the longitudinal gradient of the field intensity is enlarged for large conical angles, suggesting the possibility of stable optical trapping for microparticles.

Summary: This study demonstrates that under specific conditions, spherical particles can experience lateral optical forces in optical fields formed by multiple circularly polarized plane waves, with the force magnitude depending on the Poynting vector of the illuminating field. The spatial distribution of the lateral optical force is primarily determined by the illuminating field's Poynting vector, while the particle material and size mainly affect the force magnitude rather than the spatial profile. These findings enrich the concept of lateral optical forces and provide a new approach for optical manipulation.
