Summary: This article studies the inertial motion of smooth and frictionless objects on the rotating Earth in a rotating frame of reference. A new class of motion called "circumpolar waves" is identified and illustrated using CorioVis, a freely available Coriolis visualization software. The article also provides calculations for experimentally relevant frequencies, zonal drifts, and latitude ranges.

Summary: Optical tweezers are essential tools in physics, chemistry, and biology for precise micromanipulation and force measurement. This study presents a general approach based on sampled trajectories to accurately estimate the trap stiffness and diffusion constant of optically trapped particles by correcting for the biases caused by finite integration time and limited sampling frequency.

Summary: The working mechanism of single-beam optical tweezers is thoroughly examined using a newly established method. The conservative and nonconservative components of optical force are calculated for different optical regimes, and the concept of an "optical trapping core" is proposed to better illustrate the stability of the trapping process.

Summary: This paper theoretically studies the modulation of local optical force on a dielectric sphere by optimizing the phase profile of the incident light. By using a genetic algorithm, the optimization of the phase profile can enhance the optical force significantly. The results show that smaller spheres can benefit more from optical force modulation, with the phase profile amplifying the strength of the optical force.

Summary: This paper investigates the propagation properties of the odd-Pearcey Gaussian beam (OPGB) in a parabolic potential. It is found that, in addition to auto-focusing at the focal plane, the OPGB unexpectedly performs weak off-axis focusing. By choosing an appropriate parabolic parameter, the focusing distance and focal intensity can be adjusted.

Summary: The relationship between the Rayleigh limit of the generalized Lorenz-Mie theory (GLMT) and the dipole theory of forces is investigated, revealing extreme accuracy between the two approaches up to 3000 decimal places, reinforcing the conjecture that the Rayleigh limit of the GLMT might exactly identify with the traditional dipole theory of forces. However, mathematically uncovering such identification remains to be done.

Summary: This study extends the previous research on optical forces exerted on Rayleigh particles to the case of small magnetodielectric particles. It introduces a partition between gradient, scattering, and non-standard forces and emphasizes the relationship between these non-standard forces and curl forces in the framework of a dipole theory.

Summary: This study introduces a mechanism to propel particles towards one central space by creating a converging wave field without significant reflections. The method is based on a theoretical prediction model of acoustic pressure fields and is validated using numerical simulations and experimental data, demonstrating effective clustering of micro-particles.

Summary: In this study, the categorization of optical forces in generalized Lorenz-Mie theory is systematically examined. The focus is on the forces exerted on quadrupoles and their explicit expressions in terms of beam shape coefficients and Mie coefficients. The categorization is done at three levels, distinguishing between mixing forces and recoil forces, and between gradient and non-gradient forces. A third level is proposed to further decompose the so-called scattering forces into scattering forces and non-standard forces.

Summary: Two recent papers demonstrate the existence of new optical forces and terms when a Rayleigh particle is illuminated by an off-axis Bessel beam, mainly associated with the axicon angle. These forces and terms are found in both longitudinal and transverse forces studies, showing additional axicon forces linked to the usual scattering and gradient forces. These extra-axicon forces are zero when the axicon angle is zero or in an on-axis configuration rather than off-axis.

Summary: During the last decade, new unusual physical phenomena have been discovered in studying the optics of dielectric mesoscale particles with a Mie size parameter near 10 (q~10). This paper provides an overview of these phenomena in optics, terahertz, plasmonic, and acoustic ranges. The discussion on different particle configurations and potential applications indicates a promising scientific direction in optics, terahertz, acoustic ranges, and plasmonics.

Summary: A near-field optical trapping scheme using plasmonic C-shaped nano-engraving is proposed, which achieves dynamic controllability of the electric field and trapping force. The implementation of the plasmonic tweezers allows for lower-field trapping and reduces the chance of thermal damage to sensitive specimens.

Summary: This study complements previous work on optical forces and force categorizations on dipole particles with electric and magnetic properties in the generalized Lorenz-Mie theory. It establishes a rigorous connection between the dipole limit of the GLMT and the dipole theory of forces (DTF) for such particles.

Summary: This paper is the final one in the series of papers aiming to partition optical forces within the framework of generalized Lorenz-Mie theory. It focuses on forces exerted on particles of arbitrary size, expressing them in terms of beam shape coefficients and Mie coefficients. The partition is based on a three-level categorization and a two-level decomposition, allowing for a comprehensive understanding of the forces involved. (c) 2023 Elsevier Ltd. All rights reserved.

Summary: The uncertainty principle limits our ability to predict the outcomes of two incompatible measurements, with the Robertson-Schrödinger uncertainty relation considering the covariance between two observables. Quantum states such as qubits satisfy the equality of this uncertainty relation, and visualizing the quantities involved in these relations on the Bloch sphere can help distinguish specific properties and symmetries.

Summary: The paper presents the precise equations needed to design a stigmatic singlet lens that meets Herschel's condition. The first and second refractive surfaces of the lens are determined analytically for this purpose, and a nonlinear differential equation is numerically solved. Illustrative examples of the new family lenses are shown, along with a discussion of their limitations.

Summary: The paper presents general solutions to the Schrodinger equation for a di-periodic potential, extending it from the standard sinusoidal potential. Two different approaches were used to solve the three-term Whittaker-Hill equation with the di-periodic potential, resulting in the determination of Floquet-Bloch eigenwaves and band structure. Additionally, it was found that the Ince functions can describe the Mathieu functions obtained with purely sinusoidal potentials.

Summary: The method introduced in this study allows analytically determining the shape of a lens's refractive surfaces for coupling two arbitrary given wavefronts, without assuming paraxiality or numerical approximations. Applicability restrictions were discussed, and tests showed consistent and expected results for various wavefronts and conditions. The system can be considered bi-directional as the user arbitrarily defines both wavefronts.
