Light is a natural phenomenon. It is a photon stream in a specific frequency band and has wave-particle duality, being both an electromagnetic wave and a stream of photons. 光是一种自然现象,是处于特定频段的光子流,具有波粒二象性,既是一种电磁波,也是...
The precise control over light promotes mankind to stride towards the age of information technology. Birefringence-tunable hydrogel based on 2D materials can act as a new type of optical element, which enables fabrication of the first deep ultraviolet mod...

Motivated by Lord Kelvin’s knotted vortex atom hypothesis1, Tony Skyrme2 in 1961 proposed a topological model for nuclei: particle-like continuous fields in 3D space now called skyrmions. These map 3D real space to the hypersphere (i.e. the unit sphere in four dimensions, also known as ...
5c), taking advantage of their capabilities such as high efficiency. New forms of light It is also highly topical to explore higher-dimensional structured light by referring models from different disciplines, e.g., topology, particle physics, and condensed matter. Here we would like to point ...

A light string is attached to the vertex of a smooth vertical cone. A particle P of mass m is attached to the string as shown in the diagram. The particle remains in contact with the cone and rotates with constant angular velocity ω on a circle of radius r. The string and the ...
One of the best things about using a light particle Photoshop brush is that it has such a wide range of uses, such as adding a bokeh effect, a sparkle effect, dust particles, and even snow effects! To get started with this tutorial, we'll need a photograph or image to use as a ...
Light scattering by small particles has a long and interesting history in physics. Nonetheless, it continues to surprise with new insights and applications. This includes new discoveries, such as novel plasmonic effects, as well as exciting theoretical and experimental developments such as optical trapp...
