With a new lab-based experiment, researchers in the UK and France have recreated the characteristic cascades of energy and angular momentum that underpin key features of Earth's atmosphere. Reporting ...

a) In a weak magnetic field, broad cyclotron orbits suppress the orbital contribution, allowing spin polarization to dominate, (b) In strong magnetic fields, tight cyclotron orbits enhance orbital ...

Topological spin textures, spatially organized patterns linked to the intrinsic angular momentum of particles, have proved to be highly advantageous for the development of spintronics and quantum ...

Is it possible to drive nanoparticles to orbit below the light diffraction limit using a Gaussian beam? A recent joint research project reported in Nature Communications says yes. It is well known ...

In physics and materials science, the term "spin chirality" refers to an asymmetry in the arrangement of spins (i.e., the intrinsic angular momentum of particles) in magnetic materials. This asymmetry ...

An Aston University researcher has developed a new technique using light that could revolutionize non-invasive medical diagnostics and optical communication. The research showcases how a type of light ...

This course introduces the quantum mechanical concept of angular momentum operator and its relationship with rotation operator. It then presents the angular momentum operators, their eigenvalues and ...

Surprising as it may sound, 107 years after the introduction of general relativity, the meanings of basic concepts are still being worked out. More than a century after Albert Einstein unveiled ...
