Electron beams have transcended their traditional roles in imaging and lithography to become vital platforms for exploring fundamental quantum phenomena. Central to recent advances is the manipulation ...

This paper is concerned chiefly with the introduction of a co-ordinate operator in the quantum mechanics of the electron. It differs from other work on the same subject in the derivation of the form ...

Hybrid continuous-variable (CV) and discrete-variable (DV) entanglement is an essential quantum resource of hybrid quantum information processing, which enables one to overcome the intrinsic ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.230184 , discusses tailoring electron vortex beams with customizable intensity patterns by electron diffraction holography. In ...

Photons with a twisted phase front carry a quantized amount of orbital angular momentum (OAM) and have become important in various fields of optics, such as quantum and classical information science ...

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 ...

When a magnetic material is bombarded with short pulses of laser light, it loses its magnetism within femtoseconds (10 –15 seconds). The spin, or angular momentum, of the electrons in the material ...

Chiral phonons are vibrations where atoms move in a circular pattern when energized, for example, by heat. As these ...

In the early 1920s, physicists were first working out the mysteries of the quantum Universe. Particles sometimes behaved as waves, with indeterminate positions, momenta, energies, and other properties ...

A new study published in Nature Physics introduces a theory of electron-phonon coupling that is affected by the quantum geometry of the electronic wavefunctions. The movement of electrons in a lattice ...

A century ago, the German physicists Otto Stern and Walther Gerlach carried out an experiment that gave an important credibility boost to the new-fangled notion of quantum mechanics. But as Hamish ...
