In the past decade, optical orbital angular momentum (OAM) has entered the field of
plasmonics in the form of surface-confined vortices, generating vast interest. Here we give …

Light contains both spin and orbital angular momentum. Despite contributing equally to the
total photonic angular momentum, these components derive from quite different parts of the …

Twisted light carries a nonzero orbital angular momentum, that can be transferred from light
to electrons and particles ranging from nanometers to micrometers. Up to now, the interplay …

Light-matter interaction is a long-standing promising topic that can be dated back to a few
centuries ago and has witnessed the long-term debate between the particle and wave …

Investigation of light–matter interactions in two-dimensional (2D) semiconductors is
essential to understand many-body effects and explore their applications in photonics. 2D …

Recent studies have revealed that chiral phonons resonantly excited by ultrafast laser
pulses carry magnetic moments and can enhance the magnetization of materials. In this …

We study the orbital angular momentum of magnons for collinear ferromagnet (FM) and
antiferromagnetic (AF) systems with nontrivial networks of exchange interactions. The orbital …

Spin angular momentum of a photon corresponds to a polarisation degree of freedom of
lights, and such that various polarisation properties are coming from macroscopic …

Orbital Angular Momentum (OAM) of photons are ubiquitously used for numerous
applications. However, there is a fundamental question whether photonic OAM operators …

A fundamental requirement for quantum technologies is the ability to coherently control the
interaction between electrons and photons. However, in many scenarios involving the …
