The photonic spin Hall effect (SHE) arises from the spin–orbit interaction of lights and plays
an important role in light–matter interactions. The phenomenon of spin‐momentum locking …

Spin-momentum locking is a universal wave phenomenon promising for applications in
electronics and photonics. In acoustics, Lord Rayleigh showed that surface acoustic waves …

Skyrmions are topologically protected quasi-particles that have aroused substantial interest
in nuclear physics and condensed matter physics. For instance, magnetic skyrmions are …

We investigate the spin-orbit coupling of light in three-dimensional cylindrical and tubelike
whispering gallery mode resonators. We show that its origin is the transverse confinement of …

We study the interplay of electron and photon spin in nonreciprocal materials. Traditionally,
the primary mechanism to design nonreciprocal photonic devices has been magnetic fields …

The interplay of photon spin and orbital angular momentum (OAM) in the optical fiber (one-
dimensional waveguide) has recently risen to the forefront of quantum nanophotonics. Here …

Control and manipulation of the angular momentum of optical, electronic, or light-matter
interacting systems has given rise to a myriad of applications. Majority of these applications …

We study the radiation of a circular dipole nearby a subwavelength spherical particle. The
circular dipole spins in a plane containing a great circle of the spherical particle (meridional …
