Anharmonic lattice vibrations play pivotal roles in the thermal dynamics in condense matters
and affect how the atoms interact and conduct heat. An in-depth understanding of the …

In recent years, the spin Hall effect of light (SHE), also called the photonic spin Hall effect
has received extensive research attention, and a series of interesting results have been …

In ionic materials, circularly polarized phonons carry orbital magnetic moments that arise
from circular motions of the ions, and which interact with other magnetic moments or fields …

We analyze spin and orbital angular momenta in monochromatic acoustic wave fields in a
homogeneous medium. Despite being purely longitudinal (curl-free), inhomogeneous …

An acoustic vortex in an inviscid fluid and its radiation torque on an axisymmetric absorbing
object are analyzed beyond the paraxial approximation to clarify an analogy with an optical …

Unveiling spins of physical systems usually gives people a fundamental understanding of
the geometrical properties of waves from classical to quantum aspects. A great variety of …

Non-Abelian gauge fields give rise to nontrivial topological physics. Here we develop a
scheme to create an arbitrary SU (2) lattice gauge field for photons in the synthetic frequency …

We review the geometrical-optics evolution of an electromagnetic wave propagating along a
curved ray trajectory in a gradient-index dielectric medium. A Coriolis-type term appears in …

We present a solution to the problem of partial reflection and refraction of a polarized
paraxial Gaussian beam at the interface between two transparent media. The Fedorov …

Dualities are mathematical map**s that reveal links between apparently unrelated
systems in virtually every branch of physics,,,,,,–. Systems mapped onto themselves by a …
