We present an overview of the main issues concerning the orbital angular momentum of
light, starting form the framework of its definition, passing through the developments of the …

We theoretically verify that a coherent superposition of nearly degenerate Bessel beams
characterizes the family of resonant geometric modes in circular billiards. With the ray-wave …

We use differential Ramsey interferometry of ultracold atoms to characterize the vector light
shift (VLS) from a far-off-resonance optical dipole trap at λ= 1064 nm. The VLS manifests as …

We show that double-charged optical vortices can be generated with the help of Kerr electro-
optic effect in either single crystals or isotropic media, including gaseous and liquid ones …

In this paper, we have studied the propagation of light in ap array, that is, a circular array of
strongly anisotropic fibers, orientation of whose anisotropy axes linearly depends on the …

Silver ion-exchanged glass exhibits nonlinear optical properties upon interacting with
intense light beams. The thermal effect due to the nanoparticles' light-absorption induces …
