Phase conjugation of twisted Gaussian Schell model beams in stimulated down-conversion

Nanophotonics, 2021
Stimulated parametric down-conversion is a nonlinear optical process that can be used for phase conjugation and frequency conversion of an optical field.

Relationship between Swimming Velocity and Trunk Twist Motion in Short-Distance Crawl Swimming

Biomechanics, 2023
This study aimed to estimate the trunk twist angle from the shoulder and hip rotation angles in short-distance crawl swimming and to elucidate the twist motion of the relationship between the trunk and the rotation angular velocity in response to changes

Geometric phase for twisted light

Optics Express, 2023
Polarization vectors of light traveling in a coiled optical fiber rotate around its propagating axis even in the absence of birefringence. This rotation was usually explained due to the Pancharatnam-Berry phase of spin-1 photons. Here, we use a purely geometric method to understand this rotation.

Experimental Synthesis and Demonstration of the Twisted Laguerre–Gaussian Schell-Mode Beam

Photonics, 2023
The twisted Laguerre–Gaussian Schell-model (TLGSM) beam is a novel type of partially coherent beam embedded with both the second-order twist phase and the classical vortex phase.

Evolution Properties of a Partially Coherent Twisted Laguerre-Gaussian Pulsed Beam Propagating through Anisotropic Atmospheric Turbulence

Photonics, 2022
Analytical expressions for the cross-spectral density matrix of a partially coherent twisted Laguerre-Gaussian pulsed (PCTLGP) beam in anisotropic atmospheric turbulence are derived based on the extended Huygens–Fresnel principle.

κ-Deformed Phase Space, Hopf Algebroid and Twisting [PDF]

Symmetry, Integrability and Geometry: Methods and Applications, 2014
Hopf algebroid structures on the Weyl algebra (phase space) are presented. We define the coproduct for the Weyl generators from Leibniz rule. The codomain of the coproduct is modified in order to obtain an algebra structure. We use the dual base to construct the target map and antipode.

Geometric Phase in Twisted Topological Complementary Pair

Advanced Science, 2023
AbstractGeometric phase enabled by spin‐orbit coupling has attracted enormous interest in optics over the past few decades. However, it is only applicable to circularly‐polarized light and encounters substantial challenges when applied to wave fields lacking the intrinsic spin degree of freedom. Here, a new paradigm is presented for achieving geometric
