Poincaré Rotator for Vortexed Photons
Frontiers in Physics, 2021 A Poincaré sphere is a powerful prescription to describe a polarized state of coherent photons, oscillating along certain directions. The polarized state is described by a vector in the sphere, and various passive optical components, such as polarization

Physical Review Research, 2021 In this paper we investigate the generation, manipulation and invariance properties of spatially unpolarized light in the context of classical optics. We generate spatially randomly polarized light by exploiting the optical activity of a so-called Cornu ...

SU(2) symmetry of coherent photons and application to Poincaré rotator
Frontiers in Physics, 2023 Lie algebra is a hidden mathematical structure behind various quantum systems realised in nature. Here, we consider SU(2) wavefunctions for polarisation states of coherent photons emitted from a laser source, and discuss the relationship to spin ...

Poincaré Beams at the Tight Focus: Inseparability, Radial Spin Hall Effect, and Reverse Energy Flow
Photonics, 2022 The family of Poincaré beams has three parameters, including two real-valued angular parameters, which specify a definite polarization state on the Poincaré sphere, and a third integer parameter n specifying the beam singularity order.

Poincaré Sphere and a Unified Picture of Wigner’s Little Groups
EPJ Web of Conferences, 2014 It is noted that the Poincaré sphere for polarization optics contains the symmetries of the Lorentz group. The sphere is thus capable of describing the internal space-time symmetries dictated by Wigner’s little groups.

Journal of Telecommunications and Information Technology, 2001 The aim of this work is to develop a coherent polarimetric model and to find a geometrical description of a monochromatic wave. The spinor form of the electrical field, its links to the coherency matrix and the Poincare` sphere are introduced with the ...

Polarimetric Quantum-Strong Correlations with Independent Photons on the Poincaré Sphere
Quantum Beam Science, 2022 Controllable, quantum-strong correlations of polarization states can be implemented with multi-photon independent states. Polarization-based photonic quantum correlations can be traced back to the overlap of the polarization Stokes vectors on the ...

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021 Abstract Background Posttraumatic stress disorder (PTSD) is associated with autonomic dysfunction as indicated by deficits in the sympathetic and parasympathetic nervous systems. These abnormalities are expressed as elevated heart rate and reduced heart rate variability (HRV), respectively.

Massive spinning bosons on the celestial sphere
Journal of High Energy Physics, 2020 A natural extension of the Pasterski-Shao-Strominger (PSS) prescription is described, enabling the map of Minkowski space amplitudes with massive spinning external legs to the celestial sphere to be performed. An integral representation for the conformal
