“…As explained in our previous article , when a photon (ω) enters a material it becomes dressed by the refractive index n(ω). A photon can excite electrons causing vibrations, which couple to the media quasi‐particles generating plasmons, optical photons, magnons, excitons and/or polaritons depending on how ω gets close to the resonance frequency ω o .…”

This paper extends the concept of entangled vector vortex beams as a form of Majorana‐like photons. Majorana photon quasi particles are introduced and attributed to a class of entangled vector beams and show higher transmission. These photons and the antiphotons are identical. A Majorana photon has within itself both right and left handed twists. These majorana beams travel at speeds other than speed of light, c in free space. Light transmission of Majorana photon vortex beams with orbital angular momentum (OAM) are investigated in a mouse brain at different local regions showing enhanced transmission and properties of being entangled. This work is new interpretation of our past paper of mixed photon beam states. The transmission change observed with Majorana structured light other than linear polarization is attributed to the nonseparable and mixed nature of radial and azimuthal polarizations with OAM and the handedness of the light passing through chiral brain media. These mixed nonhomogeneous beams are entangled in OAM and polarization. Majorana photons may play an important role in the future for quantum and optical computing and sub and super luminal speeds due to its traversal wave vector, k.

“…The interest in Orbital Angular Momentum (OAM) states of light, or twisted light, has been continuously growing since the publication by Allen et al in 1992 [1]. Within the last two decades considerable progress has been made towards understanding the mechanism of photon OAM transfer to the external and internal degrees of freedom in various systems, including turbid media [2,3], bulk semiconductors [4], and solid state heterostructures [5]. For recent reviews see, e.g.…”

Inter-band photo-excitation of electron states with the twisted photons in GaAs, a direct band-gap bulk semiconductor, is considered theoretically. Assuming linearity of the quantum transition amplitudes and applying Wigner-Eckart theorem, we derive a plane-wave expansion of twisted-photon amplitudes. We also obtain relative probabilities for magnetic sub-level population of the photoelectrons in conduction band. The approach for calculating the position dependent electron polarization, resulting from photo-absorption of twisted light, is described for vertical transitions in the Γpoint. Theoretical predictions for GaAs show modification of the magnitude and the sign of photoelectron polarization in the region near photon's phase singularity.arXiv:1809.05169v2 [cond-mat.mes-hall]

“…There are also reports of 'magneto-orbital' dichroism, an OAM analogue of magnetic circular dichroism 32 , and the use of stimulated parametric down conversion to produce a dichroic-like effect through direct action of the OAM in an incident field 33 . Studies looking at Mie scattering 34,35 also suggest that the sign of in the incident beam is important in these processes, and it has recently emerged that there exists an optical OAM-sensitive transmission rate of LG beams through mouse brain tissue 36 .…”

The unique role that can electric quadrupole transition moments play in chiroptical interactions has recently been established with twisted light beams. Manifesting a spin-orbit interaction in paraxial light, the engagement of electric quadrupoles in electronic transitions is highlighted in optical phenomena such as absorption, in both chiral and achiral media. However, spin-orbit interactions of light are also well-known in scattering from small particles, and recent exploratory experimental work suggests a chiroptical interaction of this nature in the scattering of optical vortex beams. Using a quantum electrodynamical formulation, such a sensitivity to the handedness of a vortex beam is accounted for in molecular scattering processes.  etc. Interestingly, the spatial distribution of the scattering associated with this mechanism therefore exhibits the intrinsic symmetry of a quadrupole.
