Hailed as a pioneer by Photonics Media for his previous discoveries of supercontinuum and Cr tunable lasers, City College of New York Distinguished Professor of Science and Engineering Robert R. Alfano and his research team are claiming another breakthrough with a new super class of photons dubbed "Majorana photons." They could lead to enhanced information on quantum-level transition and imaging of the brain and its working.
Alfano's group based its research on the fact that photons, while possessing salient properties of polarization, wavelength, coherence and spatial modes, take on several forms. "Photons are amazing and are all not the same," Alfano states.
Their focus "was to use a 'special super form' of photons, which process the entanglement twists of both polarizations and the wavefront to probe and would propagate deeper in brain tissues, microtubules and neuron cells, giving more fundamental information of the brain than the conventional photon forms."
These unique photons can travel with different wavefronts. They also have a vortex where the wavefront twists and polarization is non- homogenous in the wave beam diameter. These beams are called Cylindrical Vector Vortex Beams (CVVB).
Among these CVVB photons, the Alfano team identified a new "super special" class called classical entangled photon beams. These photons are mixed having both different types of circular polarization and + L and - L orbital angular momentum, locally. In addition, they are entangled with their own anti photon. Two stand out Radial and Azmuthal optical beams.
Alfano named them "Majorana Photons," after Ettore Majorana, an Italian theoretical physicist and protégé of Enrico Fermi, who worked on neutrino masses.
"The 'super special photon" will play an important role in understanding the fundamental and quantum processes in materials, deeper penetration and to advance applications in photo detection sensing, information, communication and future computers," said Alfano, a prolific inventor whose research has led to advancements in ultrafast laser science and nonlinear optical imaging, since 1970.
This research was partly funded by a five-year $1.5 million grant from the United States Army Research Office (ARO) to investigate quantum effects in brain, microtubules, and neuron cells.
Alfano's collaborators in ARO grant included Travis Craddock (Nova Southeastern University); Lingyan Shi (University of California San Diego) and Enrique Galvez (Colgate University), Daniel Nolan (Corning), and Sandra Mamani, an electrical engineering PhD student at CCNY.

Soft robots have a distinct advantage over their rigid forebears: they can adapt to complex environments, handle fragile objects and interact safely with humans. Made from silicone, rubber or other stretchable polymers, they are ideal for use in rehabilitation exoskeletons and robotic clothing. Soft bio-inspired robots could one day be deployed to explore remote or dangerous environments.
Most soft robots are actuated by rigid, noisy pumps that push fluids into the machines' moving parts. Because they are connected to these bulky pumps by tubes,...
Researchers at TU Graz are working together with European partners on new possibilities of measuring vehicle emissions.
Today, air pollution is one of the biggest challenges facing European cities. As part of the Horizon 2020 research project CARES (City Air Remote Emission...
Over the next three years, researchers from the Vrije Universiteit Brussel, University of Cambridge, École Supérieure de Physique et de Chimie Industrielles de la ville de Paris (ESPCI-Paris) and Empa will be working together with the Dutch Polymer manufacturer SupraPolix on the next generation of robots: (soft) robots that ‘feel pain’ and heal themselves. The partners can count on 3 million Euro in support from the European Commission.
Soon robots will not only be found in factories and laboratories, but will be assisting us in our immediate environment. They will help us in the household, to...
Scientists at the University of Leeds have created a new form of gold which is just two atoms thick - the thinnest unsupported gold ever created.
The researchers measured the thickness of the gold to be 0.47 nanometres - that is one million times thinner than a human finger nail. The material is regarded...
An international team of scientists involving the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg has unraveled the light-induced electron-localization dynamics in transition metals at the attosecond timescale. The team investigated for the first time the many-body electron dynamics in transition metals before thermalization sets in. Their work has now appeared in Nature Physics.
The researchers from ETH Zurich (Switzerland), the MPSD (Germany), the Center for Computational Sciences of University of Tsukuba (Japan) and the Center for...
