Bose-Einstein condensation of tunnelling photons in the brain cortex as a mechanism of conscious action
Quantum brain dynamics (QBD) consciousness
2015/7/30
Mind is supposed to be a macroscopic quantum wave governing the dynamics of the quantum coherent cytoskeletal protein system inside the cytoplasm of the brain cortical neurons. Its dynamical timescale...
Tevatron Searches for New Physics with Photons and Jets
Fermilab's tevatron the standard model of physics
2014/12/18
The D and CDF experiments have each collected more than 8 fb..1 in Run II of Fermilab's Tevatron, and have many recent search results which use up to 5.2 fb..1. Here I summarize the results of a vari...
The total radiant energy, and the average depth of all the photons, in the water column
The total radiant energy the average depth all the photons in the water column
2014/4/2
Using radiative transfer theory I show that for a given waveband, the total radiant energy,Qt, present within the water column (per square meter of surface) is proportional to the scalar irradiance ju...

Manipulating infrared photons plasmons transparent graphene superlattices
2012/2/27
Superlattices are artificial periodic nanostructures which can control the flow of electrons. Their operation typically relies on the periodic modulation of the electric potential in the direction of ...
Angular distribution of Bremsstrahlung photons and of positrons for calculations of terrestrial gamma-ray flashes and positron beams
Bremsstrahlung pair production analytical integration of Bethe-Heitler equation distribution of scattering angles
2012/2/28
Within thunderstorms electrons can gain energies of up to hundred(s) of MeV. These electrons can create X-rays and gamma-rays as Bremsstrahlung when they collide with air molecules. Here we calculate ...
Constraints on the origin of ultra-high-energy cosmic rays from cosmogenic neutrinos and photons
Astroparticle physics Acceleration of particles Abundances Neutrinos Gamma-rays Relativistic processes
2011/10/11
We study the production of cosmogenic neutrinos and photons during the extragalactic propagation of ultra-high-energy cosmic rays (UHECRs). For a wide range of models in cosmological evolution of sour...
Theory of quantum frequency translation of light in optical fiber: application to interference of two photons of different color
quantum frequency translation light optical fiber photons Quantum Physics
2011/8/17
Abstract: We study quantum frequency translation and two-color photon interference enabled by the Bragg scattering four-wave mixing process in optical fiber. Using realistic model parameters, we compu...
Coherent manipulation of spin wave vector for polarization of photons in an atomic ensemble
spin wave vector Coherent manipulation polarization of photons atomic ensemble
2011/8/3
Abstract: We experimentally demonstrate the manipulation of two-orthogonal components of a spin wave in an atomic ensemble. Based on Raman two-photon transition and Larmor spin precession induced by m...
Inter-electronic interaction effects on the polarization of recombination photons
Inter–electronic recombination photons
2011/9/6
A theoretical investigation of the radiative capture of an electron into a bound state of heavy,hydrogen–like ion is presented. Special attention is paid to the question of how the linear polarization...
99% efficiency in collecting photons from a single emitter
collecting photons a single emitter
2011/9/14
In Nature Photonics 5, 166 (2011), we reported on a planar dielectric antenna that achieved 96% efficiency in collecting the photons emitted by a single molecule. In that work the transition dipole mo...
Electromagnetism with Magnetic Charge and Two Photons
Electromagnetism Magnetic Charge classical electromagnetism High Energy Physics - Theory
2011/7/27
Abstract: The Dirac approach to include magnetic charge in Maxwell's equations places the magnetic charge at the end of a string on which the the fields of the theory develop a singularity. In this pa...
Simulating quantum statistics with entangled photons: a continuous transition from bosons to fermions
quantum statistics entangled photons bosons fermions
2011/9/9
In contrast to classical physics, quantum mechanics divides particles into two classes|bosons and fermions|whose exchange statistics dictate the dynamics of systems at a fundamental level . In two dim...
