Abstract:

In the present article we report the dynamical behavior of entanglement between π-electrons and photons in Graphene. It is shown that the degree of such entanglements depend on the orientation of π-electron momenta relative to the photonic polarization. Moreover, we show that as the detuning between the π-electron transition frequencies and that of the photons is increased, the degree of entanglement decreases.

Linearly Polarized Photons

The process of electron-positron pair production by linearly polarized photons is used as a polarimeter to perform mobile measurement of linear photon polarization. In the limit of high photon energies, ω, the distributions of the recoil-electron momentum and azimuthal angle do not depend on the photon energy in the laboratory frame. We calculate the power corrections of order m/ω to the above ...

Photoproduction of Mesons with Linearly Polarized Photons

We propose to measure the reaction ~ + p! p+ with ! K+K in the photon energy range of 1:9 < E < 2:2 GeV by tagging the incident photon energy and detecting the nal-state proton in coincidence with the decayK+ in the CLAS detector. The photons will be produced by coherent bremsstrahlung from a 4 GeV (6 GeV) electron beam incident on a diamond radiator, and will provide an average polarization of...

Experimental Detection of Entanglement with Polarized Photons

We report on the first experimental realization of the entanglement witness for polarization entangled photons. It represents a recently discovered significant quantum information protocol which is based on few local measurements. The present demonstration has been applied to the so-called Werner states, a family of ”mixed” quantum states that include both entangled and non entangled states. Th...

Spin-polarized electrons in bilayer graphene ribbons

We show that a bilayer graphene ribbon deposited above a ferromagnetic insulator can behave as a spin-filtering device. The ferromagnetic material induces exchange splitting in the graphene ribbon, and due to the Fano antiresonances occurring in the transmission of the graphene ribbon as a function of ribbon length and energy, it is possible to obtain a net spin current. This happens when an an...

Emission of polarized photons from unpolarized electrons moving in crystals ∗

Radiation emitted by unpolarized high-energy electrons penetrating crystals may be linearly polarized. This occurs when the particle velocity makes an angle, with respect to some major crystal axis, being sufficiently larger than the axial-channelling angle. For such orientation, a complete description of spectral and polarization characteristics of the radiation is derived. At planar channelli...
