Dynamics of Entanglement between Linearly Polarized Photons and π -Electrons in Graphene

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 entang...

A Model of Composite Electrons and Photons

It is shown that electrons and photons can be considered as composities of particles belonging to the fundamental representations of the extended Lorentz group SU(3) ⊗ SU(3) in (8+1) dimensional space-time which are held together by force mediated by gauge particles belonging to the regular representation of this group. In this theory, spin states of electron, positron and photon form a 8⊗8 rep...

Energy spectra of two electrons in a circular quantum dot

The energy spectrum of two interacting electrons in a flat circular quantum dot is investigated. While the centre of motion can be treated exactly, the Wentzel-Kramers-Brillouin (WKB) approximation has been applied to study the relative motion. The energies are seen to agree well with the exact numerical results.

Electrons and Photons: Fact not Fiction

The particle Fock space of the matter fields in QED can be constructed using the free creation and annihilation operators. However, these particle operators are not, even at asymptotically large times, the modes of the matter fields that enter the QED Lagrangian. In this letter we construct the fields which do recover such particle modes at large times. We are thus able to demonstrate for the f...
