ELECTRODINÁMICA QUIRAL: ESLABÓN PARA LA UNIFICACIÓN DEL ELECTROMAGNETISMO Y LA GRAVITACIÓN/ CHIRAL ELECTRODYNAMIC: CONNECTION FOR THE UNIFICATION OF ELECTROMAGNETISM AND GRAVITATION

Torres-Silva, Héctor

Resumen en español Una alternativa a la teoría cuántica de la gravedad, aún no descubierta, es la Teoría Total Simplificada (TTS) aquí propuesta, que postula unificar la gravedad con el electromagnetismo (EM) teniendo como corolario fundamental la ecuación cuántica de Dirac. Con ello, aquí se propone todo un programa de unificación en el cual el electromagnetismo quiral juega el rol central. La TTS se deriva de las ecuaciones originales de Einstein-Hilbert (mas) ight=21 src="http:/fbpe/img/ingeniare/v16nespecial/image002.gif">, donde el tensor de Einstein no se modifica. El tensor EM en cambio es quiral y la masa de las partículas es de naturaleza electromagnética. Para el caso del electrón se tiene como consecuencia que, por primera vez, se obtiene la ecuación de Dirac a partir de ondas EM con el campo eléctrico paralelo espacialmente al campo magnético. Como modelo del universo se propone una interfaz o membrana de separación donde ocurren solamente eventos cuánticos. Hay dos regiones enantioméricas de un universo cerrado, o un universo derecho y un universo izquierdo, relacionados por un elemento de simetría PCT (paridad, carga, tiempo) a lo largo de la interfaz. Las ecuaciones de Einstein-Hilbert son estudiadas bajo el enfoque quiral y se discute la electrodinámica quiral y la gravedad en la era de Planck Resumen en inglés An alternative to the theory of quantum gravity, not yet discovered, is the Theory Simplified Total (TTS) proposal, which aims to unify gravity with the EM taking as a corollary the essential quantum Dirac equation. Thus, this article proposes a whole program of unification in which chiral electromagnetism plays the main role. TTS is derived from the original equations of Einstein-Hilbert (mas) .gif">, where the Einstein tensor is unchanged. The EM tensor instead is chiral and the mass of the particles has an electromagnetic nature. In the case of the electron the consequence of this is that, for the first time, Dirac's equation is obtained from EM waves with the electric field spatially parallel to the magnetic field. As a model of the universe an interface or membrane separation is proposed as the only location for quantum events. There are two enanciometrics regions in a closed universe, or right and left universe, connected by an element of PCT (parity, charge, time) symmetry along the interface. Einstein-Hilbert equations are studied under the chiral approach and the chiral electrodynamics and gravity in Planck's era are discussed

The electronic spectrum of fullerenes from the Dirac equation

González Fernández, Jesús María; Guinea, Francisco; Hernández Vozmediano, M. Angeles

The electronic spectrum of sheets of graphite (plane honeycomb lattice) folded into regular polyhedra is studied. A continuum limit valid for sufficiently large molecules and based on the tight-binding approximation is derived. It is found that a Dirac equation describes the flat graphite lattice. C...

Gluino zero-modes for calorons at finite temperature

García Pérez, Margarita; González-Arroyo, Antonio; Sastre, Alfonso

16 pages, 2 figures, LateX. | We study the solutions of the Dirac equation in the adjoint representation(gluinos) in the background field of SU(2) unit charge calorons. Our solutions are forced to be antiperiodic in thermal time and would occur naturally in a semiclassical approach to N=1 Super-symm...
