Relativistic two-component geometric approximation of the electron-positron contribution to magnetic properties in terms of Breit-Pauli spinors
(American Institute of Physics, 2009-12)
An alternative approach for the calculation of the electron-positron (e-p) contribution to magnetic properties based on two-component Breit-Pauli spinors is presented. In it, the elimination of the small component scheme ...
A criterion for the existence of zero modes for the Pauli operator with fastly decaying fields
(AMER INST PHYSICS, 2015)
We consider the Pauli operator in R-3 for magnetic fields in L-3/2 that decay at infinity as vertical bar x vertical bar(-2-beta) with beta > 0. In this case, we are able to prove that the existence of a zero mode for this ...
Hamiltonian positivity of massive spin-2 particles via a rank-2 tensor
(2017-01-31)
There are three families of Lagrangians describing massive spin-2 particles via a general (nonsymmetric) rank-2 tensor. Each of those families depends on an arbitrary real parameter, one of them includes the paradigmatic ...
Estructura de la función de onda multifermiónica en sistemas simples y su relación con las restricciones de Pauli generalizadas
(Maestría en Ciencias - FísicaFacultad de CienciasDepartamento de Física, 2016)
Una forma adecuada para describir sistemas cuánticos de muchos cuerpos es a través de los operadores densidad reducidos de uno y dos cuerpos, ya que las interacciones consideradas en física se describen por operadores de ...
