Quantization of scalar fields coupled to point-masses
J. Fernando Barbero, Benito A. Juárez-Aubry, Juan Margalef-Bentabol +1
We study the Fock quantization of a compound classical system consisting of point masses and a scalar field. We consider the Hamiltonian formulation of the model by using the geome…

Hamiltonian treatment of linear field theories in the presence of boundaries: a geometric approach
J. Fernando Barbero G., Jorge Prieto, Eduardo J. S. Villaseñor
The purpose of this paper is to study in detail the constraint structure of the Hamiltonian and symplectic-Lagrangian descriptions for the scalar and electromagnetic fields in the…
