Hamiltonian analysis and positivity of a new massive spin-2 model
(2022-02-03)
Recently a new model has been proposed to describe free massive spin-2 particles in D dimensions in terms of a non symmetric rank-2 tensor e μν and a mixed symmetry tensor B μ[αβ]. The model is invariant under linearized ...
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 ...
Configuration interaction wave functions: A seniority number approach
(American Institute of Physics, 2014-06)
This work deals with the configuration interaction method when an N-electron Hamiltonian is projected on Slater determinants which are classified according to their seniority number values. We study the spin features of ...
The Schwinger model on the null-plane
(2007-10-01)
We study the Schwinger Model on the null-plane using the Dirac method for constrained systems. The fermion field is analyzed using the natural null-plane projections coming from the γ-algebra and it is shown that the ...
