Photon Mass and Very Long Baseline Interferometry
A. Accioly, J. Helayël-Neto, E. Scatena
A relation between the photon mass, its frequency, , and the deflection parameter, , determined by experimentalists (which characterizes the contribution of space curvature t…
Algorithm for Probing the Unitarity of Topologically Massive Models
Antonio Accioly, Marco Dias
An uncomplicated and easily handling prescription that converts the task of checking the unitarity of massive, topologically massive, models into a straightforward algebraic exerci…
Is it Physically Sound to Add a Topologically Massive Term to Three-Dimensional Massive Electromagnetic or Gravitational Models ?
Antonio Accioly, Marco Dias
The addition of a topologically massive term to an admittedly non-unitary three-dimensional massive model, be it an electromagnetic system or a gravitational one, does not cure its…
Boson-boson effective nonrelativistic potential for higher-derivative electromagnetic theories in D dimensions
Antonio Accioly, Marco Dias
The problem of computing the effective nonrelativistic potential for the interaction of charged scalar bosons within the context of D-dimensional electromagnetism with a cu…
Unavoidable Conflict Between Massive Gravity Models and Massive Topological Terms
Antonio Accioly, Marco Dias
Massive gravity models in 2+1 dimensions, such as those obtained by adding to Einstein's gravity the usual Fierz-Pauli, or the more complicated Ricci scalar squared (), terms,…
