The creation of kappa deformed electromagnetic radiation from a sum of zero modes
M. V. Cougo-Pinto, J. F. M. Mendes, C. Farina
In a related paper we have obtained that the effective action for a kappa-deformed quantum field theory has a real and an imaginary part. The real part is half the sum of the kappa…

The relation between effective action and vacuum energy in a kappa-deformed theory
M. V. Cougo-Pinto, J. F. M. Mendes, C. Farina
In a quantum field with spacetime invariance governed by the Poincare algebra the one-loop effective action is equal to the sum of zero modes frequencies, which is the vacuum energ…
