Effective action in DSR1 quantum field theory
M V Cougo-Pinto, C Farina, F S S Rosa +1
We present the one-loop effective action of a quantum scalar field with DSR1 space-time symmetry as a sum over field modes. The effective action has real and imaginary parts and ma…
Dynamical Casimir effect with Robin boundary conditions
B. Mintz, C. Farina, P. A. Maia Neto +1
We consider a massless scalar field in 1+1 dimensions that satisfies a Robin boundary condition at a non-relativistic moving boundary. Using the perturbative approach introduced by…
Path Integral and the Induction Law
F. A. Barone, C. Farina
We show how the induction law is correctly used in the path integral computation of the free particle propagator. The way this primary path integral example is treated in most text…
The Zeta Function Method and the Harmonic Oscillator Propagator
F. A. Barone, C. Farina
We show how the pre-exponential factor of the Feynman propagator for the harmonic oscillator can be computed by the generalized -function method. Besides, we establish a direct…
On The Influence of Two Parallel Plates on Atomic Levels
D. T. Alves, F. A. Barone, C. Farina +1
This paper is devoted to the study of the influence of two parallel plates on the atomic levels of a Hydrogen atom placed in the region between the plates. We treat two situations,…
