On the one-loop effective potential in nonlocal supersymmetric theories
E. R. Bezerra de Mello, F. S. Gama, J. R. Nascimento +1
Within the superfield approach, we consider the nonlocal generalization of the Wess-Zumino model and calculate the one-loop low-energy contributions to the effective action. Four d…
Fermionic vacuum polarization by a magnetic tube in the cosmic string spacetime
M. S. Maior de Sousa, R. Freire Ribeiro, E. R. Bezerra de Mello
In this paper, we consider a charged massive fermionic quantum field in the idealized cosmic string spacetime and in the presence of a magnetic field confined in a cylindrical tube…
Light-Cone Fluctuations in the Cosmic String Spacetime
H. F. Mota, E. R. Bezerra de Mello, C. H. G. Bessa +1
In this paper we consider light-cone fluctuations arising as a consequence of the nontrivial topology of the locally flat cosmic string spacetime. By setting the light-cone along t…
Finite temperature fermion condensate, charge and current densities in a (2+1)-dimensional conical space
S. Bellucci, E. R. Bezerra de Mello, E. Bragança +1
We evaluate the fermion condensate and the expectation values of the charge and current densities for a massive fermionic field in (2+1)-dimensional conical spacetime with a magnet…
