In this thesis, we investigate quantum properties associated with massive fields near a cosmic string within two distinct scenarios: a Minkowski flat background, and a maximally symmetric anti-de Sitter spacetime (AdS). Initially, we present a brief review of the formalism needed in our contribution. In Minkowski spacetime, we analyze the relativistic quantum dynamics of bosonic and fermionic charged particles in the presence of a magnetic field also considering the presence of scalar potentials. In order to develop this analysis, we assume that the magnetic field is parallel to the string axis, and the scalar potentials present a cylindrical symmetry with their center on the string. Two distinct configurations for the scalar potential are ...
