@inproceedings{Bellucci2021TopologicalEI, title={Topological effects in fermion condensate induced by cosmic string and compactification on AdS bulk}, author={Stefano Bellucci and W. Oliveira dos Santos and E. R. Bezerra Mello and A. A. Saharian}, year={2021} }

We investigate the fermion condensate (FC) for a massive spinor field on background of the 5-dimensional locally anti-de Sitter (AdS) spacetime with a compact dimension and in the presence of a cosmic string carrying a magnetic flux. The FC is decomposed into two contributions. The first one corresponds to the geometry without compactification and the second one is induced by the compactification. Depending on the values of the parameters, the total FC can be either positive or negative. As a… Expand
