Current density induced by a cosmic string in de Sitter spacetime in the presence of two flat boundaries
W. Oliveira dos Santos, H. F. Santana Mota, E. R. Bezerra de Mello
In this paper, we investigate the vacuum bosonic current density induced by a carrying-magnetic-flux cosmic string in a -de Sitter spacetime considering the presence of two…

Induced fermionic current in AdS spacetime in the presence of a cosmic string and a compactified dimension
S. Bellucci, W. Oliveira dos Santos, E. R. Bezerra de Mello
In this paper, we consider a massive charged fermionic quantum field and investigate the current densities induced by a magnetic flux running along the core of an idealized cosmic…

Induced current in high-dimensional AdS spacetime in the presence of a cosmic string and a compactified extra dimension
W. Oliveira dos Santos, H. F. Mota, E. R. Bezerra de Mello
In this paper, we analyse the bosonic current densities induced by a magnetic flux running along the core of an idealized cosmic string in a high-dimensional AdS spacetime, admitti…
