In this work we study the Dirac equation with vector and scalar potentials in the spacetime
generated by a cosmic string. Using an approximation for the centrifugal term, a solution for …

From a study of an oscillator in a 4D noncommutative (NC) spacetime, we establish the
Hamilton equations of motion. The formers are solved to give the oscillator position and …

In this paper, we analyze the bosonic current densities induced by a magnetic flux running
along the core of an idealized cosmic string in a high-dimensional anti-de Sitter spacetime …

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 …

We study the fermionic condensate (FC) and the vacuum expectation value (VEV) of the
energy-momentum tensor for a massive spinor field in the de Sitter (dS) spacetime including …

The electromagnetic field correlators are evaluated around a cosmic string in background of
(D+ 1)(D+ 1)-dimensional dS spacetime assuming that the field is prepared in the Bunch …

We evaluate the fermion condensate and the expectation values of the charge and current
densities for a massive fermionic field in (2+ 1 2+ 1)-dimensional conical spacetime with a …

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 …

In this manuscript, we study the relativistic quantum mechanics of an electron in external
fields in the spinning cosmic string spacetime. We obtain the Dirac equation and write the …

We study the vacuum polarization effects of the Dirac fermionic field induced by a pointlike
global monopole located in the cosmological de Sitter spacetime. First we derive the four …
