Entanglement Entropy of Massive Scalar Fields: Mass Suppression, Violation of Universal mR Scaling, and Implications for Black Hole Thermodynamics
S. Bellucci, M. Shatnev, L. Zazunov
We investigate the entanglement entropy of a massive scalar field using the spherical shell lattice model introduced by Das and Shankaranarayanan. A systematic numerical analysis i…
Vacuum fermionic currents in braneworld models on AdS bulk with a cosmic string
S. Bellucci, W. Oliveira dos Santos, E. R. Bezerra de Mello +1
We investigate the effects of a brane and magnetic-flux-carrying cosmic string on the vacuum expectation value (VEV) of the current density for a charged fermionic field in the bac…
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…
The Casimir effect for fermionic currents in conical rings with applications to graphene ribbons
S. Bellucci, I. Brevik, A. A. Saharian +1
We investigate the combined effects of boundaries and topology on the vacuum expectation values (VEVs) of the charge and current densities for a massive 2D fermionic field confined…
Induced fermionic charge and current densities in two-dimensional rings
S. Bellucci, A. A. Saharian, A. Kh. Grigoryan
For a massive quantum fermionic field, we investigate the vacuum expectation values (VEVs) of the charge and current densities induced by an external magnetic flux in a two-dimensi…
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…
