Thermal Casimir effect in the Einstein Universe with a spherical boundary
Herondy F. S. Mota, Celio R. Muniz, Valdir B. Bezerra
In the present paper we investigate thermal fluctuation corrections to the vacuum energy at zero temperature of a conformally coupled massless scalar field whose modes propagate in…
Boundary effects on classical liquid density fluctuations
K. E. L. de Farias, Azadeh Mohammadi, Herondy F. Santana Mota
In this paper, we study quantum vacuum fluctuation effects on the mass density of a classical liquid arising from the conical topology of an effective idealized cosmic string space…
Thermal Casimir effect for the scalar field in flat spacetime under a helix boundary condition
Giulia Aleixo, Herondy Mota
In this work we consider the generalized zeta function method to obtain temperature corrections to the vacuum (Casimir) energy density, at zero temperature, associated with quantum…

Light-Cone Fluctuations in the Cosmic String Spacetime
H. F. Mota, E. R. Bezerra de Mello, C. H. G. Bessa +1
In this paper we consider light-cone fluctuations arising as a consequence of the nontrivial topology of the locally flat cosmic string spacetime. By setting the light-cone along t…
Noninertial effects on the ground state energy of a massive scalar field in the cosmic string spacetime
