Ground State Energy of Massive Scalar Field Inside a Spherical Region in the Global Monopole Background
E. R. Bezerra de Mello, V. B. Bezerra, N. R. Khusnutdinov
Using the zeta function regularization method we calculate the ground state energy of scalar massive field inside a spherical region in the space-time of a point-like global monopo…
Relativistic Quantum Scattering on a Cone
J. Spinelly, E. R. Bezerra de Mello, V. B. Bezerra
We study the relativistic quantum mechanical scattering of a bosonic particle by an infinite straight cosmic string, considering the non-minimal coupling between the bosonic field…
Vaccum Polarization for a Massless Scalar Field in the Global Monopole Spacetime at Finite Temperature
F. C. Carvalho, E. R. Bezerra de Mello
In this paper we calculate the effects produced by temperature in the renormalized vaccum expectation value of the square of the massless scalar field in the pointlike global monop…
