Associated scholarship(s):18/09575-0 - Vacuum Fluctuations in non-globally hyperbolic spacetimes, BE.EP.MS


The main purpose of this project is to study quantum field theory in non-globally hyperbolic spacetimes within its application in an specific example. This example consists of establishing the quantum fluctuations around a global monopole as a function of the boundary conditions necessary for the physical evolution of scalar fields in this classically singular background. The applicant should study quantum field theory in curved spacetime an apply the techniques of renormalization of the energy-momentum tensor in a non-globally hyperbolic spacetime. We note that it is a current research subject and we hope that the applicant could contribute to this line of research by presenting new results in an extremely important example. (AU)
