Query: Nonperturbative Quantum Field Theory in Astrophysics   The extreme electromagnetic or gravitational fields associated with some
astrophysical objects can give rise to macroscopic effects arising from the
physics of the quantum vacuum. Therefore, these objects are incredible
laboratories for exploring the physics of quantum field theories. In this
dissertation, we explore this idea in three astrophysical scenarios.
