Overview • QFTCST in an extension of standard Minkowski space QFT. • This is a huge topic. • Particle interpretation depends on the observer. • No way to define a canonical vacuum state. • Some interesting applications like Hawking Radiation
Basic Formalism • The Lagrangian (EOM) of the classical theory. • A quantization procedure. • The characterization of the quantum states. • The physical interpretation of the states (observables). We will discuss in the context of a particular model theory
The Hawking Effect • Apply the notions of particle creation by gravitational field to black hole spacetime. • Concentrate on the case of massless scalar field in the Schwarzschild spacetime. • We’ll ignore the derivation and only present some interesting conclusion for the sake of our interest.
