Questions d'examen pour l'examen virtuel

1. What are the main steps when one builds the quantum theory of a scalar field in an expanding flat universe. What are the consequences, especially in the case of exponential growth?
2. What is the basis of the derivation of the Unruh temperature? Explain what transformations relate the inertial system to the accelerated one.
3. Enumerate the changes of variables needed to derive the Szekeres coordinates. How does one relate the vacuum in the Schwarzschild coordinates to the vacuum in the Szekeres coordinates? Define the Hawking temperature.
4. Explain the basic laws of the thermodynamics of black holes.
5. Explain the basic principles of inflation and give an example.
