Title: Vacuum particle creation and back-reaction effect in moving mirror models

Abstract: The interaction between black hole and quantum field is thought to be one of the promising labs studying the building blocks of the spacetime. With the help of general covariance principle, the Hawking radiation of a black hole can be analogy to the dynamical Casimir effect from an accelerating mirror in Minkowski spacetime. In this talk, I will discuss three problems of dynamical Casimir effect. 1. How the bare mass of the field quanta affects the vacuum radiation and vacuum friction force on semi-classical level. 2. In full quantum regime how the quantum fluctuation of the mirror gives quantum corrections to the dynamical Casimir effect. 3. Landauer’s principle of Fermionic field interacting with an Unruh-DeWitt detector.
