    LIGHT AND AIRY: A SIMPLE SOLUTION FOR RELATIVISTIC QUANTUM ACCELERATION RADIATION
    (Universe, 2021-03-05) Good, Michael R. R.; Linder, Eric V.
    We study the quantum radiation of particle production by vacuum from an ultra-relativistic moving mirror (dynamical Casimir effect) solution that allows (possibly for the first time) analytically calculable time evolution of particle creation and an Airy particle spectral distribution. The reality of the beta Bogoliubov coefficients is responsible for the simplicity, and the mirror is asymptotically inertial at the speed of light, with finite energy production. We also discuss general relations regarding negative energy flux, the transformation to the 1-D Schrödinger equation, and the incompleteness of entanglement entropy.

    UPON THE HORIZON'S VERGE: THERMAL PARTICLE CREATION BETWEEN AND APPROACHING HORIZONS
    (Classical and Quantum Gravity, 2022) Fernández-Silvestre, Diego; Good, Michael R R; Linder, Eric V
    Quantum particle creation from spacetime horizons, or accelerating boundaries in the dynamical Casimir effect, can have an equilibrium, or thermal, distribution. Using an accelerating boundary in flat spacetime (moving mirror), we investigate the production of thermal energy flux despite non-equilibrium accelerations, the evolution between equilibrium states, and the ‘interference’ between horizons. In particular, this allows us to give a complete solution to the particle spectrum of the accelerated boundary correspondence with Schwarzschild–de Sitter spacetime.
