Particle Creation in a Cosmological Background in Analogy to the Schwinger Effect
Walter D. van Suijlekom, Michael F. Wondrak, Heino Falcke
We consider a gravitational analogue of the Schwinger effect in a cosmological context. While the Schwinger effect is usually attributed to a static electric background, its deriva…

Convergence of spectral truncations for compact metric groups
Yvann Gaudillot-Estrada, Walter D. van Suijlekom
We consider Gromov-Hausdorff convergence of state spaces for spectral truncations of a compact metric group . We work in the context of order-unit spaces and consider orthogonal…

Reply to "Comment on 'Gravitational Pair Production and Black Hole Evaporation'"
Michael F. Wondrak, Walter D. van Suijlekom, Heino Falcke
In a recent letter, the authors presented a unified derivation of the electric Schwinger effect and a generalized Hawking effect with an additional radiation component. The approac…
