Holographic entropy bound from gravitational Fock space truncation
Andreas Aste
A simplified derivation of Yurtsever's result, which states that the entropy of a truncated bosonic Fock space is given by a holographic bound when the energy of the Fock states is…

Fock Vacuum Instability and Causality
Andreas Aste
The vacuum diagram is calculated at second order for theories with self-interacting massless fields in the framework of finite causal perturbation theory. It is pointed out that th…

Power counting degree versus singular order in the Schwinger model
Andreas Aste, G"unter Scharf, Urs Walther
The importance of a rigorous definition of the singular degree of a distribution is demonstrated on the case of two-dimensional QED (Schwinger model). Correct mathematical treatmen…
