A singularity theorem for evaporating black holes
Eleni-Alexandra Kontou, Ben Freivogel, Dimitrios Krommydas
The classical singularity theorems of General Relativity rely on energy conditions that are easily violated by quantum fields. Here, we provide motivation for an energy condition o…

The Smeared Null Energy Condition
Ben Freivogel, Dimitrios Krommydas
We propose a new bound on the average null energy along a finite portion of a null geodesic. We believe our bound is valid on scales small compared to the radius of curvature in an…

Violations of the Null Energy Condition in QFT and their Implications
Dimitrios Krommydas
We study violations of the Null Energy Condition (NEC) in Quantum Field Theory (QFT) and their implications. For the first part of the project, we examine these violations for clas…
