A new approach in classical Klein-Gordon cosmology: "Small Bangs", inflation and Dark Energy

Eleni-Alexandra Kontou, Nicolai Rothe

In this work, we analyze the cosmological model in which the expansion is driven by a classical, free Klein-Gordon field on a flat, four-dimensional Friedmann-Lemaître-Robertson-Wa…

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…

Modeling the microlensing of circumbinary systems

Brett George, Eleni-Alexandra Kontou, Patrycja Przewoznik +1

Gravitational microlensing is one of the methods to detect exoplanets; planets outside our solar system. Here we focus on theoretical modeling of three lens systems and in particul…

Eternal inflation, energy conditions and the role of decoherent histories

Eleni-Alexandra Kontou, Ken D. Olum

Eternal inflation, the idea that there is always a part of the universe that is expanding exponentially, is a frequent feature of inflationary models. It has been argued that etern…

Energy conditions allow eternal inflation

Eleni-Alexandra Kontou, Ken D. Olum

Eternal inflation requires upward fluctuations of the energy in a Hubble volume, which appear to violate the energy conditions. In particular, a scalar field in an inflating spacet…

Energy conditions in general relativity and quantum field theory

Eleni-Alexandra Kontou, Ko Sanders

This review summarizes the current status of the energy conditions in general relativity and quantum field theory. We provide a historical review and a summary of technical results…
