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…
