The double smeared null energy condition

Jackson R. Fliss, Ben Freivogel, Eleni-Alexandra Kontou

The null energy condition (NEC), an important assumption of the Penrose singularity theorem, is violated by quantum fields. The natural generalization of the NEC in quantum field t…

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…

A semiclassical singularity theorem

Christopher J. Fewster, Eleni-Alexandra Kontou

Quantum fields do not satisfy the pointwise energy conditions that are assumed in the original singularity theorems of Penrose and Hawking. Accordingly, semiclassical quantum gravi…

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…
