How negative can null energy be in large N CFTs?
Jackson R. Fliss, Ben Freivogel, Eleni-Alexandra Kontou +1
Smeared null energy has been shown to be bounded from below for free minimally coupled quantum field theories. This is not the case for conformally coupled free bosonic theories wh…
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…
Mapping 1+1-dimensional black hole thermodynamics to finite volume effects
Jean Alexandre, Drew Backhouse, Eleni-Alexandra Kontou +2
Both black hole thermodynamics and finite volume effects in quantum field theory violate the null energy condition. Motivated by this, we compare thermodynamic features between two…
Wormhole restrictions from quantum energy inequalities
Eleni-Alexandra Kontou
Wormhole solutions, bridges that connect different parts of spacetime, were proposed early in the history of General Relativity. Soon after, it was shown that all wormholes violate…
