A grounded perspective on New Early Dark Energy using ACT, SPT, and BICEP/Keck
Juan S. Cruz, Florian Niedermann, Martin S. Sloth
We examine further the ability of the New Early Dark Energy model (NEDE) to resolve the current tension between the Cosmic Microwave Background (CMB) and local measurements of $H_0…
Instability of bubble expansion at zero temperature
Wen-Yuan Ai, Juan S. Cruz, Bjorn Garbrecht +1
In the context of false vacuum decay at zero temperature, it is well known that bubbles expand with uniform proper acceleration. We show that this uniformly accelerating expansion…
The limits of the strong problem
Wen-Yuan Ai, Juan S. Cruz, Bjorn Garbrecht +1
While violation has never been observed in the strong interactions, the QCD Lagrangian admits a -odd topological interaction proportional to the so called angle, which…
Quantum and Gradient Corrections to False Vacuum Decay on a de Sitter Background
Juan S. Cruz, Stephan Brandt, Maximilian Urban
We study the effects of a fixed de Sitter geometry background in scenarios of false vacuum decay. It is currently understood that bubble nucleation processes associated with first…
