NANOGrav meets Hot New Early Dark Energy and the origin of neutrino mass
Juan S. Cruz, Florian Niedermann, Martin S. Sloth
It has recently been speculated that the NANOGrav observations point towards a first-order phase transition in the dark sector at the GeV scale [1]. Here, we show that such a phase…
Cold New Early Dark Energy pulls the trigger on the and tensions: a simultaneous solution to both tensions without new ingredients
Juan S. Cruz, Florian Niedermann, Martin S. Sloth
In this work, we show that the Cold New Early Dark Energy (Cold NEDE) model in its original form can solve both the Hubble tension and the tension without adding any new ingr…
Profiling Cold New Early Dark Energy
Juan S. Cruz, Steen Hannestad, Emil Brinch Holm +3
Recent interest in New Early Dark Energy (NEDE), a cosmological model with a vacuum energy component decaying in a triggered phase transition around recombination, has been sparked…
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…
Gradient effects on false vacuum decay in gauge theory
Wen-Yuan Ai, Juan S. Cruz, Bjorn Garbrecht +1
We study false vacuum decay for a gauged complex scalar field in a polynomial potential with nearly degenerate minima. Radiative corrections to the profile of the nucleated bubble…
Absence of violation in the strong interactions
Wen-Yuan Ai, Juan S. Cruz, Bjorn Garbrecht +1
We derive correlation functions for massive fermions with a complex mass in the presence of a general vacuum angle. For this purpose, we first build the Green's functions in the on…
