Axion Quality Problem: Keep Calm and Baryon
Prateek Agrawal, Anson Hook, Vazha Loladze +1
Axion models generically suffer from a severe quality problem when coupled to gravity. In this article we provide a very simple model with a high quality axion. The axion is a pseu…
Dynamics of the Fermion-Rotor System
Vazha Loladze, Takemichi Okui, David Tong
We explore the dynamics of the fermion-rotor system, a simple impurity model in d=1+1 dimensions that consists of a collection of purely right-moving fermions interacting with a qu…
Prediction for Maximum Supercooling in SU(N) Confinement Transition
Prateek Agrawal, Gaurang Ramakant Kane, Vazha Loladze +1
The thermal confinement phase transition (PT) in Yang-Mills theory is first-order for , with bounce action scaling as . Remarkably, lattice data for the actio…
Supercooled Confinement
Prateek Agrawal, Gaurang Ramakant Kane, Vazha Loladze +1
We study general properties of confinement phase transitions in the early universe. An observable gravitational wave signal from such transitions requires significant supercooling.…
Higher Axion Strings
Vazha Loladze, Arthur Platschorre, Mario Reig
We study the minimal requirements to obtain axion strings for axions with exponentially good quality. These ingredients appear in theories where an axion coming from a higher-form…
