Nonthermal fixed points in quantum field theory beyond the weak-coupling limit
(American Physical SocietyPhysical Review D - Particles, Fields, Gravitation and Cosmology, 2017-02-22)
Quantum systems in extreme conditions can exhibit universal behavior far from equilibrium associated to nonthermal fixed points with a wide range of topical applications from early-Universe inflaton dynamics and heavy-ion ...
New Target for Cosmic Axion Searches
(American Physical SocietyPhysical Review Letters, 2016-10-20)
Future cosmic microwave background experiments have the potential to probe the density of relativistic species at the subpercent level. This sensitivity allows light thermal relics to be detected up to arbitrarily high ...
