  Observation of the axion quasiparticle in 2D MnBi₂Te₄

  The axion is a hypothetical fundamental particle that is conjectured to correspond to the coherent oscillation of the θ field in quantum chromodynamics. Its existence would solve multiple fundamental questions, […]

  Observing Leptogenesis in Action with Gravitational Waves

  Leptogenesis is arguably the best motivated theory of baryogenesis given the discovery of finite neutrino masses, yet its experimental test is elusive given its high energy scale. We discuss gravitational […]

  The Secret Life of Neutrinos

  Neutrinos are cosmic tricksters, paradoxically hardly there but lethal to stars significantly more massive than the sun.

  Nonconservation of Lepton Numbers in the Neutrino Sector Could Change the Prospects for Core Collapse Supernova Explosions

  We show that interactions violating the conservation of lepton numbers in the neutrino sector could significantly alter the standard low entropy picture for the presupernova collapsing core of a massive […]

  2νββ spectrum in chiral effective field theory

  We investigate two-neutrino double beta decay (2νββ) in chiral effective field theory. We find contributions from weak magnetism and double-weak pion-exchange at next-to-leading-order in the chiral power counting. We discuss […]
