  Pulsar Timing Sensitivity to Dark Matter Substructure in the Presence of a Stochastic Gravitational-Wave Background

  Pulsar timing arrays (PTAs) can detect dark matter (DM) substructure through the small shifts a transiting DM subhalo imprints on pulse arrival times. Recently found evidence for a stochastic gravitational-wave […]

  Hunting Dark Matter with Atom Gradiometers

  Dark matter is one of the deepest mysteries in fundamental physics. While the existence of dark matter has been robustly established over the past decades through a combination of astronomical (e.g. the rotation of galaxies, the Bullet Cluster) and cosmological (e.g. anisotropies in the cosmic microwave background) observations, we still do not know what it is made of.

  Collective neutrino oscillations: Many-body non-forward effects and non-classicality

  Neutrino evolution in dense astrophysical environments is typically described either within a quantum kinetic framework, which neglects the build-up of multi-body correlations, or through simplified many-body calculations that allow significant […]

  Neutrino helicity oscillations in astrophysical environments: a many-body approach

  Neutrino rest mass enables left-handed states to “flip” to right-handed states and vice versa. In-medium effects can enhance the probability for such spin-flip. We demonstrate that a full many-body calculation […]
