Title: “Higgs-Confinement Transitions in QCD from Symmetry Protected Topological Phases” Abstract: In gauge theories with fundamental matter, such as QCD, there is typically no sharp way to distinguish confining and […]
Title: de Sitter as an Axion Detector Abstract: Axions, scalar fields with compact field spaces, are some of the most well-motivated candidates for physics beyond the Standard Model. In this […]
Title: "Towards Dark Ages with LuSEE-Night" plus "large scale isocurvature fluctuations and the Hubble tension"
Title: Gravitational Wave Symphony from Oscillating Spectator Scalar Fields Abstract: Spectator scalar fields can be generically present in the early Universe, and are potentially dark matter candidates. We investigate the […]

TITLE: Impact of primordial magnetic fields on matter power spectrum ABSTRACT: Primordial magnetic fields (PMFs) offer a simple explanation for the origin of galactic magnetic fields as well as of […]
TITLE: CMB limits on decaying dark matter: going beyond the ionization threshold ABSTRACT: The temperature and polarization anisotropies of the cosmic microwave background (CMB) have been used to set constraints […]
Title: Binary black hole waveforms in the small mass ratio limit Abstract: Current gravitational-wave detectors are being upgraded, and plans are developing for future detectors with greater sensitivity over broader […]
TITLE: Studying the Extreme Universe with Imaging Atmospheric Cherenkov Telescopes, ABSTRACT: The night sky is filled with flashes of blue "Cherenkov" light, which last for just a few billionths of […]
TITLE: Revisiting the axion-electron coupling ABSTRACT: In the presence of axion dark matter, fermion spins experience an “axion wind” torque and an “axioelectric” force. We investigate new experimental probes of these […]
TITLE: Ghosts on the way to a QFT for gravity ABSTRACT: Ghosts have been a stumbling block in the development of a UV complete quantum field theory for gravity. We […]
