A rotation in Peccei-Quinn field space along the axion direction can address cosmological mysteries, including dark matter, baryon asymmetry, cosmic perturbations, and the Hubble tension. This dynamics may naturally arise as a result of quantum gravity effects and cosmic inflation. Axion rotations can simultaneously give a new origin of axion dark matter via kinetic misalignment and generate...
Low mass accelerated dark matter (DM) is very well motivated and has been a subject of much attention in the literature. These fast-moving particles can gain enough kinetic energy to surpass the energy thresholds of some Large volume terrestrial detectors. For instance, fast-moving DM can deposit sizable amounts of energy at both large volume neutrino detectors and dark matter direct detection...
