Gravitational Waves from Long Strings and Loops
Christos Litos, Sarunas Verner, Wei Xue +1
We compute the gravitational wave spectrum produced by a global cosmic string network in the scaling regime. The spectrum naturally divides at the string correlation length into in…
Heating Up the Black Hole X-ray Binary Accretion Disk by Superradiance
Antonios Kyriazis, Fengwei Yang, Siyu Zhou
A superradiant cloud of ultralight axions around a black hole, that is part of an X-ray binary system, can heat up its accretion disk and be detected by the thermal X-ray spectrum…
Axion Production and Detection Using a Dual NMR-type Experiment
Jeff A. Dror, Qiushi Wei, Fengwei Yang
Axions that couple to nuclear spins via the axial current interaction can be both produced and detected using nuclear magnetic resonance (NMR) techniques. In this scheme, nuclei dr…
Gravitational Waves from Resonant Transitions of Tidally Perturbed Gravitational Atoms
Antonios Kyriazis, Fengwei Yang
Light bosons can form a gravitational atom (GA) around a spinning black hole through the superradiance process. Considering the black hole to be part of a binary system, the tidal…
Indirect Detection of Hot Dark Matter
Jeff A. Dror, Pearl Sandick, Barmak Shams Es Haghi +1
Cosmologically stable, light particles that came into thermal contact with the Standard Model in the early universe may persist today as a form of hot dark matter. For relics with…
Stability of Superconducting Strings
Keisuke Harigaya, Xuce Niu, Wei Xue +1
We investigate the stability of superconducting strings as bound states of strings and fermion zero modes at both the classical and quantum levels. The dynamics of these supercondu…
Gauged Global Strings
Xuce Niu, Wei Xue, Fengwei Yang
We investigate the string solutions and cosmological implications of the gauge global model. With two hierarchical symmetry-breaking scales…
