Constraining axion quadratic couplings with the Hulse-Taylor binary system
Ziwen Yin, Shyam Balaji, Malcolm Fairbairn +1
The orbital evolution of the Hulse-Taylor binary neutron star system is described to high precision by general relativity, in which gravity is the only long-range force and gravita…
Solving Einstein Field Equations on a Digital Quantum Computer
Clelia Altomonte, Malcolm Fairbairn
In this work, we show how simulations performed on classical computers such as those of Numerical Relativity can be tackled by quantum algorithms for solving systems of partial dif…
Phenomenology of Vector Dark Matter produced by a First Order Phase Transition
Malcolm Fairbairn, William S. A. Shellard
Both scalar and vector dark matter can be produced during a cosmological first order phase transition if the dark matter is coupled to the field undergoing the transition. Both kin…
Non-thermal production of heavy vector dark matter from relativistic bubble walls
Wen-Yuan Ai, Malcolm Fairbairn, Ken Mimasu +1
Heavy vector boson dark matter at the TeV scale or higher may be produced non-thermally in a first-order phase transition taking place at a lower energy scale. While the production…
Dwarf galaxies imply dark matter is heavier than
Tim Zimmermann, James Alvey, David J. E. Marsh +2
It is widely established that a lower bound on the dark matter particle mass, , can be obtained by demanding that the de Broglie wavelength in a given galaxy must be smaller tha…
