Primordial magnetic field from chiral plasma instability with sourcing
Murman Gurgenidze, Andrew J. Long, Alberto Roper Pol +2
In an electron-positron plasma, an imbalance in the number of right- and left-chiral particles can lead to the growth of a helical magnetic field through a phenomenon called the ch…
Creation of spin-3/2 dark matter via cosmological gravitational particle production
Edward W. Kolb, Andrew J. Long, Evan McDonough +1
We study the cosmological gravitational particle production (CGPP) of spin-3/2 particles during and after cosmic inflation, and map the parameter space that can realize the observe…
Towards the Direct Detection of Composite Ultraheavy Dark Matter in Quantum Sensor Arrays
Dorian W. P. Amaral, Erqian Cai, Andrew J. Long +2
Quantum sensor arrays have recently been proposed as a promising platform for the direct detection of ultraheavy dark matter, which is typically assumed to behave as a point-like p…
