Spin-dependent dark matter scattering in quasi-two-dimensional magnets
Giacomo Marocco, John Wheater
We study the prospects of detecting dark matter coupled to the spin of the electron, such that it may scatter and excite magnons - collective excitations of electronic spins. We sh…

Dark photon limits from magnetic fields and astrophysical plasmas
Giacomo Marocco
Dark photons may kinetically mix with our photon and modify Maxwell's equations. We examine their impact on the Lorentz force acting on the plasma in astrophysical magnetospheres.…
