Axions and Primordial Magnetogenesis: the Role of Initial Axion Inhomogeneities
Filippo Anzuini, Angelo Maggi
The relic density of dark matter in the CDM model restricts the parameter space for a cosmological axion field, constraining the axion decay constant, the initial amplitude of t…
Axion sourcing in dense stellar matter via CP-violating couplings
Filippo Anzuini, Antonio Gómez-Bañón, José A. Pons +2
Compact objects such as neutron stars and white dwarfs can source axion-like particles and QCD axions due to CP-violating axion-fermion couplings. The magnitude of the axion field…
Magnetic dynamo caused by axions in neutron stars
Filippo Anzuini, José A. Pons, Antonio Gómez-Bañón +3
The coupling between axions and photons modifies Maxwell's equations, introducing a dynamo term in the magnetic induction equation. In neutron stars, for critical values of the axi…
Thermal luminosity degeneracy of magnetized neutron stars with and without hyperon cores
F. Anzuini, A. Melatos, C. Dehman +2
The dissipation of intense crustal electric currents produces high Joule heating rates in cooling neutron stars. Here it is shown that Joule heating can counterbalance fast cooling…
Fast cooling and internal heating in hyperon stars
F. Anzuini, A. Melatos, C. Dehman +2
Neutron star models with maximum mass close to reach high central densities, which may activate nucleonic and hyperon direct Urca neutrino emission. To alleviate th…
Gradient expansion technique for inhomogeneous, magnetized quark matter
Filippo Anzuini, Andrew Melatos
A quark-magnetic Ginzburg-Landau (qHGL) gradient expansion of the free energy of two-flavor inhomogeneous quark matter in a magnetic field is derived analytically. It can be ap…
Differential rotation in neutron stars with open and closed magnetic topologies
F. Anzuini, A. Melatos
Analytic arguments have been advanced that the degree of differential rotation in a neutron star depends on whether the topology of the internal magnetic field is open or closed. T…
Crystalline phases by an improved gradient expansion technique
Stefano Carignano, Filippo Anzuini, Omar Benhar +1
We develop an innovative technique for studying inhomogeneous phases with a spontaneous broken symmetry. The method relies on the knowledge of the exact form of the free energy in…
