Enhanced Neutrino Cooling from Parity-Doubled Nucleons in Neutron Star Cooling Simulations
Rodrigo Negreiros, Liam Brodie, Jan Steinheimer +2
Although restoration of chiral symmetry is predicted by quantum chromodynamics to take place at high baryon density, most modeling of neutron star interiors disregards a chiral pha…
Thermalization of Neutrinos in a Neutron Star Merger Simulation
Mark G. Alford, Liam Brodie, Francois Foucart +1
We study the neutrino distributions that arise in a simulation of a neutron star merger that uses a Monte Carlo (MC) neutrino transport scheme. In a snapshot taken 1 ms after merge…
Nonparametric extensions of nuclear equations of state: probing the breakdown scale of relativistic mean-field theory
Isaac Legred, Liam Brodie, Alexander Haber +2
Phenomenological calculations of the properties of dense matter, such as relativistic mean-field theories, represent a pathway to predicting the microscopic and macroscopic propert…
Parity-doubled nucleons can rapidly cool neutron stars
Liam Brodie, Robert D. Pisarski
In confined hadronic matter, the spontaneous breaking and restoration of chiral symmetry can be described by considering nucleons, , and excited states of opposite pari…
General-relativistic radiation magnetohydrodynamics simulations of binary neutron star mergers: The influence of spin on the multi-messenger picture
Anna Neuweiler, Henrique Gieg, Henrik Rose +8
The rich phenomenology of binary neutron star mergers offers a unique opportunity to test general relativity, investigate matter at supranuclear densities, and learn more about the…
Neutrino absorption in two-flavor color-superconducting quark matter
Mark G. Alford, Liam Brodie, Michael Buballa +3
We calculate the absorption mean free paths of electron and muon neutrinos in two-flavor color-superconducting (2SC) quark matter in the density and temperature range that is relev…
