Drilling Inside A Neutron Star With A Computer
abstract
eutron stars (NS) have come to the general attention after the recent joint observation of gravitational
waves and electromagnetic signals from a collision event. A detailed understanding of these phenomena
requires the knowledge of the internal structure of the star. How can we drill inside it? Computational
many-body methods can help us overcoming this problem. In the talk I will overview some of the recent
progress in understanding NS made by means of accurate imaginary time projection Quantum Monte Carlo
(QMC) calculations. Some of the relevant applications of these techniques to the neutron star physics will
be illustrated, beginning with the neutron matter equation of state, which determines the overall structural
properties of the star, the behavior of matter at densities above saturation (with the possible appearance
of hyperons in the inner core of the star) as inferred from terrestrial experiments, and some response
properties relevant for the interaction with neutrinos
