| Neutron Stars: Cosmic Laboratories to study Matter at extreme Densities |
| Speaker: | Prof. Dr. Ignazio Bombaci (Università di Pisa & INFN Sezione di Pisa) |
| Abstract: | Neutron stars, the compact remnants of core-collapse supernova, are the densest macroscopic objects in the Universe. They represent the limit beyond which gravity overwhelm all the other forces of nature and lead to the formation of a black hole. Neutron stars are thus remarkable natural laboratories that allow us to investigate the fundamental constituents of matter and their interactions under extreme conditions that cannot be reproduced in terrestrial laboratories. In this talk, I will briefly discuss some of the present models to describe the equation of state of dense strongly interacting matter and their application to neutron star physics. In particular, I will focus... [the complete abstract is available here: https://indico.smi.oeaw.ac.at/event/257/] |

| Abstract: | We introduce an analogue of the theory of length spaces into the setting
of Lorentzian geometry and causality theory. The role of the metric is taken
over by the time separation function, in terms of which all basic notions are
formulated. In this way we recover many fundamental results in greater
generality, while at the same time clarifying the minimal requirements for
and the interdependence of the basic building blocks of the theory.
A main focus of this work is the introduction of synthetic curvature bounds,
akin to the theory of Alexandrov and CAT(k)-spaces, based on triangle comparison.
Applications include Lorentzian manifolds with metrics of low regularity, closed cone
structures, and certain approaches to quantum gravity. This is joint work with Michael Kunzinger. Preprint: https://arxiv.org/abs/1711.08990
