Framework for phase transitions between the Maxwell and Gibbs constructions at finite temperature
Constantinos Constantinou, Mirco Guerrini, Tianqi Zhao +2
The characteristics of the hadron-to-quark first-order phase transition differ depending on whether charge neutrality is locally or globally fulfilled. In -equilibrated matter,…
Role of thermal fluctuations in nucleation of three-flavor quark matter
Mirco Guerrini, Giuseppe Pagliara, Andrea Lavagno +1
We present a framework that aims to investigate the role of thermal fluctuations of the matter composition and color-superconductivity in the nucleation of three-flavor deconfined…
Detecting the third family of compact stars with normalizing flows
Valéria Carvalho, Márcio Ferreira, Constança Providência +1
We explore the anomaly detection framework based on Normalizing Flows (NF) models introduced in \cite{PhysRevC.106.065802} to detect the presence of a large (destabilising) dense m…
Conditional variational autoencoder inference of neutron star equation of state from astrophysical observations
Márcio Ferreira, Michał Bejger
We present a new inference framework for neutron star astrophysics based on conditional variational autoencoders. Once trained, the generator block of the model reconstructs the ne…
Bjorken flow revisited: analytic and numerical solutions in flat space-time coordinates
Daniele Simeoni, Alessandro Gabbana, Sauro Succi
In this work we provide analytic and numerical solutions for the Bjorken flow, a standard benchmark in relativistic hydrodynamics providing a simple model for the bulk evolution of…
Was GW190814 a black hole -- strange quark star system?
I. Bombaci, A. Drago, D. Logoteta +2
We investigate the possibility that the low mass companion of the black hole in the source of GW190814 was a strange quark star. This possibility is viable within the so-called two…
