קולוקוויום בפיזיקה: Unveiling universality in strongly interacting (nuclear) systems

Zoom: https://us02web.zoom.us/j/84949154008?pwd=aVF0c1FYTUNBbzAyWVVaaE5EZ29TUT09

Abstract: 

From superconductors to atomic nuclei, strongly-interacting many-body systems are ubiquitous in nature. Understanding the relation between the macroscopic properties of such systems and the microscopic particle correlations driving them is an outstanding challenge with wide ranging implications. 

In this talk I will present new studies of correlations between nucleons in atomic nuclei that lead to an emergent universality of strongly interacting systems from dilute atomic gases to neutron stars, spanning over 23 orders of magnitude in density and interaction scales. I will discuss the impact on our understanding of the properties of neutron stars, the core of the strong nuclear interaction, and factorization properties of nuclear wave function. Given time, I will also discuss the implications of these discoveries to open challenges in Quantum Chromodynamics and the nature of confinement.
