Abstract: The atomic nucleus is composed of two different kinds of fermions: protons and neutrons. While most theories treat nucleons as single particles moving in a mean‐field potential, recent hig henergy proton and electron scattering experiments show that short range interactions between the nucleons form correlated, high momentum, neutron‐proton pairs, known as Short‐Range Correlations (SRC). The existence and exact properties of such correlations account for 20% of the nucleons in the nucleus and have wide ranging implications to topics in particle and astro physics.
In this talk I will overview the experimental studies of SRC in nuclei and ultra‐cold atomic gasses. I will present an intriguing equivalence between the systems used it to derive a new theoretical description of atomic nuclei, using an asymptotic formalism developed to describe ultra‐cold atomic gasses. This first successful use of atomic theory in nuclei may lead the way to simulate certain aspects of nuclei and atomic traps. Given time, I will also present the application of this formalism to nuclear related issues in particle physics and astrophysics.
