In this talk, I will present an analysis of the first excited state of 4He within a coupled-channels formalism in Halo EFT. This state lies between two 3+1 channels and is likely associated with a four-body excited Efimov state exhibiting a 3+1 halo structure.
The projectile's low breakup threshold significantly impacts fusion dynamics, making precise predictions of CF and ICF cross sections a major theoretical challenge.
We derive the universal functional form of the three-body renormalization relation for general separable regulators through a detailed analysis of the Skorniakov-Ter-Martirosian and Faddeev equations.
We study helium-4 clusters using effective field theory, computing their binding energies with quantum Monte Carlo methods. The results highlight universal features of strongly interacting systems.
In this talk, I present a phenomenological extension of halo-EFT and a more formal EFT-like study that include core excitation effects. Results for Be, C and C will be shown.
I will discuss the basics of particle-momentum correlations in heavy-ion collisions, giving an introduction to the origins of the technique and showing its application to some simple physical systems. In doing so, we will explore the phenomenological behavior of correlation functions and touch on current challenges in the field. The topic is especially interesting as it provides insight into...
Efimov universality describes three-body systems near unitarity, where large scattering lengths make their properties essentially independent of short-range interaction details. This regime is marked by discrete scale invariance, reflected in a geometric spectrum of trimers. In ultracold atomic gases, external magnetic fields allow precise tuning of interactions to the resonant regime, while...
