On behalf of the “Espace de Structure et de réactions Nucléaires Théorique” (ESNT), the workshop entitled: “Many-body correlations, phase transitions, and clustering: how to identify and quantify them?” will be held at CEA-Saclay, Orme-des-Merisiers site.
Talks and seminars are organized during the first week (7-11 September).
The structure of atomic nuclei reflects a delicate interplay between single-particle motion and collective correlations. Phenomena such as pairing, shape coexistence and clustering exemplify how complex emergent behavior arises from fundamental nucleon–nucleon interactions.
In recent years, major progress has been achieved in ab initio, shell-model, and energy-density functional approaches, as well as through advanced experimental probes. However, the field still lacks unified diagnostics capable of quantifying the degree of collectivity, correlation, and condensation in a model-independent manner.
Goals of the workshop
(i) To discuss how correlations and clusterisations are treated in various models and how they manifest in experimental data.
(ii) To discuss how to identify and to quantify, theoretically and experimentally, the emergence of quantum phase transitions associated to pairing and alpha-like condensation.
(iii) To explore the methods employed to describe correlations, phase transitions and condensation in condensed matter superfluidity, ultracold gases and quantum information, and to discuss how they can be applied to nuclear systems.
