[Theory-seminars] Theory Seminar Monday

[Joseph Karpie]

Hey everyone,

Please join us in on Monday at 1pm in L102 for a Theory seminar from Xilin Zhang (FRIB/MSU).

Title: Recent Advances in Nuclear Continuum Theory and Computation

Abstract: the nuclear continuum theory is foundational to low-energy nuclear physics, elucidating reaction dynamics probed at facilities like the Facility for Rare Isotope Beams and supporting fields such as nuclear astrophysics. This subject also shares a close theoretical foundation with hadronic continuum physics, a connection I will explore in this talk.

My primary focus is to introduce several developments from my own work in low-energy nuclear continuum physics. I will present two ab initio methods (2004.13575, 2408.03309) developed to extend continuum calculations across the nuclear chart, where such efforts are currently confined to light systems. These developments have yielded fresh insights into general continuum physics and offered new perspectives on computational strategies that may prove relevant to the hadronic physics community.

A second topic is the development of emulators (or surrogate models) for continuum calculations (2007.03635, 2110.04269), a powerful tool for dramatically reducing computational costs in tasks like model calibration and uncertainty quantification. I will speculate on their potential application in hadronic physics and invite the audience to explore these parallels. Finally, I will briefly touch on how these advances could integrate with emerging deep-learning techniques to push the frontiers of quantum many-body continuum calculations (2504.20195).
