6. Nuclear lattice simulations for ab initio nuclear structure

Prof. Dean Lee (Michigan State University)

11/08/2025, 13:30

This talk covers recent algorithmic developments for nuclear lattice simulations and calculations of ab initio nuclear structure. I discuss wavefunction matching, the pinhole algorithm, parametric matrix models, and calculations of the beryllium, carbon, and silicon isotopes. I also present theoretical and experimental evidence for multimodal superfluidity of neutrons.

7. How high-precision measurements can impact halo physics

Dr Kevin Fossez (Florida State University & FRIB)

Halo structures are sensitive threshold phenomena, characterized by weak binding, a large spatial extension, and the emergence of new effective degrees of freedom. As such, they can provide stringent constraints on nuclear forces. In this talk, I will discuss the physics of halo states and explain how high-precision measurements of energies and radii can advance our understanding of nuclear...

8. Developing precise predictions of electroweak structure of nuclei

Matthias Heinz (Oak Ridge National Laboratory)

This contribution will highlight recent work on ab initio theory predictions of electroweak properties of nuclei. Ab initio calculations are predictive, yet still relatively uncertain when compared to precision measurements. Still such calculations can both guide the interpretation of experimental signals and be calibrated with experimental data to provide more precise predictions.

I will...

16. Chiral N3LO_Texas: Towards more accurate nuclear interactions

Dr Baishan Hu (Texas A&M University)

12/08/2025, 11:00

Over the past decades, ab initio nuclear theory has made dramatic progress, reaching even heavy nuclei such as 208Pb. Yet, the nature of nuclear forces remains a profound mystery. In this talk, I will first give a brief overview of some of the most commonly used nuclear forces derived from chiral EFT. I will then introduce a new chiral N3LO_Texas two- and three-body interaction, capable of...
