We are proud to announce that Pieter Maris has been elected a Fellow of the American Physical Society (APS) “for pioneering work in fundamental theory spanning hadronic physics, as described by quantum chromodynamics and ab initio nuclear structure using the chiral effective field theory of inter-nucleon interactions”.
Pieter’s work spans hadronic physics quantum chromodynamics (QCD) and ab initio nuclear structure studies using chiral effective field theory (EFT) of inter-nucleon interactions.
Two of Pieter’s most impactful achievements underpin this honor:
- Covariant Bethe-Salpeter Framework for Mesons: Maris co-developed a fully covariant Bethe-Salpeter approach to meson structure grounded in QCD, incorporating chiral and vector current symmetries. This work introduced a widely adopted dynamical confinement mechanism and remains a cornerstone in hadronic physics (P. Maris and P. Tandy, Phys. Rev. C 60, 055214 (1999); [593 citations]).
- Ab Initio Nuclear Structure with Chiral EFT: As part of the LENPIC collaboration, Maris helped establish a robust theoretical framework for light nuclei using the No-Core Shell Model with chiral EFT interactions complete through N2LO. This approach, rooted in QCD, has become essential for interpreting results from FRIB and other facilities (P. Maris et al., Phys. Rev. C 103, 054001 (2021) – Editor’s Suggestion; [95 citations]).
Pieter’s work continues to shape the theoretical landscape of nuclear physics, bridging fundamental theory with experimental programs at JLAB, FRIB, and beyond. His selection as an APS Fellow is a testament to the depth and impact of his contributions to the field.
