[Theory-seminars] Cake seminar Wednesday, January 7 - Adam Freese

[Adam Freese]

Greetings everyone,

Happy new year! We'll be starting off the Cake Seminar series for 2026 with a seminar by Adam Freese from the Center for Nuclear Femtography. The seminar will take place in-person on January 7, 2026 at 1:00 PM EST in CC F224-225, and will also be broadcast on Zoom:

Please find the title and abstract below.

Title:
Stresses in the Deuteron

Abstract:
The deuteron, as a spin-one hadron, has a rich, asymmetric energy-momentum tensor (EMT) parametrized by 11 form factors. The proton and neutron contributions to these form factors are calculated using old-fashioned non-relativistic quantum mechanics, and Fourier transforms are taken to obtain spatial distributions of various mechanical properties including mass, momentum, and stresses. The stresses include familiar pressures and shear stresses, but also a new torsion stress that arises in spin-one hadrons and is responsible for reorienting fermion spins. The Cauchy momentum equation is used to obtain force distributions in the bound nucleons, which are non-radial owing to the presence of the tensor force and spin-orbit coupling.

We look forward to seeing you there!

Kind regards,
Adam
(on behalf of the organizing committee: Adam, Joe and Pia)
