Three-dimensional, boost-invariant formalism for systems of relativistically moving constituents
Adam J. Freese, Anne L. Lashbrook, Gerald A. Miller
The paper develops a three‑dimensional light‑front formalism that provides boost‑invariant wave functions for relativistic systems, introduces the operator for the Miller‑Brodsky v…
Quantum stress and torsion distributions in the deuteron
Wim Cosyn, Adam Freese, Alan Sosa
Stress distributions in the deuteron are related to form factors of the asymmetric energy-momentum tensor through three-dimensional Fourier transforms. There are eleven such form f…
Noether's theorems and the energy-momentum tensor in quantum gauge theories
Adam Freese
Noether's first and second theorems both imply conserved currents that can be identified as an energy-momentum tensor (EMT). The first theorem identifies the EMT as the conserved c…
Reflections on Noether's second theorem and the energy-momentum tensor
Adam Freese
Through symmetry of the action under global spacetime translations, Noether's first theorem infamously entails an energy-momentum tensor (EMT) that is neither symmetric nor gauge-i…
Mechanical form factors and densities of non-relativistic fermions
Adam Freese
The hadron physics community has been actively debating the interpretation of so-called mechanical properties of hadrons. Non-relativistic quantum-mechanical systems like the hydro…
