On Boundaries, Charges and Fermi Fields
Published 13 Feb 2020 in hep-th, gr-qc, hep-ph, math-ph, and math.MP | (2002.05372v1)
Abstract: We address some general issues related to torsion and Noether currents for Fermi fields in the presence of boundaries, with emphasis on the conditions that guarantee charge conservation. We also describe exact solutions of these boundary conditions and some implications for string vacua with broken supersymmetry.
