TITLE
Understanding Fermionic Generalized Symmetries
ABSTRACT
We explore new aspects of internal fermionic shifting symmetries present in physical systems such as free Dirac spinors and p-form tensor-spinor fields. We propose a novel procedure to gauge these global symmetries which also introduces a new Stückelberg mechanism to give a mass to free fermionic fields. Furthermore we find new magnetic fermionic symmetries in these physical systems whose charged objects are disorder operators. For the case of a Dirac spinor we discuss a dual description where the magnetic symmetry acts on the holonomies of a dual 2-form tensor-spinor. Further generalizations such as higher-group-like structures are also discussed.
