Emergent fracton strings from covariant bi-form gauge field theory
Erica Bertolini, Hyungrok Kim, Giandomenico Palumbo
We present a covariant field-theoretical framework for a rank-4 tensor gauge field theory describing fractonic string-like objects. We show that the most general quadratic, parity-…
Strings as Hyper-Fractons
Erica Bertolini, Hyungrok Kim
We systematically examine all possible Gauss laws obeying spatial rotation symmetry, characterising the corresponding conserved charges. In the case of conserved higher moments, th…
Notes from the bulk
Erica Bertolini
The scope of this Ph.D thesis is to study the effects of the presence of a boundary from a Quantum Field Theoretical perspective, searching for new physics and explanations of obse…
Covariant Interacting Fractons
Erica Bertolini, Hyungrok Kim
We show that there exists a natural analogue of the Yang-Mills equations using the Frölicher-Nijenhuis bracket between vector-valued differential forms. The gauge field is a rank-…
