Edge modes in Chern-Simons theory on a strip
Erica Bertolini, Michael Doyle, Nicola Maggiore +2
We investigate abelian Chern-Simons gauge theory on a strip geometry with two spatial boundaries. In the presence of boundaries, gauge invariance is broken by boundary conditions,…
Covariant field theory of 3D massive fractons
Erica Bertolini, Matteo Carrega, Nicola Maggiore +1
We construct a covariant and gauge-invariant theory describing massive fractons in three spacetime dimensions, based on a symmetric rank-2 tensor field. The model includes a Chern-…
Quasi-topological mass generation for 3D linearized gravity
Erica Bertolini, Edoardo Lui, Nicola Maggiore
We present a new mass generation mechanism for linearized gravity in three spacetime dimensions, which consists of a lower-dimensional Chern-Simons-like term added to the invariant…
Fractonic self-duality and covariant magnetic fractons
Erica Bertolini, Giandomenico Palumbo
Fractons, excitations with restricted mobility, have emerged as a novel paradigm in high-energy and condensed matter physics, revealing deep connections to gauge theories and gravi…
Fractons from covariant higher-rank 3D BF theory
Erica Bertolini, Alberto Blasi, Matteo Carrega +2
In this paper we study the 3D gauge theory of two tensor gauge fields: , which we take symmetric, and , with no symmetry on its indices. The corresponding…
Quasi-topological fractons: a 3D dipolar gauge theory
Erica Bertolini, Alberto Blasi, Nicola Maggiore
We consider the theory of a generic rank-2 tensor field in three spacetime dimensions, which involves a symmetric tensor field transforming under infinitesimal diffeomorphisms, and…
