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…
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 inv…
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…
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…
Hall-like behaviour of higher rank Chern-Simons theory of fractons
Erica Bertolini, Alberto Blasi, Nicola Maggiore +1
Fracton phases of matter constitute an interesting point of contact between condensed matter and high-energy physics. The limited mobility property of fracton quasiparticles finds…
The theory of symmetric tensor field with boundary: Kac-Moody algebras in linearized gravity
Erica Bertolini, Nicola Maggiore
In this paper we consider four dimensional (4D) linearized gravity (LG) with a planar boundary, where the most general boundary conditions are derived following Symanzik's approach…
Covariant fracton gauge theory with boundary
Erica Bertolini, Nicola Maggiore, Giandomenico Palumbo
In this paper we study the consequences of the introduction of a flat boundary on a 4D covariant rank-2 gauge theory described by a linear combination of linearized gravity and cov…
Gauging fractons and linearized gravity
Erica Bertolini, Alberto Blasi, Andrea Damonte +1
We consider the covariant gauge field theory of fractons, which describe a new type of quasiparticles exhibiting novel and nontrivial properties. In particular, we focus on the fie…
Maxwell theory of fractons
Erica Bertolini, Nicola Maggiore
We show that the main properties of the fracton quasiparticles can be derived from a generalized covariant Maxwell-like action. Starting from a rank-2 symmetric tensor field $A_{μν…
Topological BF description of 2D accelerated chiral edge modes
Erica Bertolini, Filippo Fecit, Nicola Maggiore
We consider the topological abelian BF theory with radial boundary on a generic 3D manifold. Our aim is to study if, where and how the boundary keeps memory of the details of the b…
Notes from the bulk: metric dependence of the edge states of Chern-Simons theory
Erica Bertolini, Giulio Gambuti, Nicola Maggiore
The abelian Chern-Simons theory is considered on a cylindrical spacetime , in a not necessarily flat Lorentzian background. As in the flat bulk case with plana…
Holographic Projection of Electromagnetic Maxwell Theory
Erica Bertolini, Nicola Maggiore
The 4D Maxwell theory with single-sided planar boundary is considered. As a consequence of the presence of the boundary, two broken Ward identities are recovered, which, on-shell,…
