Edge physics and the Casimir interaction in Maxwell-Chern-Simons theory on a strip

Nicola Maggiore

We study how boundaries affect Maxwell-Chern-Simons theory, a three-dimensional gauge theory that combines ordinary electromagnetic propagation with a topological Chern-Simons term…

Covariant Fracton Electrodynamics in Six Dimensions

Nicola Maggiore

We formulate a covariant version of Maxwell-like fracton electrodynamics in six dimensions using a symmetric tensor gauge field with scalar gauge symmetry $δA_{μν}=\partial_μ\parti…

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,…

On the Wilson-Fisher fixed point in the limit of integer spacetime dimensions

Bernardo Zan

The Wilson-Fisher fixed point defines a continuous family of interacting conformal field theories in non-integer dimensions. In integer dimensions, it is widely believed to lie in…

Quantized Dirac Fields in torsionful gravity: cosmological implications and links with the dark universe

Antonio Capolupo, Sante Carloni, Luca Fabbri +3

We consider a classical field in square torsion theory as a source of torsion for a quantum fermion field in FLRW metric. In the framework of QFT, we obtain vacuum contributions to…

Phases of 2d Gauge Theories and Symmetric Mass Generation

Rishi Mouland, David Tong, Bernardo Zan

We study the dynamics and phase structure of Abelian gauge theories in dimensions. These include gauge theory coupled to a scalar and a fermion, as well as the two-f…

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…

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…

Entropy-area law and temperature of de Sitter horizons from modular theory

Edoardo D'Angelo, Markus B. Fröb, Stefano Galanda +3

We derive an entropy-area law for the future horizon of an observer in diamonds inside the static patch of de Sitter spacetime, taking into account the backreaction of quantum matt…

Superconformal anomalies from superconformal Chern-Simons polynomials

Camillo Imbimbo, Davide Rovere, Alison Warman

We consider the 4-dimensional Lie superconformal algebra and search for completely "symmetric" (in the graded sense) 3-index invariant tensors. The solution we find…

Relaxation terms for anomalous hydrodynamic transport in Weyl semimetals from kinetic theory

Andrea Amoretti, Daniel K. Brattan, Luca Martinoia +2

We consider as a model of Weyl semimetal thermoelectric transport a -dimensional charged, relativistic and relaxed fluid with a chiral anomaly. We…

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…

Restoring time-reversal covariance in relaxed hydrodynamics

Andrea Amoretti, Daniel K. Brattan, Luca Martinoia +1

In hydrodynamics, for generic relaxations, the stress tensor and charge current two-point functions are not time-reversal covariant. This remains true even if the Martin-Kad…

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…

Gibbons-Hawking-York boundary terms and the generalized geometrical trinity of gravity

Johanna Erdmenger, Bastian Heß, Ioannis Matthaiakakis +1

General relativity (GR) as described in terms of curvature by the Einstein-Hilbert action is dynamically equivalent to theories of gravity formulated in terms of spacetime torsion…

Leading order magnetic field dependence of conductivities in anomalous hydrodynamics

Andrea Amoretti, Daniel K. Brattan, Luca Martinoia +1

We show that literature results claimed for the magnetic field dependence of the longitudinal conductivity in anomalous first-order hydrodynamics are frame dependent at this deriva…

Non-dissipative electrically driven fluids

Andrea Amoretti, Daniel K. Brattan, Luca Martinoia +1

Existing hydrodynamic models of charged fluids consider any external electric field acting on the fluid as either first order in the hydrodynamic derivative expansion and completel…
