Entanglement transitions in holographic conformal interfaces
Evangelos Afxonidis, Rotem Berman, Ignacio Carreño Bolla +3
We study entanglement transitions for pairs of disjoint intervals in two-dimensional holographic interface conformal field theories. We consider several holographic models with equ…
Defect entanglement entropy for superconformal RG Interfaces
Evangelos Afxonidis, Christopher Rosen
We study the defect contribution to the entanglement entropy of a spherical region centred on four-dimensional superconformal RG interfaces. These interfaces are supersymmetric cod…
Scale without conformal symmetry in hydrodynamics
Evangelos Afxonidis, Jewel Kumar Ghosh, Daniele Musso +2
Scale without conformal symmetry corresponds to an inhomogeneous conservation equation for the virial current sourced by the trace of the energy-momentum tensor. Fluids that are ju…
Connecting boundary entropy and effective central charge at holographic interfaces
Evangelos Afxonidis, Ignacio Carreño Bolla, Carlos Hoyos +1
The entanglement entropy of intervals in interface CFTs is modified in two ways compared to a CFT without interface: there is a finite boundary entropy contribution, and, for…
Fracton Gauge Theories in Curved Spacetimes
Evangelos Afxonidis, Alessio Caddeo, Carlos Hoyos +1
Fractonic matter with dipole symmetry can be coupled to a two-index symmetric tensor gauge field. In this work, we show that this symmetric tensor field, along with other related g…
The boundary entropy function for interface conformal field theories
Evangelos Afxonidis, Andreas Karch, Chitraang Murdia
{In 1+1 dimensional conformal field theory with a boundary the boundary contribution to the entanglement entropy is determined by a single number effectively counting the bound…
On the stability of fracton gravity
Evangelos Afxonidis, Alessio Caddeo, Carlos Hoyos +1
We study the stability of fracton gravity, a variant of linearized gravity where the gauge symmetry is restricted to longitudinal diffeomorphisms. These transformations can be conn…
Fracton gravity from spacetime dipole symmetry
Evangelos Afxonidis, Alessio Caddeo, Carlos Hoyos +1
Dipole charge conservation forces isolated charges to be immobile fractons. These couple naturally to spatial two-index symmetric tensor gauge fields that resemble a spatial metric…
Dipole symmetry breaking and fractonic Nambu-Goldstone mode
Evangelos Afxonidis, Alessio Caddeo, Carlos Hoyos +1
We introduce a family of quantum field theories for fields carrying monopole and dipole charges. In contrast to previous realizations, fields have quadratic two-derivative kinetic…
