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…
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…
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…
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…
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…
