Supergravity flows, wormholes and their pseudo-Hermitian holographic duals
Jose M. Begines, Antón F. Faedo, Carlos Hoyos +1
We find solutions to consistent truncations of supergravity where some real scalars are analytically extended to imaginary values, ensuring the metric remains real-valued. Among th…

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…
