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…
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…
Spinodal slowing down and scaling in a holographic model
Alessio Caddeo, Oscar Henriksson, Carlos Hoyos +1
The dynamics of first-order phase transitions in strongly coupled systems are relevant in a variety of systems, from heavy ion collisions to the early universe. Holographic theorie…
