Higher-Order Newton-Cartan Gravity
Biel Cardona, Luca Romano
We study the non-relativistic Newton-Cartan limit of higher-order gravity theories in arbitrary dimensions. We first study it at the level of the action by introducing an additiona…
Entanglement Renormalization of a -deformed CFT
Biel Cardona, Javier Molina-Vilaplana
In this work we use cMERA, a continuous tensor network, to find a Gaussian approximation to the ground state of a -deformed scalar CFT on the line, to first order in the…
Critical lumpy black holes in AdS
Biel Cardona, Pau Figueras
In this paper we study lumpy black holes with AdS asymptotics, where the isometry group coming from the sphere factor is broken down to SO(). Depending on the v…
Critical Kaluza-Klein black holes and black strings in D = 10
Biel Cardona, Pau Figueras
We construct static vacuum localized black holes and non-uniform black strings in ten spacetime dimensions, where one of the dimension is compactified on circle. We study the phase…
Dynamics of Carroll Strings
Biel Cardona, Joaquim Gomis, Josep M Pons
We construct the canonical action of a Carroll string doing the Carroll limit of a canonical relativistic string. We also study the Killing symmetries of the Carroll string, which…
