Holographic Spread Complexity from Branes and Strings
Dimitrios Chatzis, Madison Hammond, Carlos Nunez +2
We study Krylov spread complexity in holographic theories using genuine string-theory probes. Building on the proposal that the growth rate of spread complexity is measured by a pr…
Supersymmetric AdS Solitons, Coulomb Branch Flows and Twisted Compactifications
Dimitrios Chatzis, Madison Hammond, Georgios Itsios +2
This work, which accompanies [1], is about constructing smooth solutions in type II and eleven dimensional supergravity which describe supersymmetry preserving RG flows from four-d…
Universal Observables, SUSY RG-Flows and Holography
Dimitrios Chatzis, Madison Hammond, Georgios Itsios +2
We construct and analyse infinite classes of regular supergravity backgrounds dual to four-dimensional superconformal field theories (SCFTs) compactified on a circle with a supersy…
On the stability of holographic confinement with magnetic fluxes
Ali Fatemiabhari, Carlos Nunez, Maurizio Piai +1
We analyze the stability properties of a simple holographic model for a confining field theory. The gravity dual consists of an Abelian gauge field, with non-trivial magnetic flux,…
Holography for Confined and Deformed Theories: TsT-Generated Solutions in type IIB Supergravity
Federico Castellani, Carlos Nunez
In this paper, we present a series of solutions of type IIB Supergravity, obtained through the TsT deformation of a seed background that is holographically dual to Sup…
SCFT deformations via uplifted solitons
Dimitrios Chatzis, Ali Fatemiabhari, Carlos Nunez +1
A holographic method for implementing a particular supersymmetry-preserving deformation to 4d SCFTs is presented. At the heart of the procedure is a soliton solution of minimal $d=…
