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…
From Diamond Gaugings to Dualisations
Dimitrios Chatzis, John M. Marley, Daniel C. Thompson
We revisit the proposal that coupling two six-dimensional holomorphic Chern-Simons theories generates gaugings throughout the twistor-space diamond relating 6d hCS, 4d self-dual Ya…
Holographic Entanglement Entropy in Quiver Theories
Dimitrios Chatzis, Ali Fatemiabhari, Mauro Giliberti +1
This work presents a study of the entanglement entropy (EE) in a class of four-dimensional linear quiver SCFTs deformed by the presence of a VEV. We review the hologra…
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…
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=…
