Holographic Krylov spread complexity for a confining multi-charge AdS soliton
Dimitrios Chatzis, Madison Hammond, Ricardo T. Santamaria +1
We study holographic spread complexity for a Type IIB solution dual to a deformation of SYM that flows to a confining (2+1)-dimensional supersymmetric theory in t…
Holographic Spread Complexity at Fixed Charge: Routhians, Branes and Strings
Dimitrios Chatzis, Madison Hammond, Carlos Nunez +2
Holographic spread (Krylov) complexity relates the growth of a boundary state's complexity to the proper radial momentum of a probe falling into the bulk. Unitary evolution makes s…
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…
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…
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…
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=…
Conformal to confining SQFTs from holography
Dimitrios Chatzis, Ali Fatemiabhari, Carlos Nunez +1
In this paper we present three new families of smooth Type II string theory backgrounds. These are dual to supersymmetry-preserving deformations of 4d SCFTs. The deformations inclu…
Stability of Wilson Loops and Other Observables in Various Type IIB Backgrounds
Dimitrios Chatzis
This work involves the stability study of various observables (Wilson loop, 't Hooft loop and Entanglement Entropy) under linear fluctuations of the coordinates for certain ten-dim…
