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…
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 observables in TsT deformations of confining theories
Madison Hammond, Georgios Itsios
We construct new families of type-IIB supergravity solutions by employing TsT transformations on the ten-dimensional geometry that arises after the uplift of the five-dimensional s…
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…
