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…
