Phases of Euclidean wormholes in JT gravity
Hemant Rathi, Dibakar Roychowdhury
We present a JT gravity set up that reveals the evidence of (Euclidean) wormhole to black hole phase transition at finite charge density and/or chemical potential. We identify the…
Matrix models and non-Abelian T dual of
Dibakar Roychowdhury
We compute Euclidean Wilson loops for BMN Plane Wave Matrix Models. The stringy counterpart of these Wilson loops corresponds to various semi-classical open string embedding that p…
Holographic JT gravity with quartic couplings
Hemant Rathi, Dibakar Roychowdhury
We construct the most general theory of 2D Einstein-dilaton gravity coupled with gauge fields that contains all the 2-derivative and the 4-derivative interactions allowed by…
Analytic (non)integrability of Arutyunov-Bassi-Lacroix model
Jitendra Pal, Arnab Mukherjee, Arindam Lala +1
We use the notion of the gauge/string duality and discuss the Liouvillian (non) integrability criteria for string sigma models in the context of recently proposed Arutyunov-Bassi-L…
Non-integrability for SCFTs in
Dibakar Roychowdhury
We explore the \emph{Liouvillian} non-integrability criteria for long quiver gauge theories those preserve SUSY in . We probe type IIB solutions with (an $…
Fragmentation and defragmentation of strings in type IIA and their holographic duals
Dibakar Roychowdhury
We probe type IIA geometries with \emph{folded} semiclassical strings those encode the strong coupling dynamics associated with long operators in a class of SCFTs pertaining to spa…
