The quadratic growth of Krylov spread complexity in the BTZ black hole

Aranya Bhattacharya, Mario Flory, Michal P. Heller +2

The boundary quantity that captures the growth of black-hole interiors quantified by holographic complexity remains unknown beyond 2d dilaton gravity. We provide a critical analysi…

On the role of Area Metrics in AdS/CFT

Aranya Bhattacharya, Lavish Chawla, Mario Flory +1

We explore the potential role of area metrics, a generalised notion of geometry, in the AdS/CFT correspondence. Guided by the Ryu-Takayanagi formula and the first law of entangleme…

Holographic complexity of Jackiw-Teitelboim gravity from Karch-Randall braneworld

Aranya Bhattacharya, Arpan Bhattacharyya, Ayan K. Patra

Recently, it has been argued in [1] that Jackiw-Teitelboim (JT) gravity can be naturally realized in the Karch-Randall braneworld in dimensions. Using the `complexity=volum…

Pseudo complexity of purification for free scalar field theories

Aranya Bhattacharya, Arpan Bhattacharyya, Sabyasachi Maulik

We compute the pseudo complexity of purification corresponding to the reduced transition matrices for free scalar field theories with an arbitrary dynamical exponent. We plot the b…

Bath deformations, islands and holographic complexity

Aranya Bhattacharya, Arpan Bhattacharyya, Pratik Nandy +1

Considering a doubly holographic model, we study the evolution of holographic subregion complexity corresponding to deformations of bath state by a relevant scalar operator, which…

Partial islands and subregion complexity in geometric secret-sharing model

Aranya Bhattacharya, Arpan Bhattacharyya, Pratik Nandy +1

We compute the holographic subregion complexity of a radiation subsystem in a geometric secret-sharing model of Hawking radiation in the "complexity = volume" proposal. The model i…

Islands and complexity of eternal black hole and radiation subsystems for a doubly holographic model

Aranya Bhattacharya, Arpan Bhattacharyya, Pratik Nandy +1

We study the entanglement islands and subsystem volume complexity corresponding to the left/ right entanglement of a conformal defect in -dimensions in Randall-Sundrum (RS) bran…

Topological shadows and complexity of islands in multiboundary wormholes

Aranya Bhattacharya, Anindya Chanda, Sabyasachi Maulik +2

Recently, remarkable progress in recovering the Page curve of an evaporating black hole (BH) in Jackiw-Teitelboim gravity has been achieved through use of Quantum Extremal surfaces…

HEE and HSC for flavors: perturbative structure in open string geometries

Avik Banerjee, Aranya Bhattacharya, Sabyasachi Maulik

Introduction of electric field in the D-brane worldvolume induces a horizon in the open string geometry perceived by the brane fluctuations. We study the holographic entanglement e…

Multipartite Purification, Multiboundary Wormholes and Islands in AdS/CFT

Aranya Bhattacharya

The holographic duals of Entanglement of Purification through the Entanglement Wedge Cross Section has been a well-discussed topic in the literature recently. More general entangle…

Entanglement Entropy and Subregion Complexity in Thermal Perturbations around Pure-AdS Spacetime

Aranya Bhattacharya, Kevin T. Grosvenor, Shibaji Roy

We compute the holographic entanglement entropy and subregion complexity of spherical boundary subregions in the uncharged and charged AdS black hole backgrounds, with the \textbf{…

Holographic Entanglement Entropy, Subregion Complexity and Fisher Information metric of `black' Non-SUSY D3 Brane

Aranya Bhattacharya, Shibaji Roy

The BPS D3 brane has a non-supersymmetric cousin, called the non-susy D3 brane, which is also a solution of type IIB string theory. The corresponding counterpart of black D3 brane…

Holographic entanglement entropy and entanglement thermodynamics of `black' non-susy D3 brane

Aranya Bhattacharya, Shibaji Roy

Like BPS D3 brane, the non-supersymmetric (non-susy) D3 brane of type IIB string theory is also known to have a decoupling limit and leads to a non-supersymmetric AdS/CFT correspon…
