The exact Wheeler-DeWitt equation for the scale-factor minisuperspace model
Eftychios Kaimakkamis, Hervé Partouche, Karunava Sil +1
We consider the classical minisuperspace model describing a closed, homogeneous and isotropic Universe, with a positive cosmological constant. Upon canonical quantization, the infi…
Information Scrambling with Higher-Form Fields
Karunava Sil, Sourav Maji, Stavros Christodoulou +1
The late time behaviour of OTOCs involving generic non-conserved local operators show exponential decay in chaotic many body systems. However, it has been recently observed that fo…
A formalism for the ambiguities of the Wheeler-DeWitt equation
Eftychios Kaimakkamis, Karunava Sil
We study ambiguities in the precise formulation of the Wheeler-DeWitt equation for the wavefunction of the Universe that arise due to different operator orderings in the quantum Ha…
A holographic study of the characteristics of chaos and correlation in the presence of backreaction
Shankhadeep Chakrabortty, Hironori Hoshino, Sanjay Pant +1
In this work, we perform a holographic study to estimate the effect of backreaction on the correlation between two subsystems forming the thermofield double (TFD) state. Each of th…
Quantum information scrambling and quantum chaos in little string theory
Sandip Mahish, Karunava Sil
In the current manuscript we perform a systematic investigation about the effects of nonlocal interaction to the spread of quantum information in many body system. In particular, w…
Supersymmetric Graphene on Squashed Hemisphere
Rajesh Kumar Gupta, Augniva Ray, Karunava Sil
We compute the partition function of supersymmetric mixed dimensional QED on a squashed hemisphere using localization. Mixed dimensional QED is an abelian gauge theo…
Pole skipping and chaos in anisotropic plasma: a holographic study
Karunava Sil
Recently, a direct signature of chaos in many body system has been realized from the energy density retarded Green's function using the phenomenon of `pole skipping'. Moreover, spe…
Effect of back reaction on entanglement and subregion volume complexity in strongly coupled plasma
Shankhadeep Chakrabortty, Sanjay Pant, Karunava Sil
The back reaction imparted by a uniform distribution of heavy static fundamental quarks on large strongly coupled gauge theory can be holographically realized as a deformatio…
A note on size-momentum correspondence and chaos
Sandip Mahish, Shrohan Mohapatra, Karunava Sil +1
The aim of this note is to explore Susskind's proposal [arXiv:1802.01198] on the connection between operator size in chaotic theories and the bulk momentum of a particle falling in…
On Bulk Viscosity at Weak and Strong 't Hooft Couplings
Alina Czajka, Keshav Dasgupta, Charles Gale +4
Bulk viscosity is an important transport coefficient that exists in the hydrodynamical limit only when the underlying theory is non-conformal. One example being thermal QCD with la…
Bulk Viscosity at Extreme Limits: From Kinetic Theory to Strings
Alina Czajka, Keshav Dasgupta, Charles Gale +4
In this paper we study bulk viscosity in a thermal QCD model with large number of colors at two extreme limits: the very weak and the very strong 't Hooft couplings. The weak coupl…

Karunava Sil
Using the UV-complete top-down type IIB holographic dual of large- thermal QCD as constructed in arXiv:hep-th/0902.1540, in arXiv:1507.02692[hep-th], the type IIB background of…
Delocalized SYZ Mirrors and Confronting Top-Down -Structure Holographic Meson Masses at Finite and with P(article) D(ata) G(roup) Values
Vikas Yadav, Aalok Misra, Karunava Sil
Meson spectroscopy at finite gauge coupling - whereat any perturbative QCD computation would break down - and finite number of colors, from a top-down holographic string model, has…

The top-down type IIB holographic dual of large- thermal QCD as constructed in arXiv:0902.1540 involving a fluxed resolved warped deformed conifold, its delocalized type IIA SYZ…
New Insights into Properties of Large-N Holographic Thermal QCD at Finite Gauge Coupling at (the Non-Conformal/Next-to) Leading Order in N
Karunava Sil, Aalok Misra
In the context of [1]'s string theoretic dual of large-N thermal QCD-like theories at finite gauge/string coupling (as part of the `MQGP' limit of [2]), we discuss the following. F…
On Aspects of Holographic Thermal QCD at Finite Coupling
Karunava Sil, Aalok Misra
Some Physics (obtaining lattice-compatible deconfinement temperature, some transport coefficients and Einstein's relation) and Mathematics (torsion classes and supersymmetry) issue…
