Holographic symmetry algebra for the MHV sector revisited
Shamik Banerjee, Mousumi Maitra, Raju Mandal +1
We revisit the holographic symmetry algebra in the MHV sector. We find an infinite dimensional Abelian symmetry algebra whose generators are the conformally soft negative helicity…
Towards an IR finite S-matrix in the flat limit of AdS/CFT
Sarthak Duary, Eliot Hijano, Milan Patra
Asymptotic Fock spaces lead to IR divergences in S-matrices. The issue can be traced back to the assumption of asymptotic decoupling, and its relaxation leads to Faddeev-Kulish sta…
Dressing bulk spinor fields in AdS
Gilad Lifschytz, Milan Patra
We continue the program of bulk reconstruction for fermionic fields. We reconstruct, from the CFT, the Dirac fermion field in coupled to a Chern-Simon gauge field. We sho…
Entropy Current and Fluid-Gravity Duality in Gauss-Bonnet theory
Chandranathan A, Sayantani Bhattacharyya, Milan Patra +1
Working within the approximation of small amplitude expansion, recently an entropy current has been constructed on the horizons of dynamical black hole solution in any higher deriv…
Reparametrization Symmetry of Local Entropy Production on a Dynamical Horizon
Sayantani Bhattacharyya, Pooja Jethwani, Milan Patra +1
Recently, it has been shown that for a dynamical black hole in any higher derivative theory of gravity, one could construct a spatial entropy current, characterizing the in/outflow…
An entropy current and the second law in higher derivative theories of gravity
Sayantani Bhattacharyya, Prateksh Dhivakar, Anirban Dinda +3
We construct a proof of the second law of thermodynamics in an arbitrary diffeomorphism invariant theory of gravity working within the approximation of linearized dynamical fluctua…
Comparison between fluid-gravity and membrane-gravity dualities for Einstein-Maxwell system
Milan Patra
Derivative expansion and large- expansion are two perturbation techniques, which are used to generate dynamical black-brane solutions to Einstein's equations in presence of nega…
Fluid-gravity and membrane-gravity dualities - Comparison at subleading orders
Sayantani Bhattacharyya, Parthajit Biswas, Anirban Dinda +1
In this note we have compared two different perturbation techniques that could be used to generate solutions of Einstein's equations in presence of negative cosmological constant.…
A leading-order comparison between fluid-gravity and membrane-gravity dualities
Sayantani Bhattacharyya, Parthajit Biswas, Milan Patra
In this note, we have compared two different perturbation techniques that are used to generate dynamical black-brane solutions to Einstein equation in presence of negative cosmolog…
