BMS algebra as an extension of the Poincaré symmetry in light-cone gravity

Sudarshan Ananth, Lars Brink, Sucheta Majumdar

We analyze possible local extensions of the Poincaré symmetry in light-cone gravity in four dimensions. We use a formalism where we represent the algebra on the two physical degree…

Islands for Entanglement Negativity

Jaydeep Kumar Basak, Debarshi Basu, Vinay Malvimat +2

We advance two alternative proposals for the island contributions to the entanglement negativity of various pure and mixed state configurations in quantum field theories coupled to…

Universal Correlators and Novel Cosets in 2d RCFT

Sunil Mukhi, Rahul Poddar

The two-character level-1 WZW models corresponding to Lie algebras in the Cvitanović-Deligne series have been argued to form coset pairs with respect…

Asymptotic Symmetry and Classical holographic dual of supergravity

Arindam Bhattacharjee

We consider minimal supergravity on (2+1)dimensional de-Sitter background. We fix the fall-off conditions for gravitini fields in order to fix the asymptotic phase space. Using the…

Constraining momentum space correlators using slightly broken higher spin symmetry

Sachin Jain, Renjan Rajan John, Vinay Malvimat

In this work, building up on [1] we present momentum space Ward identities related to broken higher spin symmetry as an alternate approach to computing correlators of spinning oper…

Classical Soft Theorem in the AdS-Schwarzschild spacetime in small cosmological constant limit

Nabamita Banerjee, Arindam Bhattacharjee, Arpita Mitra

We have studied scattering of a probe particle by a four dimensional AdS-Schwarzschild black hole at large impact factor. Our analysis is consistent perturbatively to leading order…

Supersymmetric Yang-Mills theory in D=6 without anti-commuting variables

Sudarshan Ananth, Hannes Malcha, Chetan Pandey +1

Supersymmetric Yang-Mills theory is formulated in six dimensions, without the use of anti-commuting variables. This is achieved using a new Nicolai map, to third order in the coupl…

New Asymptotic Conservation laws for Electromagnetism

Sayali Atul Bhatkar

We obtain the subleading tail to the memory term in the late time electromagnetic radiative field generated due to a generic scattering of charged bodies. We show that there exists…

Higher spins, quadratic forms and amplitudes

Sudarshan Ananth, Chetan Pandey, Saurabh Pant

The light-cone Hamiltonians for spin 1 and spin 2 fields, describing both the pure and the maximally supersymmetric theories, may be expressed as quadratic forms. In this paper, we…

Generalized BMS Algebra at Timelike Infinity

Anupam A H, Aniket Khairnar, Arpan Kundu

BMS group (and it's various generalizations) at null infinity have been studied extensively in the literature as the symmetry group of asymptotically flat spacetimes. The intricate…

Perturbative linearization of supersymmetric Yang-Mills theory

Sudarshan Ananth, Olaf Lechtenfeld, Hannes Malcha +3

Supersymmetric gauge theories are characterized by the existence of a transformation of the bosonic fields (Nicolai map) such that the Jacobi determinant of the transformation equa…

Momentum space spinning correlators and higher spin equations in three dimensions

Sachin Jain, Renjan Rajan John, Vinay Malvimat

In this article, we explicitly compute in momentum space the three and four-point correlation functions involving scalar and spinning operators in the free bosonic and the free fer…

Classification of all 3 particle S-matrices quadratic in photons or gravitons

Soumangsu Chakraborty, Subham Dutta Chowdhury, Tushar Gopalka +3

We explicitly construct every kinematically allowed three particle graviton-graviton- and photon-photon- S-matrix in every dimension and for every choice of the little group…

Rational CFT With Three Characters: The Quasi-Character Approach

Sunil Mukhi, Rahul Poddar, Palash Singh

Quasi-characters are vector-valued modular functions having an integral, but not necessarily positive, q-expansion. Using modular differential equations, a complete classification…

Supersymmetric Yang-Mills Theories: not quite the usual perspective

Sudarshan Ananth, Hermann Nicolai, Chetan Pandey +1

In this paper, we take up an old thread of development concerning the characterization of supersymmetric theories without any use of anticommuting variables that goes back to one o…
