Asymptotic dynamics of three dimensional supergravity and higher spin gravity revisited
Wout Merbis, Turmoli Neogi, Arash Ranjbar
We reconsider the Hamiltonian reduction of the action for three dimensional AdS supergravity and higher spin AdS gravity in the Chern-Simons formulation under asymptotically…
Memory effects from holonomies
Ali Seraj, Turmoli Neogi
We provide a uniform treatment of electromagnetic and gravitational memory effects, based on the gravito-electromagnetic formulation of GR and a generalization of the geodesic devi…
Dual Theory for maximally extended flat Supergravity
Nabamita Banerjee, Arindam Bhattacharjee, Surajit Biswas +1
Maximally extended dimensional flat Supergravity theories exist for a class of super-Poincaré algebras for arbitrary . They have rich asymptotic st…
Local supersymmetry and the square roots of Bondi-Metzner-Sachs supertranslations
Oscar Fuentealba, Marc Henneaux, Sucheta Majumdar +2
Super-BMS algebras -- also called BMS superalgebras -- are graded extensions of the BMS algebra. They can be of two different types: they can contain either a finite nu…
Asymptotic structure of the Rarita-Schwinger theory in four spacetime dimensions at spatial infinity
Oscar Fuentealba, Marc Henneaux, Sucheta Majumdar +2
We investigate the asymptotic structure of the free Rarita-Schwinger theory in four spacetime dimensions at spatial infinity in the Hamiltonian formalism. We impose boundary condit…
Asymptotic realization of the super-BMS algebra at spatial infinity
Marc Henneaux, Javier Matulich, Turmoli Neogi
Explicit boundary conditions are given at spatial infinity for four-dimensional supergravity, which provide a realization of the super-BMS algebra of Awada, Gibbons and Shaw. The r…
New N=2 SuperBMS algebra and Invariant Dual Theory for 3D Supergravity
Nabamita Banerjee, Arindam Bhattacharjee, Neetu +1
We have constructed a two dimensional theory dual to 3D asymptotically flat Supergravity in presence of two supercharges with(out) internal symmetry. The duals in both the case…
Maximally -extended super-BMS algebras and Generalized 3D Gravity Solutions
Nabamita Banerjee, Arindam Bhattacharjee, Ivano Lodato +1
We consider the maximal extended supergravity theory in 3 dimensions with fermionic generators transforming under real but non necessarily irreducible representations of…
Dual Superconformal Symmetry of Chern-Simons theory with Fundamental Matter at Large
Karthik Inbasekar, Sachin Jain, Sucheta Majumdar +5
Dual conformal symmetry and Yangian symmetry are symmetries of amplitudes that have aided the study of scattering amplitudes in highly supersymmetric theories like SYM…
N=4 Supersymmetric BMS3 algebras from asymptotic symmetry analysis
Nabamita Banerjee, Ivano Lodato, Turmoli Neogi
We consider three dimensional flat supergravity, with an abelian R-symmetry enhancing the gravitational phase space. We obtain the field configuration whose asymptotic symmet…
Extended Supersymmetric BMS algebras and Their Free Field Realisations
Nabamita Banerjee, Dileep P. Jatkar, Ivano Lodato +2
We study supersymmetric extensions of the three dimensional BMS algebra (BMS) with most generic possible central extensions. We find that -extended supersymmetri…
Free-field realisations of the BMS algebra and its extensions
Nabamita Banerjee, Dileep P. Jatkar, Sunil Mukhi +1
We construct an explicit realisation of the BMS algebra with nonzero central charges using holomorphic free fields. This can be extended by the addition of chiral matter to a r…
