First Order Galilean Superfluid Dynamics
Nabamita Banerjee, Suvankar Dutta, Akash Jain
We study dynamics of (anomalous) Galilean superfluid up to first order in derivative expansion, both in parity-even and parity-odd sectors. We construct a relativistic system -- nu…
Super-BMS algebras from flat supergravities
Ivano Lodato, Wout Merbis
We consider two possible flat space limits of three dimensional AdS supergravity. They differ by how the supercharges are scaled with the AdS radius : t…
Flat Holography: Aspects of the dual field theory
Arjun Bagchi, Rudranil Basu, Ashish Kakkar +1
Assuming the existence of a field theory in D dimensions dual to (D+1)-dimensional flat space, governed by the asymptotic symmetries of flat space, we make some preliminary remarks…
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…
The large D black hole Membrane Paradigm at first subleading order
Yogesh Dandekar, Anandita De, Subhajit Mazumdar +2
In the large D limit, and under certain circumstances, it has recently been demonstrated that black hole dynamics in asymptotically flat spacetime reduces to the dynamics of a non…
Tensionless Superstrings: View from the Worldsheet
Arjun Bagchi, Shankhadeep Chakrabortty, Pulastya Parekh
In this brief note, we show that the residual symmetries that arise in the analysis of the tensionless superstrings in the equivalent of the conformal gauge is (a trivial extension…
Non-spherically symmetric black string perturbations in the large D limit
Amruta Sadhu, Vardarajan Suneeta
We consider non-spherically symmetric perturbations of the uncharged black string/flat black brane in the large dimension (D) limit of general relativity. We express the perturbati…
Two-dimensional RCFT's without Kac-Moody symmetry
Harsha R. Hampapura, Sunil Mukhi
Using the method of modular-invariant differential equations, we classify a family of Rational Conformal Field Theories with two and three characters having no Kac-Moody algebra. I…
Higher derivative corrections to BPS black hole attractors in 4d gauged supergravity
Kiril Hristov, Stefanos Katmadas, Ivano Lodato
We analyze BPS black hole attractors in 4d gauged supergravity in the presence of higher derivative supersymmetric terms, including a Weyl-squared-type action, and determine the re…
Deriving field theories for particles of arbitrary spin with and without supersymmetry
Sudarshan Ananth
We review the derivation of light-cone interaction vertices for fermionic and bosonic fields of arbitrary spin. The resulting amplitudes and their factorization properties are disc…
The Resolution of an Entropy Puzzle for 4D non-BPS Black Holes
Nabamita Banerjee, Sukruti Bansal, Ivano Lodato
We show the equality between macroscopic and microscopic black hole entropy for a class of four dimensional non-supersymmetric black holes in supergravity theory, up t…
Cosets of Meromorphic CFTs and Modular Differential Equations
Matthias R. Gaberdiel, Harsha R. Hampapura, Sunil Mukhi
Some relations between families of two-character CFTs are explained using a slightly generalised coset construction, and the underlying theories (whose existence was only conjectur…
The off-shell c-map
Nabamita Banerjee, Bernard de Wit, Stefanos Katmadas
The off-shell version of the c-map is presented, based on a systematic off-shell reduction from four to three space-time dimensions for supergravity theories with eight supercharge…
Exceptional versus superPoincaré algebra as the defining symmetry of maximal supergravity
Sudarshan Ananth, Lars Brink, Sucheta Majumdar
We describe how one may use either the superPoincaré algebra or the exceptional algebra to construct maximal supergravity theories in the light-cone formalism. The d=4 construction…
