Surface transport in plasma-balls
Jay Armas, Jyotirmoy Bhattacharya, Nilay Kundu
We study the surface transport properties of stationary localized configurations of relativistic fluids to the first two non-trivial orders in a derivative expansion. By demanding…
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…
Multi-spike strings in with mixed three-form fluxes
Aritra Banerjee, Abhishake Sadhukhan
The string sigma model in supported by mixed three-form fluxes has recently been proved to be integrable which led to a plethora of work in this background includ…
Covariant Action for Type IIB Supergravity
Ashoke Sen
Taking clues from the recent construction of the covariant action for type II and heterotic string field theories, we construct a manifestly Lorentz covariant action for type IIB s…
Poisson equation for the Mercedes diagram in string theory at genus one
Anirban Basu
The Mercedes diagram has four trivalent vertices which are connected by six links such that they form the edges of a tetrahedron. This three loop Feynman diagram contributes to the…
Do All BPS Black Hole Microstates Carry Zero Angular Momentum?
Abhishek Chowdhury, Richard S. Garavuso, Swapnamay Mondal +1
From the analysis of the near horizon geometry and supersymmetry algebra it has been argued that all the microstates of single centered BPS black holes with four unbroken supersymm…
