Doubly-scaled planar SYM & Carroll Holography
Arjun Bagchi, Prateksh Dhivakar, Alok Laddha +1
In their seminal paper, Okuda and Penedones (OP) put forward an intriguing proposal towards holography in asymptotically flat spacetimes (AFS). They showed that the flat space limi…
Large deflection scattering, soft radiation and KMOC formalism
Samim Akhtar, Alok Laddha, Arkajyoti Manna +1
KMOC (Kosower, Maybee, and O'Connell) formalism is an approach to analyze classical scattering in gauge theories and gravity using a class of ``inclusive'' observables which can be…
Towards the Parametric Renormalization of the S-matrix -- I
Pinaki Banerjee, Harsh, Alok Laddha
Zimmermann's forest formula is the corner stone of perturbative renormalization in QFT. By renormalizing individual Feynman graphs, it generates the UV finite S-matrix. This approa…
The Classical Super-Phaserotation Infrared Triangle
Sangmin Choi, Alok Laddha, Andrea Puhm
The universality of the logarithmic soft photon theorem in four dimensions can be traced to an infinite-dimensional asymptotic symmetry which acts as a local phase rotation on matt…
The Classical Super-Rotation Infrared Triangle
Sangmin Choi, Alok Laddha, Andrea Puhm
The universality of gravitational scattering at low energies and large distances encoded in soft theorems and memory effects can be understood from symmetries. In four-dimensional…
Restoring Causality in Higher Curvature Gravity
Jose D. Edelstein, Rajes Ghosh, Alok Laddha +1
Incorporating higher curvature terms into gravity theories modifies the classical field equations, potentially leading to theoretical issues like Shapiro time advancements that vio…
