Enhancing FKG.in: automating Indian food composition analysis
Saransh Kumar Gupta, Lipika Dey, Partha Pratim Das +2
This paper presents a novel approach to compute food composition data for Indian recipes using a knowledge graph for Indian food (FKG[.]in) and LLMs. The primary focus is to provid…
Lattice simulations of axion-U(1) inflation: gravitational waves, magnetic fields, and scalar statistics
Ramkishor Sharma, Axel Brandenburg, Kandaswamy Subramanian +1
We numerically study axion-U(1) inflation, focusing on the regime where the coupling between axions and gauge fields results in significant backreaction from the amplified gauge fi…
Superspace invariants and correlators in 4d superconformal field theories
Aditya Jain, Amin A. Nizami
Using polarization spinor methods in conjunction with the superspace formalism, we construct 3-point superconformal invariants that are used to determine the form of 3-point correl…
A generalized method of constraining Warm Inflation with CMB data
Umang Kumar, Suratna Das
A thorough MCMC analysis of any inflationary model against the current cosmological data is essential for assessing the validity of such a model as a viable inflationary model. War…
Reassessing constant-roll Warm Inflation
Sandip Biswas, Kaushik Bhattacharya, Suratna Das
Departing from standard slow-roll conditions is one way of putting the inflationary paradigm to test, and constraining the dynamics of the inflaton field with a constant-rate of ro…
Spread complexity and quantum chaos for periodically driven spin chains
Amin A. Nizami, Ankit W. Shrestha
The complexity of quantum states under dynamical evolution can be investigated by studying the spread with time of the state over a pre-defined basis. It is known that this complex…
