Lost in the Middle at Birth: An Exact Theory of Transformer Position Bias
Borun D Chowdhury
The ``Lost in the Middle'' phenomenon -- a U-shaped performance curve where LLMs retrieve well from the beginning and end of a context but fail in the middle -- is widely attribute…
FeynTune: Large Language Models for High-Energy Theory
Paul Richmond, Prarit Agarwal, Borun Chowdhury +2
We present specialized Large Language Models for theoretical High-Energy Physics, obtained as 20 fine-tuned variants of the 8-billion parameter Llama-3.1 model. Each variant was tr…
Intergalactic magnetic field spectra from diffuse gamma rays
Wenlei Chen, Borun D. Chowdhury, Francesc Ferrer +2
Non-vanishing parity-odd correlators of gamma ray arrival directions observed by Fermi-LAT indicate the existence of a helical intergalactic magnetic field (Tashiro et al.2013). We…
Hawking Evaporation is Inconsistent with a Classical Event Horizon at
Borun D. Chowdhury, Lawrence M. Krauss
A simple classical consideration of black hole formation and evaporation times focusing solely on the frame of an observer at infinity demonstrates that an infall cutoff outside th…
When UV and IR Collide: Inequivalent CFTs From Different Foliations Of AdS
Borun D. Chowdhury, Maulik K. Parikh
In the AdS/CFT correspondence, CFTs are identified by asymptotic boundary surfaces and the boundary conditions imposed on those surfaces. However, AdS can be foliated in various wa…
Entwinement and the emergence of spacetime
Vijay Balasubramanian, Borun D. Chowdhury, Bartlomiej Czech +1
It is conventional to study the entanglement between spatial regions of a quantum field theory. However, in some systems entanglement can be dominated by "internal", possibly gauge…
