CosmoAgent: AI Agent for Theoretical Cosmology
Stephon Alexander, Loukas Gouskos, Savvas M. Koushiappas +2
We present CosmoAgent, an agentic AI framework using large language models (LLMs) to search for dark-energy and modified-gravity models. We define a covariant grammar that allows L…

Macroscopic Feynman Cycles and Poisson--Kingman Universality in Bose Condensation
Wen Sun
We prove a canonical limit theorem for the macroscopic Feynman cycles of finite-volume ideal Bose gases. Cycles carry marks in a general Polish space , encoding spatial…

Symbiotic Magnetogenesis during Radiation Domination
Stephon Alexander, Ariel Marxena Baksh, Lawrence Edmond +1
We present a late-time magnetogenesis mechanism in which a coupled axion-dilaton system sources a dark gauge field. The dilaton's exponential coupling drives tachyonic ampli…
