Reviving sub-keV warm dark matter: a UVLF-based analysis
Raymond T. Co, Siu Cheung Lam, Sai Chaitanya Tadepalli +1
Thermal warm dark matter (WDM) particles with are ruled out at more than by multiple observational probes, owing to the strong suppression of…
Warm Dark Matter meets Cold Dark Matter Isocurvature
Sai Chaitanya Tadepalli, Tomo Takahashi
Isocurvature fluctuations can be generated in various scenarios in the early Universe. In particular, some specific models predict those with a blue-tilted spectrum, which is consi…
Test-time Scaling Techniques in Theoretical Physics -- A Comparison of Methods on the TPBench Dataset
Zhiqi Gao, Tianyi Li, Yurii Kvasiuk +5
Large language models (LLMs) have shown strong capabilities in complex reasoning, and test-time scaling techniques can enhance their performance with comparably low cost. Many of t…
Theoretical Physics Benchmark (TPBench) -- a Dataset and Study of AI Reasoning Capabilities in Theoretical Physics
Daniel J. H. Chung, Zhiqi Gao, Yurii Kvasiuk +5
We introduce a benchmark to evaluate the capability of AI to solve problems in theoretical physics, focusing on high-energy theory and cosmology. The first iteration of our benchma…
Non-Gaussianity from explicit -breaking interactions
Raymond T. Co, Taegyu Lee, Sai Chaitanya Tadepalli
We investigate primordial non-Gaussianity (NG) arising from the explicit symmetry-breaking interactions during inflation involving a nearly massless axial component of a com…
