AI-powered scientists are starting to take off! This paper introduces PHYSMASTER, an LLM-based agent designed to operate as an autonomous theoretical and computational physicist. The goal is to go from an AI co-scientist to an autonomous AI scientist in fundamental physics. PHYSMASTER uses Monte Carlo Tree Search for adaptive exploration, hierarchical agent collaboration for complex tasks, and LANDAU, a layered knowledge base preserving retrieved papers, curated prior knowledge, and validated methodology traces for reuse. Five case studies spanning from the cosmos to elementary particles demonstrate its capability: Two acceleration cases: PHYSMASTER compressed labor-intensive engineering work that typically takes a senior PhD 1-3 months into less than 6 hours. Two automation cases: Given human-specified hypotheses, PHYSMASTER executed end-to-end exploration loops in 1 day rather than unpredictable months. One autonomous discovery case: PHYSMASTER independently explored an open problem in semi-leptonic decays of charmed mesons, constructing the effective Hamiltonian and predicting decay amplitudes using SU(3) flavor symmetry.
