What does this research mean for the field?

Inference-time geometric interventions, specifically Dual Surgery, can deterministically suppress large language model hallucinations and restore factual knowledge across different model scales, rendering training-based alignment methods like DPO unnecessary. Novelty: ClaimNovelty.NOVEL_FINDING. Consensus alignment: ConsensusAlignment.CHALLENGES_CONSENSUS.

What question did this study set out to answer?

Abstract

This paper presents Project Aletheia, a systematic 165-phase investigation of LLM hallucination through the lens of condensed matter physics. Using GPT-2 (124M parameters) as a "particle accelerator" and scaling to Qwen2.5-14B, I establish eight fundamental laws, eight theorems, and six principles governing how transformers suppress factual knowledge—and how to deterministically restore it through inference-time geometric intervention.
