Zhonghao Lu

Philosopher of physics, triple-affiliated in the header of the captured paper with LMU Munich, the University of Pittsburgh, and Peking University; author of the 2026 preprint "Unbounded Operators, Physicality, and Modality in Quantum Theories" (arXiv:2609.28136). Matters to this vault as the author of its own first foray into the Hilbert-space-physicality debate: his paper's thesis (the full Hilbert space is physical) and his own positive proposal, θ-Intermediatism — a hierarchical, degreed view of physicality — anchor three of the vault's new claim-notes. A fourth note documents an unrelated finding about the same paper: his own bibliography cites the wrong arXiv identifier for the paper his whole argument rebuts.
