  1. How many degrees of freedom describe a quantum N-particle state?

    quant-ph 2026-07 conditional novelty 7.0 of 10

    For closed quantum N-particle systems all 3N canonical degrees of freedom are physical; the frame degrees of freedom that relational models discard reappear as non-Heisenberg terms in generalised uncertainty relations...

  2. Counterfactuals in Macroscopic Quantum Physics: Irreversibility, Measurement and Locality

    quant-ph 2025-05 conditional novelty 6.0 of 10

    Counterfactual reasoning yields a unitary model of constructor-based irreversibility, an incoherent homogenizer, new limits on work extraction from coherence, and a von Neumann entropy measure of locally inaccessible ...
