Daniel Sudarsky

Physicist at the Universidad Nacional Autónoma de México (UNAM) working on the foundations of quantum mechanics and semiclassical gravity. In the vault he is co-author, with Elias Okon and M. Wiedemann, of "Conservation in Every Quantum Measurement Outcome?" (arXiv:2610.29804, 2026), which critiques Collins & Popescu's proposal that a physical "preparer" system restores conservation exactly, outcome-by-outcome, in individual quantum measurements. He and Okon share an earlier joint paper with Tim Maudlin on the status of conservation laws and their implications for semiclassical gravity (2020), making this a sustained two-person research line rather than a single co-authorship.
