Unveiling a Hidden Chapter in Physics
On October 23, at 17:17, an unpublished manuscript by Erwin Schrödinger, preserved for over 80 years in the archives of the University of Vienna, has come to light revealing an alternative hidden-variable framework to explain quantum phenomena. Flavio Del Santo, a researcher at the University of Geneva, examined this three-page document and confirmed its mathematical consistency with established quantum mechanics.
Written sometime after November 1944, Schrödinger never published this work, possibly due to his awareness of Pelzer’s earlier research. In this manuscript, Schrödinger proposes a hidden property of photons that can assume multiple values. This contribution revisits debates from the 1940s about the fundamental nature of quantum randomness. Schrödinger himself had long held a view, dating back to the 1920s, that the laws of nature are statistical in character, highlighting his sustained interest in the subject.
Historical Background and Impact
In 1932, John von Neumann presented arguments against hidden-variable theories, and in 1943, Edmund Taylor Whittaker explored examples involving polarizers in this context. Yet Schrödinger’s model aligns with quantum mechanical predictions, even when light passes through multiple polarizers. The findings by Flavio Del Santo have been published on the preprint server arXiv, opening fresh avenues for research in the field.
This discovery underscores the value of revisiting scientific heritage and how overlooked ideas can gain renewed significance. Schrödinger’s model offers a fresh perspective on longstanding questions about randomness and determinism in nature. It has the potential to inspire new experiments and theoretical developments that could reshape our understanding of quantum phenomena.
