Nonlinear Quantum Mechanics and Artificial Intelligence
Jonathan Oppenheim
We examine a criterion for relativistic covariance of nonlinear quantum field theory recently proposed by GPT-5 and published in Physics Letters B. We show that this criterion inad…

Classical gravity cannot mediate entanglement
Chiara Marletto, Jonathan Oppenheim, Vlatko Vedral +1
In Nature, 646, 813 (2025), Aziz and Howl claim that classical (unquantised) gravity produces entanglement. We show that their model does not produce entanglement. Even if the mode…

A Spin-Based Pathway to Testing the Quantum Nature of Gravity
Sougato Bose, Anupam Mazumdar, Roger Penrose +52
A key open problem in physics is the correct way to combine gravity (described by general relativity) with everything else (described by quantum mechanics). This problem suggests t…
