A healthier semi-classical dynamics. (arXiv:2208.11722v1 [quant-ph]) 上午10:02 | Isaac Layton, Jonathan Oppenheim, Zachary Weller-Davies | quant-ph updates on arXiv.org We study the back-reaction of quantum systems onto classical ones. Taking the starting point that semi-classical physics should be described at all times by a point in classical phase space and a quantum state in Hilbert space, we consider an unravelling… Read more →

Can the Many-Worlds Interpretation be probed in Psychology?

Heinrich Päs (Technische Universität Dortmund) A minimal approach to the measurement problem and the quantum-to-classical transition assumes a universally valid quantum formalism, i.e. unitary time evolution governed by a Schrödinger-type equation. As had been pointed out long ago, in this view the measurement process can be described by decoherence which results in a “Many-Worlds” or “Many-Minds” scenario according to Everett and Zeh. A silent… Read more →
