Linearity of quantum mechanics
NettetEbook. Volume 197: Foundations of Quantum Theory. Abstract. We obtain the Schrödinger equation from the Hamilton-Jacobi equation of classical mechanics together with the law of conservation of matter. It is the quantum current in this continuity equation which ensures the linearity of quantum mechanics. $35.00 / €27.50 / £22.00. Nettet27. aug. 2024 · Furthermore, nonlinear modifications of quantum mechanics generically enable quickly solving hard computational problems such as performing unstructured search among n items in time poly (log n). Indeed, the search lower bound ( 17 ) can be used to show that nonlinear dynamics is exponentially difficult to simulate in general ( …

NettetIn many quantum systems of contemporary interest, the DNLSE arises as a result of approximate descriptions despite the fundamental linearity of quantum mechanics. Such scenarios, exemplified by polaron physics and Bose-Einstein condensation, provide application areas for the theoretical tools developed in this text. Nettet7. "By the linearity of quantum mechanics" is actually a reference to the linearity of the operators used it quantum mechanics. It means that, for a linear operator A (by the very definition of linearity), A ( α Ψ + β Φ ) = α A Ψ + β A Φ , where α and β are …
NettetI argue that the linearity of quantum mechanics is an emergent feature at the Planck scale, along with the manifold structure of space-time. In this regime the usual causality violation objections to nonlinearity do not apply, and nonlinear effects can be of comparable magnitude to the linear ones and still be highly suppressed at low …
