Schrödinger–Newton Equation with Spontaneous Wave Function Collapse
Autor: Lajos Diósi
Publikováno v: Quantum Reports, Vol 4, Iss 4, Pp 566-573 (2022)
Based on the assumption that the standard Schrödinger equation becomes gravitationally modified for massive macroscopic objects, two independent proposals have survived from the 1980s. The Schrödinger–Newton equation (1984) provides well-localize

Underground test of gravity-related wave function collapse
Autor: Matthias Laubenstein, Angelo Bassi, Catalina Curceanu, Kristian Piscicchia, Sandro Donadi, Lajos Diósi
Publikováno v: Nature Physics
Roger Penrose proposed that a spatial quantum superposition collapses as a back-reaction from spacetime, which is curved in different ways by each branch of the superposition. In this sense, one speaks of gravity-related wave function collapse. He al

Fundamental Irreversibility: Planckian or Schrödinger–Newton?
Autor: Lajos Diósi
Publikováno v: Entropy, Vol 20, Iss 7, p 496 (2018)
The concept of universal gravity-related irreversibility began in quantum cosmology. The ultimate reason for universal irreversibility is thought to come from black holes close to the Planck scale. Quantum state reductions, unrelated to gravity or re

General Wick's theorem for bosonic and fermionic operators
Autor: Lajos Diósi, Luca Ferialdi
Publikováno v: Phys. Rev. A
Wick's theorem provides a connection between time ordered products of bosonic or fermionic fields, and their normal ordered counterparts. We consider a generic pair of operator orderings and we prove, by induction, the theorem that relates them. We n

Two Invariant Surface-Tensors Determine CSL of Massive Body Wave Function
Autor: Lajos Diósi
Publikováno v: Fundamental Theories of Physics ISBN: 9783030467760
Decoherence of massive body wave function under Continuous Spontaneous Localization is reconsidered. It is shown for homogeneous probes with wave functions narrow in position and angle that decoherence is a surface effect. Corresponding new surface i
