The stability of a quantum superposition of two different stationary mass distributions is examined, where the perturbing effect of each distribution on the space-time structure is taken into account, in accordance with the principles of general relativity. It is argued that the definition of the time-translation operator for the superposed space-times involves an inherent ill-definedness, leading to an essential uncertainty in the energy of the superposed state which, in the Newtonian limit… 
Relativistic Model for Gravity-Induced Quantum State Reduction
A Lorentz invariant model for gravity-induced quantum state reduction is presented, which is mainly developed from Penrose's argument that the time translation operator in a superposition of
On the Gravitization of Quantum Mechanics 1: Quantum State Reduction
This paper argues that the case for “gravitizing” quantum theory is at least as strong as that for quantizing gravity. Accordingly, the principles of general relativity must influence, and actually
The logical consistency of a description of quantum theory in the context of general relativity, which includes minimal coupling principle, is analyzed from the point of view of Feynman's formulation
Exact solutions of the newton-schrödinger equation, infinite derivative gravity and schwarzschild atoms
Various arguments have been put forward from time to time to support the view that quantum state reduction is a phenomenon that occurs objectively, because of some gravitational influence.1–6
Black holes, quantum theory and cosmology
Some reasons are given for believing that the rules of quantum (field) theory must be changed when general relativity becomes seriously involved. If full quantum mechanical respect is paid to the
Phenomenological analysis of quantum collapse as source of the seeds of cosmic structure
The standard inflationary version of the origin of the cosmic structure as the result of the quantum fluctuations during the early universe is less than fully satisfactory as has been argued in [A.
Probing a gravitational cat state
We investigate the nature of a gravitational two-state system (G2S) in the simplest setup in Newtonian gravity. In a quantum description of matter a single motionless massive particle can in

Rationale for a correlated worldline theory of quantum gravity
It is argued that gravity should cause a breakdown of quantum mechanics, at low energies, accessible to table-top experiments. It is then shown that one can formulate a theory of quantum gravity in
Structure of correlated worldline theories of quantum gravity
We consider the general form of "Correlated Worldline" (CWL) theories of quantum gravity. We show that one can have 2 different kinds of CWL theory, in which the generating functional is written as


Gravitation and quantum mechanics of macroscopic objects
SummaryThe problem of the reduction of the wave function in quantum theory is treated from a new standpoint. First, by combining Heisenberg's uncertainty relations with gravitation, quantitative limi
"Relative State" Formulation of Quantum Mechanics
The task of quantizing general relativity raises serious questions about the meaning of the present formulation and interpretation of quantum mechanics when applied to so fundamental a structure as

A new parameter-free unification of micro- and macrodynamics is constructed and gravitational measures for reducing macroscopic quantum fluctuations of the mass density are applied to lead to classical trajectories in the Macroscopic limit of translational motion.
Qualitative features of quantized gravitation
From a re-examination of a discussion by Bohr and Einstein of a gedanken experiment designed to violate the uncertainty relations, it is suggested that a qualitatively new feature of the merging
Classical equations for quantum systems.
This work investigates the requirements for coarse grainings to yield decoherent sets of histories that are quasiclassical, i.e., such that the individual histories obey, with high probability, effective classical equations of motion interrupted continually by small fluctuations and occasionally by large ones.

A linear equation of motion for the state vector is presented, in which an anti-Hermitian Hamiltonian that fluctuates randomly is added to the usual Hamiltonian of the Schr\"odinger equation. It is
Local quantum physics : fields, particles, algebras
This textbook gives a comprehensive account of local quantum physics understood as the synthesis of quantum theory with the principle of locality. Centered on the algebraic approach, it describes
In this paper, we shall show how the theory of measurements is to be understood from the point of view of a physical interpretation of the quantum theory in terms of hidden variables developed in a
