Beables/Observables in Classical and Quantum Gravity

Observables ‘are observed’ whereas beables just ‘are’. This gives beables more scope in the cosmological and quantum domains. Both observables and beables are entities that form ‘brackets’ with ‘the constraints’ that are ‘equal to’ zero. We explain how depending on circumstances, these could be, e.g., Poisson, Dirac, commutator, histories, Schouten–Nijenhuis, double or Nambu brackets, first-cla...

Ii Classical and Nonclassical Compo - Nents of Quantum Observables 3

The Heisenberg inequality ∆X∆P ≥ h̄/2 can be replaced by an exact equality, for suitably chosen measures of position and momentum uncertainty, which is valid for all wavefunctions. The significance of this “exact” uncertainty relation is discussed, and results are generalised to angular momentum and phase, photon number and phase, time and frequency, and to states described by density operators....

Inconclusive Quantum Measurements and Decisions under Uncertainty

We give a mathematical definition for the notion of inconclusive quantum measurements. In physics, such measurements occur at intermediate stages of a complex measurement procedure, with the final measurement result being operationally testable. Since the mathematical structure of Quantum Decision Theory (QDT) has been developed in analogy with the theory of quantum measurements, the inconclusi...

Forward and backward time observables for quantum evolution and quantum stochastic processes -I: The time observables

Given a Hamiltonian H on a Hilbert space H it is shown that, under the assumption that σ(H) = σac(H) = R , there exist unique positive operators TF and TB registering the Schrödinger time evolution generated by H in the forward (future) direction and backward (past) direction respectively. These operators may be considered as time observables for the quantum evolution. Moreover, it is shown tha...

Determinate Values for Quantum Observables

This is a comment on J. A. Barrett’s article “The Preferred-Basis Problem and the Quantum Mechanics of Everything” in Brit. J. Phil. Sci. 56 (2005), which concerns theories postulating that certain quantum observables have determinate values, corresponding to additional (often called “hidden”) variables. I point out that it is far from clear, for most observables, what such a postulate is suppo...
