• Abstract: We propose a novel solution to the measurement problem based on quantum field theory and Haag's theorem. According to our proposal in elementary interactions where the particles content is changed, the temporal evolution is non unitary. These interactions which are almost instantaneous lead to a genuine stochastic selection of an outcome subspace that has a distinct particles content but can be a superposition of momentum states, spin states, etc.

  Locality holds for the quantum theory, and seems to be fully obeyed also by the classical treatment. We do discuss extensively the distinction between the quantum treatment and the classical one, even though they produce exactly the same equations mathematically. It is suggested to apply this theory for real time quantum model simulations.

  We show that decoherence due to the presence of a detector propagates with the speed of light in terms of a retarded Green's function. The quantum nature of fields, such as quantum fluctuations or emission of gravitons expressed in terms of the Keldysh Green's function also play important roles in the mechanism of decoherence due to on-shell particle creation.

  entropy of cosmological perturbations can be studied by treating them in the framework of squeezed quantum systems. We compute the covariance matrix elements of the parametric quantum field and solve for the evolution of the density matrix elements. We show explicitly why the entropy for the squeezed yet closed system is zero, but is proportional to the particle number produced.

  Two particles are identical if all their intrinsic properties, such as spin and charge, are the same. Quantum mechanics is seen as a normative and algorithmic theory guiding an agent to assess her subjective beliefs represented as (coherent) sets of gambles. We show how sets of exchangeable observables (gambles) may be updated after a measurement and discuss the issue of defining entanglement for indistinguishable particle systems.
