Classicality via hydrodynamics in quantum field theory

نویسنده

  • C. Anastopoulos
چکیده

Motivated by ideas from the consistent histories approach to quantum mechanics, we examine a simple model of hydrodynamic coarse graining for a scalar field. It consists in averaging the field over spatial regions of size L and constructing the evolution equations for the coarse grained quantities, identifying dissipation and noise.

Information measures and classicality in quantum mechanics

We study information measures in quantum mechanics, with the particular emphasis on providing a quantification of the notion of predictability and classicality. Our primary tool is the Shannon Wehrl entropy I. We give a precise criterion for phase space classicality of states and argue that in view of this a) I provides a good measure for the degree of deviation from classicality in closed syst...

Classicality in Quantum Mechanics

In this article we propose a solution to the measurement problem in quantum mechanics. We point out that the measurement problem can be traced to an a priori notion of classicality in the formulation of quantum mechanics. If this notion of classicality is dropped and instead classicality is defined in purely quantum mechanical terms the measurement problem can be avoided. We give such a definit...

Emergence of Classicality in Quantum Phase Transitions

We show that classicality emerges during quantum phase transtions due to parametric interactions without coupling to environments. The Wigner functions are explicitly calculated for the Gaussian vacuum, number, and thermal states of a free scalar field that describes the spinodal instability regime. The Wigner functions are sharply peaked around their classical trajectories during the phase tra...

Emergence of a classical Universe from quantum gravity and cosmology

I describe how we can understand the classical appearance of our world from a universal quantum theory. The essential ingredient is the process of decoherence. I start with a general discussion in ordinary quantum theory and then turn to quantum gravity and quantum cosmology. There is a whole hierarchy of classicality from the global gravitational field to the fluctuations in the cosmic microwa...
