Quantum theory as an emergent phenomenon : the statistical mechanics of matrix models as the precursors of quantum field theory

Quantum mechanics is our most successful physical theory. However, it raises conceptual issues that have perplexed physicists and philosophers of science for decades. This 2004 book develops an approach, based on the proposal that quantum theory is not a complete, final theory, but is in fact an emergent phenomenon arising from a deeper level of dynamics. The dynamics at this deeper level are taken to be an extension of classical dynamics to non-commuting matrix variables, with cyclic permutation inside a trace used as the basic calculational tool. With plausible assumptions, quantum theory is shown to emerge as the statistical thermodynamics of this underlying theory, with the canonical commutation/anticommutation relations derived from a generalized equipartition theorem. Brownian motion corrections to this thermodynamics are argued to lead to state vector reduction and to the probabilistic interpretation of quantum theory, making contact with phenomenological proposals for stochastic modifications to Schrödinger dynamics.

This book develops a new approach based on the proposal that quantum theory is not a complete, final theory, but, in fact, an emergent phenomenon arising from a more profound level of dynamics. Quantum mechanics is our most successful physical theory but raises conceptual issues that perplex physicists and philosophers of science. This book develops an approach, based on the proposal that quantum theory is not a complete, final theory, but in fact an emergent phenomenon arising from a deeper level of dynamics Stephen Adler tackles the perplexing conceptual issues raised by the quantum theory of mechanics. He develops a new approach to the subject, based on the proposal that quantum theory is not a complete, final theory, but is an emergent phenomenon arising from a deeper level of dynamics In this chapter we set up a classical Lagrangian and Hamiltonian dynamics for matrix models.
