W*-Dynamics of Infinite Dissipative Quantum Systems

Geoffrey L. Sewell

We formulate the dynamics of an infinitely extended open dissipative quantum system, ${Σ]$,in the Schroedinger picture.The generic model on which this is based comprises a C*-algeb…

Macroscopic Observables, Thermodynamic Completeness and the Differentiability of Entropy

Geoffrey L. Sewell

We provide a quantum statistical basis for (a)a characterisation of a complete set of thermodynamic variables and (b) the differentiability of the entropy function of these variabl…

Model of Antiferromagnetic Superconductivity

Geoffrey L. Sewell

We present a simple model that supports superconductive and antiferromagnetic ordering. The model consists of a system of electrons on a simple cubic lattice that move by tunnel ef…

Hyperbolic Flows and the Question of Quantum Chaos

Geoffrey L. Sewell

Hyperbolic flows, as formulated by Anosov, are the prototypes of chaotic evolutions in classical dynamical systems. Here we provide a concise updated account of their quantum count…

Local Thermodynamic Equilibrium at Three Levels

Geoffrey L. Sewell

We present coordinated formulations of local thermodynamical equilibrium conditions at three levels, namely the macroscopic one of classical thermodynamics, the mesoscopic one of h…

Macrostatistics and Fluctuating Hydrodynamics

Geoffrey L. Sewell

We extend our earlier macrostatistical treatment of hydrodynamical fluctuations about nonequilibrium steady states to viscous fluids. Since the scale dependence of the Navier-Stoke…
