Theory of Fluctuations in Pseudointegrable Systems

Physical Review Letters, 1993
We provide a sum rule for the length spectrum of pseudointegrable systems in terms of the quantal energies. Further, we derive an expression for the form factor and infer the dependence of spectral fluctuations on the geometry of the system. Our analysis allows us to explain various numerical results obtained in recent years.

Theory of Fluctuations in Superconductors

2005
Abstract This book presents itself as both an encyclopedia and a textbook of fluctuation phenomena in superconductors. The first half presents the phenomenological methods of the Ginzburg-Landau theory and microscopical methods of the quantum field theory in the description of fluctuations. The second half provides a wide panorama of the

A Theory of Commodity Price Fluctuations

Journal of Political Economy, 1996
This paper studies the price fluctuations of storable commodities that are traded in open markets and are subject to random shocks to demand or, more particularly, to supply. It relaxes the common assumption that the shocks are identically and independently distributed in favor of temporally dependent and periodic disturbances.

On the Formalism of Thermodynamic Fluctuation Theory

Physical Review, 1951
From the statistical mechanical occupation probability of microstates Einstein has inferred a distribution function for the macroscopic states of a canonical ensemble. The conventional theory of thermodynamic fluctuations proceeds by making certain series expansions in the Einstein function and by dropping all cubic and higher order terms.

A mechanochemical theory of fluctuations in muscles

Biorheology, 1974
Equations of motions for the z-bands of a striated muscle in isometric tetanus arc written. The different kinds of forces acting on the z-bands arc considered and their properties discussed. Included arc the mechanochemical force, a damping force, and a spring force.
