Statistical mechanics of polyampholytes

Physical Review E, 1994
Polyampholytes are polymers with a random sequence of positive and negative charges along their backbone. We examine the question of whether such polymers swell or contract due to Coulomb interactions, by Monte Carlo simulations and analytical arguments.

Statistical Mechanics for a Class of Quantum Statistics

Physical Review Letters, 1994
Generalized statistical distributions for identical particles are introduced for the case where filling a single-particle quantum state by particles depends on filling states of different momenta. The system of one-dimensional bosons with a two-body potential that can be solved by means of the thermodynamic Bethe ansatz is shown to be equivalent ...

Statistical Mechanics of Irreversibility

Physical Review, 1952
The fluctuation-dissipation theorem relating spontaneous equilibrium fluctuations to the conductance in a dissipative thermodynamic system is extended to the case of several variables, using a quantum statistical analysis. The conductance matrix is shown to be subject to certain symmetry relations, providing a generalization of the Onsager reciprocity ...

Statistical mechanics of cracks

Physical Review E, 1996
This paper describes a formalism designed to answer questions about Hamiltonian systems in contact with a heat bath. The formalism is applied to a simple model of fracture to find, first, the rate at which a crack creeps through a brittle body as a result of thermal fluctuations and, second, the rate at which the crack jumps from creeping to rapid ...

Generalized Statistical Mechanics

Physical Review, 1951
In this paper, a start is made toward the development of a statistical mechanics that will be suited to the treatment of dynamic changes in thermodynamic systems and which, at the same time, will be in the appropriate form for a relativistically invariant theory.
