Fluctuations and stochastic noise in systems with hyperbolic mass transport

Jou, David; Galenko, Peter - In: Physica A: Statistical Mechanics and its Applications 366 (2006) C, pp. 149-158

fluctuations of the solute density and the solute diffusion flux. The role of the diffusion flux is analyzed in two descriptions …A binary system in which the diffusion flux has a nonvanishing relaxation time is considered. We study the spectra of …. First, the shortest observable time interval is shorter than the flux relaxation time, and the diffusion flux behaves as …

Rods near curved surfaces and in curved boxes

Yaman, K.; Jeng, M.; Pincus, P.; Jeppesen, C.; Marques, C.M. - In: Physica A: Statistical Mechanics and its Applications 247 (1997) 1, pp. 159-182

We consider an ideal gas of infinitely rigid rods near a perfectly repulsive wall, and show that the interfacial tension of a surface with rods on one side is lower when the surface bends towards the rods. Surprisingly we find that rods on both sides of surfaces also lower the energy when the...

Labyrinthine patterns in a self-avoiding growing string

Kohyama, Tomotsu - In: Physica A: Statistical Mechanics and its Applications 233 (1996) 1, pp. 355-364

We propose a model of a self-avoiding growing string with excluded volume effects. In this model, the string develops to form a complex shape like a labyrinth. We find simple dynamical scaling relations for several characteristics quantities, including the radius of gyration and radius of...

Statistical mechanics of self-avoiding tethered membranes in the dense phase using collective coordinates

Daniels, D.R. - In: Physica A: Statistical Mechanics and its Applications 352 (2005) 2, pp. 436-446

We propose a theory for the statistical mechanics of a great many large, self-avoiding tethered membranes in the dense … spectrum for such a collection of membranes, and furthermore show that self-avoidance becomes effectively screened for tethered … membranes in the dense phase. A quantitative discussion of when the theoretical approach outlined in this work remains …

Unbinding transitions of membranes and strings from single and double-well potential

Asfaw, Mesfin - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 14, pp. 3526-3536

We present a theory of unbinding transitions for membranes that interact via short and long receptor/ligand bonds. The … detail of unbinding behaviour of the membranes is governed by the binding energies and concentrations of receptors and … ligands. We investigate the unbinding behaviour of these membranes with Monte Carlo simulations and via a comparison with …
