Fokker-Planck-Poisson kinetics: Multi-phase flow beyond equilibrium

Multi-phase phenomena remain at the heart of many challenging fluid dynamics problems. Molecular fluxes at the interface determine the fate of neighboring phases, yet their closure far from the continuum needs to be modeled. Along the hierarchy of kinetic ...

Relation between a heterogeneous percolation model for cylinders and phase separation in the lattice fluid problem

Claudio Grimaldi

A relationship based upon analogy is explored between (i) a lattice-based model for percolation by cylinders that employs distinct site types with unequal occupation probabilities in order to capture heterogeneities in the particle dispersion, and (ii) the ...

Can we approach the gas-liquid critical point using slab simulations of two coexisting phases?

Dominic John Tildesley

In this paper, we demonstrate that it is possible to approach the gas-liquid critical point of the Lennard-Jones fluid by performing simulations in a slab geometry using a cut-off potential. In the slab simulation geometry, it is essential to apply an accu ...

Direct observation of nanoscale interface phase in the superconducting chalcogenide KxFe2-ySe2 with intrinsic phase separation

Davide Innocenti

We have used scanning micro x-ray diffraction to characterize different phases in superconducting KxFe2-ySe2 as a function of temperature, unveiling the thermal evolution across the superconducting transition temperature (T-c similar to 32 K), phase separa ...

Chains of mean-field models

Rüdiger Urbanke, Nicolas Macris, Seyed Hamed Hassani

We consider a collection of Curie-Weiss (CW) spin systems, possibly with a random field, each of which is placed along the positions of a one-dimensional chain. The CW systems are coupled together by a Kac-type interaction in the longitudinal direction of ...

Connecting the microdynamics to the emergent macrovariables: Self-organized criticality and absorbing phase transitions in the deterministic lattice gas

Andrea Giometto

We reinvestigate the Deterministic Lattice Gas introduced as a paradigmatic model of the 1/f spectra arising according to the self-organized criticality scenario. We demonstrate that the density fluctuations exhibit an unexpected dependence on systems size ...

Metastability of two-dimensional vortex glass in Bi2Sr2CaCu2O8+delta

László Forró, Helmuth Berger

The decoupled layer quasi-two-dimensional glass phase of c-axis vortices in optimally doped Bi2Sr2CaCu2O8+delta (BSCCO) exhibits low-temperature metastability, the onset temperature of which is coincident with the peak in depinning current for zero-field-c ...

Stress-induced and atomic ordering in 18-carat Au-Cu-Ag alloys

Daniele Mari, Robert Schaller, John Hennig

Atomic ordering and stress-induced ordering (Zener relaxation) were studied in a series of 18-carat (75 wt%) yellow gold alloys (Au-Cu-Ag) by means of isothermal mechanical spectroscopy with a forced torsion pendulum at low frequencies. In the high-tempera ...
