Ordering in charged rod fluids
The statistical mechanics of a dense fluid of charged rods is considered, and the corresponding phase diagram is calculated, using a collective coordinate transformation. A first-order isotropic-nematic phase transition is found, as suggested by a recent experiment. Collective coordinate transformations have been widely used in many different areas of physics. A well known example where they ar...
متن کاملThermal and hydrodynamic effects in the ordering of lamellar fluids.
Phase separation in a complex fluid with lamellar order has been studied in the case of cold thermal fronts propagating diffusively from external walls. The velocity hydrodynamic modes are taken into account by coupling the convection-diffusion equation for the order parameter to a generalized Navier-Stokes equation. The dynamical equations are simulated by implementing a hybrid method based on...
متن کاملEnhanced septahedral ordering in cold Lennard-Jones fluids.
We report molecular dynamics calculations on a two-component, cold, 15,625 particle, three-dimensional Lennard-Jones fluid. We calculated spherical harmonic components Q(LM) for the density of particles in the first coordination shell of each particle, as well as their spherical invariants , time-correlation functions, and wavelet density decompositions. The spherical invariants show that ...
متن کاملCell sorting is analogous to phase ordering in fluids.
Morphogenetic processes, like sorting or spreading of tissues, characterize early embryonic development. An analogy between viscoelastic fluids and certain properties of embryonic tissues helps interpret these phenomena. The values of tissue-specific surface tensions are consistent with the equilibrium configurations that the Differential Adhesion Hypothesis predicts such tissues reach after so...
متن کاملPhase transitions and ordering of confined dipolar fluids.
We apply a modified mean-field density functional theory to determine the phase behavior of Stockmayer fluids in slit-like pores formed by two walls with identical substrate potentials. Based on the Carnahan-Starling equation of state, a fundamental-measure theory is employed to incorporate the effects of short-ranged hard-sphere-like correlations while the long-ranged contributions to the flui...
