Phase separation of a multiple occupancy lattice gas
A binary lattice gas model that allows for multiple occupancy of lattice sites, inspired by recent coarse-grained descriptions of solutions of interacting polymers, is investigated by combining the steepest descent approximation with an exploration of the multidimensional energy landscape and by Gibbs ensemble Monte Carlo simulations. The one-component version of the model, involving on site an...
متن کاملA Lattice Model of Charge-Pattern-Dependent Polyampholyte Phase Separation.
In view of recent intense experimental and theoretical interests in the biophysics of liquid-liquid phase separation (LLPS) of intrinsically disordered proteins (IDPs), heteropolymer models with chain molecules configured as self-avoiding walks on the simple cubic lattice are constructed to study how phase behaviors depend on the sequence of monomers along the chains. To address pertinent gener...
متن کاملNuclear liquid-gas phase transition within the lattice gas model
We study the nuclear liquid-gas phase transition on the basis of a two-component lattice gas model. A Metropolis type of sampling method is used to generate microscopic states in the canonical ensemble. The effective equation of state and fragment mass distributions are evaluated in a wide range of temperatures and densities. A definition of the phase coexistence region appropriate for mesoscop...
متن کاملPairing and phase separation in a polarized Fermi gas.
We report the observation of pairing in a gas of atomic fermions with unequal numbers of two components. Beyond a critical polarization, the gas separates into a phase that is consistent with a superfluid paired core surrounded by a shell of normal unpaired fermions. The critical polarization diminishes with decreasing attractive interaction. For near-zero polarization, we measured the paramete...
متن کاملNonequilibrium Phase Transitions in a Simple Three-State Lattice Gas
We investigate the dynamics of a three-state stochastic lattice gas consisting of holes and two oppositely "charged" species of particles, under the influence of an "electric" field at zero total charge. Interacting only through an excludedvolume constraint, particles exchange with holes and, on a slower time scale, with each other. Using a combination of Monte Carlo simulations and meanfield e...
