Phase separation in three-component lipid membranes: from Monte Carlo simulations to Ginzburg-Landau equations.

Preferential affinity of cholesterol for saturated rather than unsaturated lipids underlies the thermodynamic process of the formation of lipid nanostructures in cell membranes, that is, of rafts. In this context, phase segregation of two-dimensional ternary lipid mixtures is formally studied from two different perspectives. The simplest approach is based on Monte Carlo simulations of an Ising ...

Monte Carlo simulation of the dielectric susceptibility of Ginzburg-Landau mode relaxors

The electric dipole configuration and dielectric susceptibility of a Ginzburg-Landau model ferroelectric lattice with randomly distributed defects are simulated using the Monte Carlo method. The simulated characteristics of the lattice configuration and dielectric susceptibility indicate that the model lattice evolves from a normal ferroelectric state to a typical relaxor state with increasing ...

Monte Carlo Studies on Proton Computed Tomography using a Silicon Strip Detector Telescope

Monte Carlo computer programs such as the GEANT4 toolkit include precise models of particle interactions and can be an invaluable tool for studying the feasibility of new imaging techniques such as proton computed tomography (pCT). Presented in this paper is a comparison of laboratory data with GEANT4 predictions for the imaging characteristics of a simple metal object using a particle beam and...

(0,2) Landau-ginzburg Theory ⋆

A large class of (0,2) Calabi-Yau σ-models and Landau-Ginzburg orbifolds are shown to arise as different “phases” of supersymmetric gauge theories. We find a phenomenon in the Landau-Ginzburg phase which may enable one to understand which Calabi-Yau σ-models evade destabilization by worldsheet instantons. Examples of (0,2) LandauGinzburg vacua are analyzed in detail, and several novel features ...
