Interface stability, interface fluctuations, and the Gibbs-Thomson relationship in motility-induced phase separations.
Minimal models of self-propelled particles with short-range volume exclusion interactions have been shown to exhibit the signatures of phase separation. Here I show that the observed interfacial stability and fluctuations in motility-induced phase separations (MIPS) can be explained by modeling the microscopic dynamics of the active particles in the interfacial region. In addition, I demonstrat...
متن کاملEQUILIBRIUM FLUCTUATIONS FORr ' INTERFACE
We study the large scale space{time uctuations of an interface which is modeled by a massless scalar eld with reversible Langevin dynamics. For a strictly convex interaction potential we prove that on a large space{time scale these uc-tuations are governed by an innnite-dimensional Ornstein-Uhlenbeck process. Its eeective diiusion type covariance matrix is characterized through a variational fo...
متن کاملInterface fluctuations under shear.
Coarsening systems under uniform shear display a long time regime characterized by the presence of highly stretched and thin domains. The question then arises whether thermal fluctuations may actually destroy this layered structure. To address this problem in the case of nonconserved dynamics, we study an anisotropic version of the Burgers equation, constructed to describe thermal fluctuations ...
متن کاملMetal-molecule interface fluctuations.
We have created self-assembled circular chains of C60 laterally bound to a layer of Ag atoms as a model system for characterizing fluctuations at a metal-molecule interface. STM measurements show that the Ag and C60 sides of the interface fluctuate independently, with frequency-dependent amplitudes of magnitude 0.1 nm at approximately 1 Hz for the Ag edge and approximately 0.01 Hz for the C60 r...
متن کاملAn Algorithm based on Predicting the Interface in Phase Change Materials
Phase change materials are substances that absorb and release thermal energy during the process of melting and freezing. This characteristic makes phase change material (PCM) a favourite choice to integrate it in buildings. Stephan problem including melting and solidification in PMC materials is an practical problem in many engineering processes. The position of the moving boundary, its veloci...
