Dynamic phase coexistence in glass–forming liquids
One of the most controversial hypotheses for explaining the heterogeneous dynamics of glasses postulates the temporary coexistence of two phases characterized by a high and by a low diffusivity. In this scenario, two phases with different diffusivities coexist for a time of the order of the relaxation time and mix afterwards. Unfortunately, it is difficult to measure the single-particle diffusi...
متن کاملCoexistence of proton-glass and ferroelectric order in Rb1-x(NH4)xH2AsO4.
The mixed crystal Rb~ —„(NH4)„HzAs04 (RADA) has been investigated for several values of x(x =0, 0.12, 0.15, and 0.20) by measuring the complex dielectric permittivity along the a tetragonal axis in the temperature range from 3 to 300 K and frequency range from 1 Hz to 30 kHz. We find coexistence of ferroelectric and proton-glass order in RADA for x =0.12 and probably at x 0.15. The long-range f...
متن کاملPhase Coexistence in Clusters
An analytical cluster wetting model is developed, based on minimization of an expression for the free energy, for solid-liquid equilibrium coexistence states in clusters. For given materials’ characteristic interfacial energies of the solid and liquid phases, the model relates the fraction of the solid-phase area wetted by the liquid to the volume fraction of the two phases. Equilibrium coexist...
متن کاملThree-Phase Coexistence in Lipid Membranes.
Phospholipid ternary systems are useful model systems for understanding lipid-lipid interactions and their influence on biological properties such as cell signaling and protein translocation. Despite extensive studies, there are still open questions relating to membrane phase behavior, particularly relating to a proposed state of three-phase coexistence, due to the difficulty in clearly disting...
متن کاملPhase coexistence in a forecasting game
Individual choices are either based on personal experience or on information provided by peers. The latter case, causes individuals to conform to the majority in their neighborhood. Such herding behavior may be very efficient in aggregating disperse private information, thereby revealing the optimal choice. However if the majority relies on herding, this mechanism may dramatically fail to aggre...
