Within the inherent structure thermodynamic formalism introduced by Stillinger and Weber [Phys. Rev. A 25, 978 (1982)]], we address the basic question of the physics of the liquid-liquid transition and of density maxima observed in some complex liquids such as water by identifying, for the first time, the statistical properties of the potential energy landscape responsible for these anomalies. ...

a three-parameter cubic equation of state has been proposed for predicting pvt of pure refrigerantssuch as r236ea, r236fa, r245fa, r245ca, r218, r227ea, and r717, from freezing point up to critical pointtemperature and pressures up 650 atm. we explore the theory of the equation of state from the view pointof ihm–song–mason (ism) equation of state, which has been derived on the basis of statisti...

Water is hypothesized to have a low temperature phase transition line which separates a high density water at high temperatures from a low density water at low temperatures. This negatively sloped first order liquid-liquid phase coexistence line terminates at a critical point known as the liquid-liquid critical point. This critical point is hypothesized to exist in a deeply supercooled region o...

Liquid marble is a liquid droplet coated with particles. Recently, the evaporation process of a sessile liquid marble using geometric measurements has attracted great attention from the research community. However, the lack of gravimetric measurement limits further insights into the physical changes of a liquid marble during the evaporation process. Moreover, the evaporation process of a marble...

in this work an analytical equation of state has been employed to calculate the pvt properties ofternary refrigerant mixtures. the theoretical eos is that of ihm, song and mason, which is based onstatistical-mechanical perturbation theory, and the two constants are enthalpy of vaporization δhvapand molar density ρnb, both at the normal boiling temperature. the following three temperaturedepende...

Combining molecular dynamics (MD) simulation and Voronoi polyhedral analyses, we discussed the microstructure evolution in liquid and glassy silicon during cooling by focusing on the fraction of various clusters. Liquid-liquid phase transition (LLPT) is detected in supercooled liquid silicon However, freezing the high-density liquid (HDL) to the glassy state is not achieved as the quenching rat...

Although H2O has been the topic of considerable research since the beginning of the century, its peculiar physical properties are still not well understood. We discuss recent experiments and simulations relating to the hypothesis that, in addition to the known critical point in water (below which two fluid phases — a lower-density gas and a higher-density liquid — coexist), there exists a “seco...

In bulk Fermi liquids such as liquid He and nuclear matter the quasiparticle effective mass is enhanced at the Fermi surface and reduces to the bare mass far from the Fermi surface. We incorporate this central physical feature into the density and spin-density dynamics of normal-liquid He and obtain good agreement with recent high-resolution neutron-scattering experiments. Existing theories up ...
