Collective excitations in liquids are important for understanding liquid dynamical and thermodynamic properties. Gapped momentum states (GMS) a notable feature of dynamics predicted to operate the transverse collective excitations. Here, we combine inelastic neutron scattering experiments, theory, molecular modeling study GMS Ga wide range temperature $k$ points. We find that all three lines enquiry agree longitudinal dynamics. In dynamics, experiments with modeling, as well earlier x-ray at...
The physics of supercritical states is understood to a much lesser degree compared subcritical liquids. Carbon dioxide, in particular, has been intensely studied, yet little known about the part its phase diagram. Here, we combine neutron scattering experiments and molecular dynamics simulations demonstrate structural crossover at Frenkel line. seen pressures as high 14 times critical pressure evidenced by changes main features structure factor pair distribution functions.
A hallmark of a thermodynamic phase transition is the qualitative change system properties such as energy and heat capacity. On other hand, no thought to operate in supercritical state matter and, for this reason, it was believed that vary smoothly without any changes. Here, we perform extensive molecular dynamics simulations wide temperature range find deeply thermodynamically heterogeneous, witnessed by different dependence energy, capacity its derivatives at low high temperature.
