A rare gas mixture: From rigid to gas-like fluid by a mutual concentration change
Yu. D. Fomin, E. N. Tsiok, V. N. Ryzhov +1
For a number of mixtures of rate gases at high pressures, sound speed minima are experimentally observed depending on the concentration. This behavior has not yet been explained. W…
The influence of Gaussian pinning on the melting scenario of a two-dimensional soft-disk system: First-Order versus Continuous Transition
Yu. D. Fomin, Eu. A. Gaiduk, E. N. Tsiok +1
Two-dimensional systems are realized experimentally as thin layers on a substrate. The substrate can have some imperfections (defects of the crystalline structure, chemical impurit…

How to quantify structural anomalies in fluids?
Yu. D. Fomin, B. A. Klumov, V. N. Ryzhov +1
Some fluids are known to behave anomalously. The so-called structural anomaly which means that the fluid becomes less structures under isothermal compression is among the most freq…
Dynamic transition in supercritical iron
