The war in Ukraine: Does physics have a future?
Autor: Yurij Holovatch, Alexander Kordyuk, Ihor Mryglod
Publikováno v: Europhysics News. 53:20-23
The war in Ukraine is still going on. The number of victims is increasing every day. Many research centers are destroyed, researchers are displaced, and the conditions and nature of work in almost all regions of Ukraine have undergone significant cha

COLLECTIVE AUTHORSHIP IN UKRAINIAN SCIENCE: MARGINAL EFFECT OR NEW PHENOMENON?
Autor: Ihor Mryglod, Olesya Mryglod
Publikováno v: Visnik Nacional'noi' academii' nauk Ukrai'ni. :34-48
One of the features of modern science is the formation of stable large collaborations of researchers working together within the projects that require the concentration of huge financial and human resources. Results of such common work are published

Comment on 'Collective modes and gapped momentum states in liquid Ga: Experiment, theory, and simulation'
Autor: Taras Bryk, Ihor Mryglod, Giancarlo Ruocco
Publikováno v: Physical Review B. 103
We show that the presented in Phys.Rev.B, v.101, 214312 (2020) theoretical expressions for longitudinal current spectral function $C^L(k,\omega)$ and dispersion of collective excitations are not correct. Indeed, they are not compatible with the conti

Comment on 'Universal effect of excitation dispersion on the heat capacity and gapped states in fluids'
Autor: Giancarlo Ruocco, Jean-François Wax, Taras Bryk, Ihor Mryglod, Noël Jakse
Publikováno v: Physical Review Letters
Physical Review Letters, American Physical Society, 2021, 126 (22), pp.229601. ⟨10.1103/PhysRevLett.126.229601⟩
We discuss the validity of recent results in [Phys. Rev. Lett. 125, 125501 (2020)] on an universal relation between the heat capacity and dispersions of collective excitations in liquids.

The "Frenkel line" (FL), the thermodynamic locus where the time for a particle to move by its size equals the shortest transverse oscillation period, has been proposed as a boundary between recently discovered liquid-like and gas-like regions in supe

A simple closure procedure for the study of velocity autocorrelation functions in fluids as a 'bridge' between different theoretical approaches
Autor: Ihor Mryglod, V. V. Ignatyuk, Taras Bryk
Publikováno v: The Journal of Chemical Physics
Velocity autocorrelation functions (VAF) of the fluids are studied on short- and long-time scales within a unified approach. This approach is based on an effective summation of the infinite continued fraction at a reasonable assumption about converge

Comment on 'Lagrangian formulation and symmetrical description of liquid dynamics'
Autor: A. Duviryak, Taras Bryk, Ihor Mryglod
Publikováno v: Physical review. E. 99(3-2)
Trachenko [Trachenko, Phys. Rev. E 96, 062134 (2017)2470-004510.1103/PhysRevE.96.062134] has argued for creating a Lagrangian formulation of liquid dynamics. This Comment shows that the proposed two-field Lagrangian does not describe dynamics of liqu

B/anno:2018/pagina_da:6120/pagina_a:6123/intervallo_pagine:6120–6123/volume:122
In a previous letter and other papers, we have interpreted the supercritical region of fluids as being parted into a gas-like and a liquid-like regimes. The boundary between these two distinct regions of the P-T phase diagram of substances is represe
