The breakdown of the direct relation between the density scaling exponent and the intermolecular interaction potential for molecular systems with purely repulsive intermolecular forces
Filip Kaśkosz, Kajetan Koperwas, Andrzej Grzybowski +1
In this work, we question the generally accepted statement that the character of intermolecular interactions can be directly determined from the scaling exponent. Based on detailed…
The computational evidence for the crucial role of the dipole cross-correlations in the polar glass-forming liquids
Kajetan Koperwas, Marian Paluch
In this letter, we analyze the dipole-dipole correlations obtained from the molecular dynamics simulations for strongly- and weakly-polar model liquids. As a result, we found that…
Coupling between structural relaxation and diffusion in glass-forming liquids under pressure variation
Anh D. Phan, Kajetan Koperwas, Marian Paluch +1
We theoretically investigate structural relaxation and activated diffusion of glass-forming liquids at different pressures using both the Elastically Collective Nonlinear Langevin…
Virial-potential energy correlation and its relation to the density scaling for quasi-real model systems
K. Koperwas, A. Grzybowski, M. Paluch
In this letter, we examine the virial and the potential energy correlation for the quasi-real model system. This correlation constitutes the framework of the theory of the isomorph…
A pathway towards proper modeling of physical properties
K. Koperwas, A. Grzybowski, M. Paluch
Theoretical concepts in condensed matter physics are typically verified and also developed by exploiting computer simulations mostly in simple models. Predictions based on these us…
Equation of state in the generalized density scaling regime studied from ambient to ultra-high pressure conditions
Andrzej Grzybowski, Kajetan Koperwas, Marian Paluch
In this paper, based on the effective intermolecular potential with well separated density and configuration contributions and the definition of the isothermal bulk modulus, we der…
Dynamic heterogeneity of glass-forming liquids in the density scaling regime
Andrzej Grzybowski, Kajetan Koperwas, Karolina Kolodziejczyk +2
Recent analyses of high pressure measurement data suggest that the degree of the dynamic heterogeneity (χ_4)^max cannot be in general a single variable function of the structural r…
Activation Volume in the Density Scaling Regime: Equation of State and Its Test by Using Experimental and Simulation Data
Andrzej Grzybowski, Kajetan Koperwas, Alicja Swiety-Pospiech +2
In this paper, a formalism for the activation volume of glass forming materials is suggested. An isothermal equation of state for the activation volume is formulated, which is exte…
