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 origin of the density scaling exponent for polyatomic molecules and the estimation of its value from the liquid structure
Filip Kaskosz, Kajetan Koperwas, Andrzej Grzybowski +1
In this article, we unravel the problem of interpreting the density scaling exponent for the polyatomic molecules representing the real van der Waals liquids. Our studies show that…
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…
On the breakdown of the simple Arrhenius law in the normal liquid state
Erik Thoms, Andrzej Grzybowski, Sebastian Pawlus +1
It is common practice to discuss the temperature effect on molecular dynamics of glass formers above the melting temperature in terms of the Arrhenius law. Using dielectric spectro…
In search of invariants for viscous liquids in the density scaling regime: Investigations of dynamic and thermodynamic moduli
Agnieszka Jedrzejowska, Andrzej Grzybowski, Marian Paluch
In this paper, we report on nontrivial results of our investigations of dynamic and thermodynamic moduli in search of invariants for viscous liquids in the density scaling regime b…
