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…
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…
Adam-Gibbs model in the density scaling regime and its implications for the configurational entropy scaling
Elzbieta Masiewicz, Andrzej Grzybowski, Katarzyna Grzybowska +3
To solve a long-standing problem of condensed matter physics with determining a proper description of the thermodynamic evolution of the time scale of molecular dynamics near the g…
Role of entropy in the thermodynamic evolution of the time scale of molecular dynamics near the glass transition
K. Grzybowska, A. Grzybowski, S. Pawlus +2
In this Letter, we investigate how changes in the system entropy influence the characteristic time scale of the system molecular dynamics near the glass transition. Independently o…
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…
Scaling of Volumetric Data in Model Systems Based on the Lennard-Jones Potential
Andrzej Grzybowski, Kajetan Koperwas, Marian Paluch
The crucial problem for better understanding the nature of glass transition and related relaxation phenomena is to find proper interrelations between molecular dynamics and thermod…
Beyond power-law density scaling: Theory, Simulation, and Experiment
Lasse Bøhling, Trond S. Ingebrigtsen, A. Grzybowski +3
Supercooled liquids are characterized by relaxation times that increase dramatically by cooling or compression. Many liquids have been shown to obey power-law density scaling, acco…
