Extended defects in hard disk system and melting criteria
M. V. Kondrin, Y. B. Lebed, V. V. Brazhkin
The hard sphere model is widely used in description of fluids and solid media as a zero approximation to real systems. Despite the uniqueness of the model, few analytical results a…
The precision of molecular dynamics simulations and what we can learn from it?
M. V. Kondrin, Y. B. Lebed
We have investigated by molecular dynamics method the influence of a finite number of particles used in computer simulations on fluctuations of thermodynamic properties. As a case…
Phenomenological model of supercooled liquid as a possible resolution of the Kauzmann paradox
M. V. Kondrin, Y. B. Lebed, A. A. Pronin +1
The diverging relaxation time in approaching hypothetical ideal glass transition is a subject of hot debate. In the current paper we demonstrate, how diverging relaxation time and…
