Breakdown of the Stokes-Einstein relation in supercooled liquids
Dimitrov, Ventzislav Ivanov (Trans Tech Publications Ltd, 2004)Breakdown of the Einstein-Stokes relation in undercooled liquids is one of the unsolved problems in the theory of liquids. The self-diffusion coefficient follows the temperature dependence of the Einstein-Stokes equation ... -
Fluctuation theory of the liquid-glass transition
Dimitrov, Ventzislav Ivanov (Trans Tech Publications Ltd, 2004)The glassy state and the character of the liquid-glass transition from undercooled liquid to amorphous solid is one of the biggest challenges of our time. In spite of significant progress we still cannot explain accurately ... -
Interpretation of the glass transition temperature from the point of view of molecular mobility
Dimitrov, Ventzislav Ivanov (Springer, 2005)Glass transition has been one of the biggest challenges in condensed matter physics during the last century: in spite of significant progress we still cannot explain the sudden solidification of undercooled liquids on the ... -
The liquid–glass transition – is it a fourth order phase transition?
Dimitrov, Ventzislav Ivanov (Elsevier Science, 2005-09-01)The liquid-glass transition is analyzed using a theory of Brownian motion in liquids recently developed by the author. It is shown that if a liquid could be cooled in quasi-static process and still avoids crystallization ... -
A model of AlN layer formation during ion nitriding of Al
Dimitrov, Ventzislav Ivanov (Springer-Verlag, 2004-11)A diffusion model of AlN layer formation by ion nitriding of Al is proposed based on the analysis of atomic transport during the process. This model is reduced to the following. Implantation of N ions to the surface of the ... -
Theoretical calculation of the kinetic coefficient of normal crystal growth
Dimitrov, Ventzislav Ivanov (Trans Tech Publications Ltd, 2004)An expression for the velocity u of migration of a diffuse simple crystal-melt interface has been derived on the basis of the theory of atomic mobility in supercooled liquids: u = K-0 (T / T-m) DeltaT, where DeltaT = T-m ... -
Theory of fluidity of liquids, glass transition, and melting
Dimitrov, Ventzislav Ivanov (Elsevier B.V., 2006-03-01)This is a presentation of a rigorous theory of fluidity of liquids, glass transition and melting of solids in the frame of an asymmetric double well potential model. Potential wells are doubled time to time by the local ...
