Configurational entropy of self propelled glass formers

چکیده

The configurational entropy is an indispensable tool to describe super-cooled liquids near the glass transition. Its calculation requires enumeration of basins in potential energy landscape and when available, it reveals a direct connection with relaxation time liquid. While there are several reports on measurement passive liquids, very little understood about its role active which have propensity undergo transition at low temperatures. In this paper, we report careful model former where constituent units self propelled. We show that unlike anharmonic contribution these self-propelled can be same order as harmonic contribution, therefore must included entropy. Our extracted good agreement generalized Adam-Gibbs relation predicted by random first theory enabling us deduce scaling between point-to-set length scale systems. findings could great utility conventional systems such granules, Janus particles dense bacterial suspensions, mention few.

Configurational entropy of polar glass formers and the effect of electric field on glass transition.

A model of low-temperature polar liquids is constructed that accounts for the configurational heat capacity, entropy, and the effect of a strong electric field on the glass transition. The model is based on the Padé-truncated perturbation expansions of the liquid state theory. Depending on parameters, it accommodates an ideal glass transition of vanishing configurational entropy and its avoidan...

Configurational Entropy Revisited

1548 Journal of Chemical Education • Vol. 84 No. 9 September 2007 • www.JCE.DivCHED.org Entropy change is categorized in some prominent general chemistry textbooks as being either positional (configurational) or thermal. Positional entropy focuses on the number of positions in space that can be occupied by the molecules of a system. Then, to the extent that more positions exist after a process ...

Coarse-grained microscopic model of glass formers.

We introduce a coarse-grained model for atomic glass formers. Its elements are physically motivated local microscopic dynamical rules parameterized by observables. Results of the model are established and used to interpret the measured behaviors of supercooled fluids approaching glass transitions. The model predicts the presence of a crossover from hierarchical super-Arrhenius dynamics at short...

Configurational entropy of hard spheres

We numerically calculate the configurational entropy Sconf of a binary mixture of hard spheres, by using a perturbed Hamiltonian method trapping the system inside a given state, which requires less assumptions than the previous methods [R.J. Speedy, Mol. Phys. 95, 169 (1998)]. We find that Sconf is a decreasing function of packing fraction φ and extrapolates to zero at the Kauzmann packing frac...

Corresponding states of structural glass formers.

The variation with respect to temperature T of transport properties of 58 fragile structural glass-forming liquids (67 data sets in total) are analyzed and shown to exhibit a remarkable degree of universality. In particular, super-Arrhenius behaviors of all supercooled liquids appear to collapse to one parabola for which there is no singular behavior at any finite temperature. This behavior is ...
