We study model protein solutions and colloidal suspensions in the temperature range whereupon the nature of the system changes from a homogeneous fluid to a cluster fluid. It is commonly assumed - as deduced by the behavior of the structural correlations - that this microphase separation sets as a continuous process. We challenge such assumption and demonstrate that the entropy shows a discontinuous behavior across a well-defined temperature threshold, providing a neat signature of the modifications occurring in the fluid. All predictions, obtained in the framework of a refined theory of the liquid state, are systematically assessed against extensive Monte Carlo simulations. We emphasize the broad generality of our conclusions, and the importance of accurate theoretical treatments to characterize the thermodynamic properties of soft materials.
Using our generalized Fick-Jacobs approach [Martens et al., PRL 110, 010601 (2013); Martens et al., Eur. Phys. J. Spec. Topics 222, 2453-2463 (2013)] and extensive Brownian dynamics simulations, we study particle transport through three-dimensional p
The aim of this focus letter is to present a comprehensive classification of the main entropic forms introduced in the last fifty years in the framework of statistical physics and information theory. Most of them can be grouped into three families, c
In this paper, we proved that by choosing the proper variational function and variables, the variational approach proposed by M. Doi in soft matter physics was equivalent to the Conservation-Dissipation Formalism. To illustrate the correspondence bet
A polymer chain pinned in space exerts a fluctuating force on the pin point in thermal equilibrium. The average of such fluctuating force is well understood from statistical mechanics as an entropic force, but little is known about the underlying for
The dynamics of dissipative soft-sphere gases obeys Newtons equation of motion which are commonly solved numerically by (force-based) Molecular Dynamics schemes. With the assumption of instantaneous, pairwise collisions, the simulation can be acceler
