Molecular-level relation between intra-particle glass transition temperature and stability of colloidal suspensions
C. Anzivino, A. Zaccone
In many colloidal suspensions, the dispersed colloidal particles are amorphous solids resulting from vitrification. A crucial open problem is understanding how colloidal stability…
General theory of the viscosity of liquids and solids from nonaffine particle motions

A new microscopic formula for the viscosity of liquids and solids is derived rigorously from a first-principles (microscopically reversible) Hamiltonian for particle-bath atomistic…

Sara Pelargonio, Alessio Zaccone
We provide a first-principles derivation of the Langevin equation with shear flow and its corresponding fluctuation-dissipation theorems. Shear flow of simple fluids has been widel…
Estimating random close packing in polydisperse and bidisperse hard spheres via an equilibrium model of crowding
Carmine Anzivino, Mathias Casiulis, Tom Zhang +3
We show that an analogy between crowding in fluid and jammed phases of hard spheres captures the density dependence of the kissing number for a family of numerically generated jamm…

An analytical derivation of the vibrational density of states (DOS) of liquids, and in particular of its characteristic linear in frequency low-energy regime, has always been elusi…
Explaining the specific heat of liquids based on instantaneous normal modes
Matteo Baggioli, Alessio Zaccone
The successful prediction of the specific heat of solids is a milestone in the kinetic theory of matter, due to Debye (1912). No such success, however, has ever been obtained for t…

Matteo Baggioli, Ivan Kriuchevskyi, Timothy W. Sirk +1
The microscopic mechanism by which amorphous solids yield plastically under an externally applied stress or deformation has remained elusive in spite of enormous research activity…
