Universal finite-size effects in the viscoelasticity of confined amorphous systems
A. E. Phillips, M. Baggioli, T. W. Sirk +2
We present a theory of viscoelasticity of amorphous media, which takes into account the effects of confinement along one of three spatial dimensions. The framework is based on the…
Vibrational density of states of amorphous solids with long-ranged power-law correlated disorder in elasticity
Bingyu Cui, Alessio Zaccone
A theory of vibrational excitations based on power-law spatial correlations in the elastic constants (or equivalently in the internal stress) is derived, in order to determine the…
Plasmon energy losses in shear bands of metallic glass
Maximilian Grove, Martin Peterlechner, Harald Rösner +3
Shear bands resulting from plastic deformation in cold-rolled AlYFe metallic glass were observed to display alternating density changes along their propagation d…
Slow stretched-exponential and fast compressed-exponential relaxation from local event dynamics
K. Trachenko, A. Zaccone
We propose an atomistic model for correlated particle dynamics in liquids and glasses predicting both slow stretched-exponential relaxation (SER) and fast compressed-exponential re…
Unexpected thermo-elastic effects in liquid glycerol by mechanical deformation
Eni Kume, Alessio Zaccone, Laurence Noirez
It is commonly accepted that shear waves do not propagate in a liquid medium. The shear wave energy is supposed to dissipate nearly instantaneously. This statement originates from…
A new paradigm for the low-T glassy-like thermal properties of solids
Matteo Baggioli, Alessio Zaccone
Glasses and disordered materials are known to display anomalous features in the density of states, in the specific heat and in thermal transport. Nevertheless, in recent years, the…
Nonequilibrium master kinetic equation modelling of colloidal gelation
Joep Rouwhorst, Peter Schall, Christopher Ness +2
We present a detailed study of the kinetic cluster growth process during gelation of weakly attractive colloidal particles by means of experiments on critical Casimir attractive co…
Predictive model of polymer reaction kinetics and coagulation behavior in seeded emulsion co- and ter-polymerizations
Luca Banetta, Giuseppe Storti, George Hoogard +2
A mathematical model to describe the emulsion polymerization kinetics of co- and ter-polymerizations is developed. The model is based on the classical Smith-Ewart (SE) equations, w…
Atomic-scale expressions for viscosity and fragile-strong behavior in metal alloys based on the Zwanzig-Mountain formula
Giovanni Chevallard, Konrad Samwer, Alessio Zaccone
We combine the shoving model of -dependent viscosity of supercooled liquids with the Zwanzig-Mountain formula for the high-frequency shear modulus, using the of MD simula…
Scaling up the lattice dynamics of amorphous materials by orders of magnitude
Ivan Kriuchevskyi, Vladimir V. Palyulin, Rico Milkus +3
We generalise the non-affine theory of viscoelasticity for use with large, well-sampled systems of arbitrary chemical complexity. Having in mind predictions of mechanical and vibra…
Nonequilibrium continuous phase transition in colloidal gelation with short-range attraction
Joep Rouwhorst, Christopher Ness, Simeon Stoyanov +2
The dynamical arrest of attractive colloidal particles into out-of-equilibrium structures, known as gelation, is central to biophysics, materials science, nanotechnology, and food…
Theory of pressure-induced rejuvenation and strain-hardening in metallic glasses
Anh D. Phan, Alessio Zaccone, Vu D. Lam +1
We theoretically investigate high-pressure effects on the atomic dynamics of metallic glasses. The theory predicts compression-induced rejuvenation and the resulting strain hardeni…
Explaining the low-frequency shear elasticity of confined liquids
Alessio Zaccone, Kostya Trachenko
Experimental observations of unexpected shear rigidity in confined liquids, on very low frequency scales on the order of 0.01-0.1 Hz, call into question our basic understanding of…
Anharmonic theory of superconductivity in the high-pressure materials
Chandan Setty, Matteo Baggioli, Alessio Zaccone
Electron-phonon superconductors at high pressures have displayed the highest values of critical superconducting temperature on record, now rapidly approaching room temperatur…

The pair correlation function of charge stabilized colloidal particles under strongly sheared conditions is studied using the analytical intermediate asymptotics method recently de…
Physics of Phonon-Polaritons in Amorphous Materials
Luigi Casella, Matteo Baggioli, Tatsuya Mori +1
The nature of bosonic excitations in disordered materials has remained elusive due to the difficulties in defining key concepts such as quasi-particles in the presence of disorder.…
Secondary relaxation in the terahertz range in 2-adamantanone from theory and experiments
Bingyu Cui, Jonathan F. Gebbia, Michela Romanini +5
We applied the recently developed Generalized Langevin Equation (GLE) approach for dielectric response of liquids and glasses to link the vibrational density of states (VDOS) to th…
Relaxation and vibrational properties in metal alloys and other disordered systems

The relaxation dynamics and the vibrational spectra of amorphous solids, such as metal alloys, have been intensely investigated as well separated topics in the past. The aim of thi…
Anharmonic phonon damping enhances the of BCS-type superconductors

A theory of superconductivity is presented where the effect of anharmonicity, as entailed in the acoustic, or optical, phonon damping, is explicitly considered in the pairing mecha…
Effective Theory of Superconductivity in Strongly-Coupled Amorphous Materials
Matteo Baggioli, Chandan Setty, Alessio Zaccone
A theory of phonon-mediated superconductivity in strong-coupling amorphous materials is developed based on an effective description of structural disorder and its effect on the vib…
