Internal structure of fluctuating Cooper pairs

ABSTRACT In order to obtain information about the internal structure of fluctuating Cooper pairs in the pseudogap state and below the transition temperature of high Tc superconductors, we solve the Bethe-Salpeter equation for the two-electron propagator in ...

Development of a novel drug delivery system based on polymeric, thermoresponsive, hydrogel nanoparticles

Carrier-mediated drug delivery has emerged as a powerful methodology for the treatment of various pathologies. The therapeutic index of traditional and novel drugs is enhanced via the increase of specificity due to targeting of drugs to a particular tissue ...

Dynamical arrest in dense short-ranged attractive colloids

Giuseppe Foffi, Francesco Sciortino

We study thermodynamic and dynamic properties of model colloidal systems interacting with a hard core repulsion and a short-range attraction, and provide an overall picture of their phase diagrams which shows a very rich phenomenology. We focus on the slow ...

Aging in short-ranged attractive colloids: A numerical study

Giuseppe Foffi, Francesco Sciortino

The aging dynamics in a model for dense simple liquids, in which particles interact through a hard-core repulsion complemented by a short-ranged attractive potential, of the kind found in colloidal suspensions, was studied. Kinetically arrested disordered ...

Interactions in systems with short-range attractions and applications to protein crystallisation

Giuseppe Foffi

The problem of phase behaviour of solutions of globular proteins is approached by means of a Hard Core Yukawa fluid model with short-ranged attractions. We have determined the phase behaviour of this model system for different well widths, using a variety ...

Star polymers: A study of the structural arrest in the presence of attractive interactions

Giuseppe Foffi

The structural arrest and the dynamics in star polymer solutions in the presence of attractive forces between microparticles were studied. The effect of the interplay between attractive interactions of different range and ultrasoft core repulsion, on the d ...

Activated Bond-Breaking Processes Preempt the Observation of a Sharp Glass-Glass Transition in Dense Short-Ranged Attractive Colloids

Giuseppe Foffi, Francesco Sciortino

We study—using molecular dynamics simulations—the temperature dependence of the dynamics in a dense short-ranged attractive colloidal glass to find evidence of the kinetic glass-glass transition predicted by the ideal mode coupling theory. According to the ...

Phase equilibria and glass transition in colloidal systems with short-ranged attractive interactions: Application to protein crystallization

Giuseppe Foffi, Francesco Sciortino

We have studied a model of a complex fluid consisting of particles interacting through a hard-core and short-range attractive potential of both Yukawa and square-well form. Using a hybrid method, including a self-consistent and quite accurate approximation ...

Ideal glass in attractive systems with different potentials

Giuseppe Foffi, Francesco Sciortino

We discuss the ideal glass transition for two types of potential model of attractive colloidal systems, i.e. the square-well system and the Yukawa hard-sphere fluid. We use the framework of the ideal mode-coupling theory and we mostly focus our attention o ...

Mode-coupling theory of colloids with short-range attractions

Giuseppe Foffi, Francesco Sciortino

Within the framework of the mode-coupling theory of super-cooled liquids, we investigate new phenomena in colloidal systems on approach to their glass transitions. When the inter-particle potential contains an attractive part, besides the usual repulsive h ...
