Micro-mechanical theory of shear yield stress for strongly flocculated colloidal gel

We derive a constitutive relation for shear yield stress of strongly aggregated colloidal gel as a function of interparticle potential, volume fraction, contact scale properties and gel microstructure.

Simple prescription for computing the nonrelativistic interparticle potential energy related to dual models

Following a procedure recently utilized by Accioly et al. to obtain the D-dimensional interparticle potential energy for electromagnetic models in the nonrelativistic limit, and relaxing the condition assumed by the authors concerning the conservation of the external current, the prescription found out by them is generalized so that dual models can also be contemplated. Specific models in which the interaction is mediated by a spin-0 particle described first by a vector field and then by a higher-derivative vector field, are analyzed. Systems mediated by spin-1 particles described, respectively, by symmetric rank-2 tensors, symmetric rank-2 tensors augmented by higher derivatives and antisymmetric rank-2 tensors, are considered as well.

The role of interparticle interaction and environmental coupling in a two-particle open quantum system

At t = 0, the magnitudes of the statistical correlation between the particles positions depends on the strength of the repulsive interparticle potential (green, strongest potential; red, weakest potential). As the bath is turned on, the relative magnitudes of the correlation are inverted.
