Sensitive dependence on molecular interactions of length scales in sheared soft matter
journal contribution
posted on 2020-09-15, 10:35 authored by Alberto Scacchi, Marco MazzaMarco Mazza, Andrew ArcherAndrew ArcherThe structure and degree of order in soft matter and other materials is intimately connected to the nature of
the interactions between the particles. One important research goal is to find suitable control mechanisms, to
enhance or suppress different structures. Using dynamical density functional theory, we investigate the interplay
between external shear and the characteristic length scales in the interparticle correlations of a model system.
We show that shear can controllably change the characteristic length scale from one to another quite distinct
value. Moreover, with specific small changes in the form of the particle interactions, the applied shear can either
selectively enhance or suppress the different characteristic wavelengths of the system, thus showing how to
tune these. Our results suggest that the nonlinear response to flow can be harnessed to design different actively
responsive materials.
