‘The simplest model of a complex fluid’
by R.M.L. Evans,
School of Mathematics, University of Leeds.
Originally invented to describe magnetic materials, the classical XY model has the simplest interactions imaginable. Surprisingly, when subjected to counter-rotating boundaries, it exhibits the non-Newtonian flow regimes characteristic of soft matter. With an elaborate steady-state phase diagram but a very concise constitutive relation, it offers a paradigm for diverse non-equilibrium complex fluids.
