Query: Nahm equations in supersymmetric mechanics   We elaborate on a novel model of N=4 supersymmetric mechanics with extra spin
variables. A dynamical linear (1,4,3) multiplet is coupled to a
"semi-dynamical" linear (3,4,1) multiplet representing spin degrees of freedom
in a Wess-Zumino action. The unique coupling of these two multiplets relates
the dynamical bosonic variable to an arbitrary harmonic function of the SU(2)
triplet of spin variables. As we prove at the classical and quantum level, N=4
supersymmetry is equivalent to the Nahm equations for the spin variables, with
the dynamical boson as evolution parameter. We treat in detail the one- and
two-monopole as well as some special multi-monopole configurations. While one
monopole exhibits superconformal OSp(4|2) symmetry and was worked out
previously, only N=4, d=1 Poincare supersymmetry survives for multi-monopole
configurations.
