  Title Equilibrium and symmetries of altitudinal magnetic rotors on a circle Type
  Year 2022 Publication Chaos Abbreviated Journal Chaos  
  Volume 32 Issue 12 Pages 123120  
  Keywords ARTIFICIAL SPIN ICE; DYNAMICS  
  Abstract Macroscopic magnets can easily be manipulated and positioned so that interactions between themselves and with external fields induce interesting dynamics and equilibrium configurations. In this work, we use rotating magnets positioned in a line or at the vertices of a regular polygon. The rotation planes of the magnets can be modified at will. The rich structure of stable and unstable configurations is dictated by symmetry and the side of the polygon. We show that both symmetric solutions and their symmetry-breaking bifurcations can be explained with group theory. Our results suggest that the predicted magnetic textures should emerge at any length scale as long as the interaction is polar, and the system is endowed with the same symmetries.

  Title Timescales in the thermal dynamics of magnetic dipolar clusters Type
  Year 2020 Publication Physical Review B Abbreviated Journal Phys. Rev. B  
  Volume 102 Issue 21 Pages 214442  
  Keywords ARTIFICIAL SPIN ICE; RELAXATION; FRACTIONALIZATION; FRUSTRATION; GLASSES; PHYSICS; PHASE; MODEL  
  Abstract The collective behavior of thermally active structures offers clues on the emergent degrees of freedom and the physical mechanisms that determine the low-energy state of a variety of systems. Here, the thermally active dynamics of magnetic dipoles at square plaquettes is modeled in terms of Brownian oscillators in contact with a heat bath. Solution of the Langevin equation for a set of interacting x-y dipoles allows the identification of the timescales and correlation length that reveal how interactions, temperature, damping, and inertia may determine the frequency modes of edge and bulk magnetic mesospins in artificial dipolar systems.
