Phase Diagram of Magnetization Reversal Processes in Nanorings
, 2009 We investigate magnetization reversal processes of magnetic nanorings. Using a recently developed efficient cartesian coordinates fast multipole method, magnetization switching phase diagrams are constructed for such structures. We find that the dominant

Fast integral equation methods for the Laplace-Beltrami equation on the sphere [PDF]
, 2013 Integral equation methods for solving the Laplace-Beltrami equation on the unit sphere in the presence of multiple "islands" are presented. The surface of the sphere is first mapped to a multiply-connected region in the complex plane via a stereographic ...

Building upon Fast Multipole Methods to Detect and Model Organizations
, 2009 Many models in natural and social sciences are comprised of sets of inter-acting entities whose intensity of interaction decreases with distance. This often leads to structures of interest in these models composed of dense packs of entities.

A Provably Fast Multipole Method
, 2006 The evaluation of potential or force fields in systems of N particles whose interactions are Coulombic or gravitational is very important for several applications in natural science, applied mathematics, and computer science. A naive direct calculation of the interactions needs Theta(N^2) time per time step which is inappropriate for large systems ...
