Partial Antiferromagnetic Helical Order in Fe $_{3}$ PO $_{4}$ O $_{3}$

C. L. Sarkis, M. J. Tarne, J. R. Neilson +4

Magnetic frustration in Fe $_{3}$ PO $_{4}$ O $_{3}$ has been shown to produce to an unusual magnetic state below T $_{N} = 163$ K, where incommensurate antiferromagnetic order is restricted to…

The persistent homology of cyclic graphs

Henry Adams, Ethan Coldren, Sean Willmot

We give an $O (n^{2} (k + lo g n))$ algorithm for computing the $k$ -dimensional persistent homology of a filtration of clique complexes of cyclic graphs on $n$ vertices. This is nearly q…
