Pseudo-Hermitian physics from dynamically coupled macrospins
Peter Connick, Shane P. Kelly, Yaroslav Tserkovnyak
We consider two classical macrospins with dynamical (frequency-dependent) coupling, modeled by a generalized Landau-Lifshitz-Gilbert equation. We show that, in the absence of local…

An algorithm for computing root multiplicities in Kac-Moody algebras
Aidan Backus, Peter Connick, Joshua Lin
Root multiplicities encode information about the structure of Kac-Moody algebras, and appear in applications as far-reaching as string theory and the theory of modular functions. W…
