Universality of $S U (\infty)$ relaxation dynamics for $S U (n_{f})$ -symmetric spin-models

Duff Neill, Hanqing Liu

Spin-models, where the $N$ spins interact pairwise with a $S U (n_{f})$ symmetry preserving hamiltonian, famously simplify in the large $n_{f}$ , $N$ limits, as derived by Sachdev and Ye…

Scattering Neutrinos, Spin Models, and Permutations

Duff Neill, Hanqing Liu, Joshua Martin +1

We consider a class of Heisenberg all-to-all coupled spin models inspired by neutrino interactions in a supernova with $N$ degrees of freedom. These models are characterized by a c…
