Renormalized Classical Theory of Quantum Magnets

sunnysuite/sunny.jl 8 Apr 2023

We derive a renormalized classical spin (RCS) theory for $S > 1/2$ quantum magnets by constraining a generalized classical theory that includes all multipolar fluctuations to a reduced CP$^1$ phase space of dipolar SU($2$) coherent states.
