Boundary conditions and universal finite-size scaling for the hierarchical $|\phi {|}^4$ model in dimensions 4 and higher

Emmanuel Michta, Jiwoon Park, Gordon Slade

We analyse and clarify the finite-size scaling of the weakly-coupled hierarchical $n$-component $|\phi {|}^4$ model for all integers $n\ge 1$ in all dimensions $d\ge 4$, for both free a…
