Uncovering novel phase structures in $$\Box ^k$$ □k scalar theories with the renormalization group
Abstract We present a detailed version of our recent work on the RG approach to multicritical scalar theories with higher derivative kinetic term $$\phi (-\Box )^k\phi $$ ϕ(-□)kϕ and upper critical dimension $$d_c = 2nk/(n-1)$$ dc=2nk/(n-1) . Depending on whether the numbers k and n have a common di...
