Exact Strongly Coupled Fixed Point in $g\varphi^4$ Theory

Euro. Phys. Lett. 115, 27005 (2016) We show explicitly how a strongly coupled fixed point can be constructed in scalar $g\varphi^4$ theory from the solutions to a non-linear eigenvalue problem. The fixed point exists only for $d< 4$, is unstable and characterized by $\nu=2/d$ (correlation length...
