Abstract
We report the explicit solution for the vacuum state of the two-dimensional Principal Chiral Model at large- for an arbitrary set of chemical potentials and any interaction strength, a unique result of such kind for an asymptotically free QFT. The solution matches one-loop perturbative calculation at weak coupling, and in the opposite strong-coupling regime exhibits an emergent spacial dimension from the continuum limit of the Dynkin diagram.
