Asymptotic freedom, lost: Complex conformal field theory in the two-dimensional O(N>2) nonlinear sigma model and its realization in Heisenberg spin chainsThe two-dimensional O(N) nonlinear sigma model (NLSM) is asymptotically free for N>2: it exhibits neither a nontrivial fixed point nor spontaneous symmetry-breaking. Here we show that a…Christopher Yang, Thomas Scaffidi·Apr 2, 2026SaveLearn
