Abstract We reconsider the complete solution of the linear TBA equation describing the energy density of finite density states in the O(N) nonlinear sigma models by the Wiener-Hopf method. We keep all perturbative and non-perturbative contributions and introduce a running coupling in terms of which all asymptotic series appearing in the problem can be represented as pure power series ... https://www.pomyslnaszycie.com/white-and-green-bulletin-board-border-simply-boho-schoolgirl-style-on-sale/
