Metastable winding-number random-walk conjecture for the periodic XY chain
Metastable random-walk conjecture. (i) The metastable time satisfies τ(N)=C(JN,σN)eJN/σN2−logN\tau^{(N)}=C(J_N,\sigma_N)e^{J_N/\sigma_N^2-\log N}τ(N)=C(JN,σN)eJN/σN2−logN, where C(J,σ)C(J,\sigma)C(J,σ) is polynomial in JJJ and σ\sigmaσ. (…
