comment Topological Charge. What is it Physically?
topological quasiparticle ie "domain-wall" in symmetry breaking phase are not stable. If we break the symmetry they will confine.

Thank you for fixing the answer!

comment Topological Charge. What is it Physically?
(1) In 1D Ising model with open boundary condition in the symmetry breaking phase, the first excited state is NOT just flipping a single spin on one edge. (2) What is "the topological quasiparticle in 1D Ising model"? Do mean domain-wall? (3) the two-fold ground-state degeneracy in 1D Ising model in the symmetry breaking phase come from symmetry breaking.

The full answer is too long to fit here. It needs a whole paper.
