Fractal dimension and the counting rule of the Goldstone modes
Abstract It is argued that there are a set of orthonormal basis states, which appear as highly degenerate ground states arising from spontaneous symmetry breaking with a type-B Goldstone mode, and they are scale-invariant, with a salient feature that the entanglement entropy S (n) scales logarithmically with the block size …
