Description:
Author(s): Yao Heng Su, Bing-Quan Hu, Sheng-Hao Li, and Sam Young Cho Spontaneous symmetry breaking in quantum phase transitions leads to a system having degenerate ground states in its broken-symmetry phase. In order to detect all possible degenerate ground states for a broken-symmetry phase, we introduce a quantum fidelity defined as an overlap measurement between a... [Phys. Rev.
