Fidelity approach to Gaussian transitions
Yu-Chin Tzeng, Hsiang-Hsuan Hung, Yung-Chung Chen +1
The fidelity approach to the Gaussian transitions in spin-one XXZ spin chains with three different values of Ising-like anisotropy lambda is analyzed by means of the density matrix…

Scaling Properties of Fidelity in Spin-one Anisotropic Model
Yu-Chin Tzeng, Min-Fong Yang
By means of the density matrix renormalization group technique, the scaling relation of the fidelity susceptibility proposed recently is verified for the spin-one XXZ spin chain wi…
