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…
Ground-state fidelity in one-dimensional gapless model
Min-Fong Yang
A general relation between quantum phase transitions and the second derivative of the fidelity (or the "fidelity susceptibility") is proposed. The validity and the limitation of th…
Entanglement and Quantum Phase Transition Revisited
Min-Fong Yang
We show that, for an exactly solvable quantum spin model, a discontinuity in the first derivative of the ground state concurrence appears in the absence of quantum phase transition…
