Fidelity and Quantum phase transition for the Heisenberg chain with the next-nearest-neighbor interaction

Shu Chen, Li Wang, Shi-Jian Gu +1

In this paper, we investigate the fidelity for the Heisenberg chain with the next-nearest-neighbor interaction (or the model) and analyze its connections with quantum pha…
