Ground-state Riemannian metric, cyclic quantum distance, and the quantum criticality in an inhomogeneous Ising spin chain

Yu-Quan Ma, Deng-Shan Wang, Ya-Jiang Hao +2

We investigate the ground-state Riemannian metric and the cyclic quantum distance of an inhomogeneous quantum Ising spin-1/2 chain in a transverse field. This model can be diagonal…
