A critical-amplitude relation for quantum transitions in one dimension

Naomichi Hatano, Yoshihiro Nishiyama, Masuo Suzuki

Research output: Contribution to journalArticlepeer-review


A universal critical-amplitude relation which holds for one-dimensional quantum ground-state transitions is proposed. Using this relation in numerical studies, the correlation exponent η can be explicitly determined only from the scaling fit of the off-critical energy gap above the ground state.
