z r ∆h(r), whereσ α r (α = x, y, z) is the Pauli operator on site r ∈ Ω N . While the previous works regarding the quantum quench focused only on the final state, we here study the quench susceptibility,which quantifies the difference of the expectation values of the k-component of magnetization,m k = arXiv:1911.02456v2 [cond-mat.stat-mech] 3 Dec 2019 in isolated quantum systems: Supplemental Material A.
