From: Finite-temperature scaling of trace distance discord near criticality in spin diamond structure

(a)
and (b) its first-derivative
as a function of parameters Δ, respectively, around the critical line Δ − 2h + 3 = 0. (c) The peak position Δm can be regarded as a pseudo-critical point which shifts with temperature T following relation
in approaching to the critical point Δc. This character implies Δm → Δc as T → 0. (d) The maximal value of
at the pseudocritical point Δm as a function of T. The scaling behavior is very different from the counterpart in the quantum criticality from ENQ to UFI.
