The state-dependent operator fidelity susceptibility (OFS), the leading-order term for slightly different operator parameters, is shown to have a nontrivial behavior when the environment is at critical points. Two different contributions to the OFS are id...<br/><br/>Xiao-Ming Lu, Zhe Sun, Xiaoguang Wang, Paolo Zanardi (2008) <i>Phys. Rev. A</i> 78: 3 <br/>
