Universal Charge and Spin Response in Optimally Doped AntiferromagnetsDOI: 10.1103/PhysRevLett.75.1340 Abstract: Charge and spin response in the planar $t-J$ model at finite temperatures are investigated numerically, in the regime corresponding to cuprates at intermediate doping. We show that the local spin correlation function is $T$-independent, leading to $\chi''(\omega
