Quantum Fisher information in a strange metal
Fig. 4, panel (b)
Quantum Monte Carlo QFI density $f^{\Psi}_{\mathrm{Q}}$ of the composite fermion against temperature $T$ at $J_k = 2.0$, $L = 18$, for $q = 2.0$, 0.4, 0.7 and $1.1q_{\mathrm{F}}$ with $q_{\mathrm{F}} = \pi/2$. Below the dotted line ($T = 0.08$, shaded in the print) finite-size effects set in. The print puts the $f^{\Psi}_{\mathrm{Q}}$ axis on the right.
