Fig. 5. (Color online) The $P-\delta V_{\rm Reg}$ diagram from the ``fidelity susceptibility" in $d=4$ and $Q=0.1$. The temperatures of the isotherms increase from bottom to top. The upper dotted (black) line corresponds to the ideal gas; we have one phase for $T > Tc$ and the critical isotherm $T = Tc=0.44$ is denoted by the dashed (red) line. The lower (blue) solid lines correspond to temperatures smaller than the critical one $T <Tc$.
