Fig. 3: phase diagram of graphite under pressure.
From: Tuning the BCS-BEC crossover of electron-hole pairing with pressure
a–f T − B phase diagrams for H∥c axis at the pressure of 0, 0.12, 0.35, 0.72, 1.12, and 1.7 GPa. The dome is shifting to higher field under hydrostatic pressure. In contrast, the summit of the dome is independent of the pressure. The two solid circles in the b show the kinks in magnetoresistance. h–m Tvs1/B at different pressure. The solid lines are a fit of the low-field boundary of phase α using Eq. (1), see the text. g, n Pressure dependence of the parameters T* and B* deduced from the fits.
