Fig. 2: Pressure cell and magneto resistivity results.
From: Tuning the BCS-BEC crossover of electron-hole pairing with pressure

a Photo of the pressure cell of external diameter 11.8 mm used in the pulsed-magnet. b Photo of a Kish graphite sample in the pressure cell. The pressure was determined in situ by the superconducting temperature transition of tin. c–h Field dependence of ρxx up to 60 T at various temperatures and for different pressures. Curves are shifted for clarity. The onset transition (α) and the re-entrant transition (\(\alpha ^{\prime}\)) of the first dome are indicated with black solid squares and red empty circles. The Shubnikov-de Haas oscillations at low-field are also observed at low temperatures (see Supplementary Note 2). The α and \(\alpha ^{\prime}\) are shifting to higher field after applied pressure. Under 1.12 Gpa, the \(\alpha ^{\prime}\) shifts beyond 60 T. Note c is the data without gasket and d–h are the ones with gasket.
