Extended Data Fig. 4: Shubnikov-de-Haas measurements and fermiology analysis at D = 1.05 V/nm.

(A) raw quantum oscillation data which is used to compute the Fourier transform in panel C. The white arrows indicate electron like quantum oscillations associated with f3. (B) comparison of Rxx and inverse compressibility κ at zero magnetic field. (C) Fourier transform of the data in A for fields from 150 - 300 mT similar to main text Fig. 2b. The region of SC1,2 are indicated by the white dashed lines. As SC1 is not well formed and is barely visible in Rxx, one should confirm its location with the 2D resistance map in Fig. S10. Note: due to the higher field range used here compared to the main text, additional peaks associated with magnetic breakdown effects between different pockets of f4,5 are apparent. (D) Schematic of panel C with main frequencies extracted via Gaussian fits to the data (f3 is not well captured by fits and extracted manually here). Shaded areas represent error bars corresponding to the standard deviation of Gaussian fits to the peak frequencies The same phases as in the main text Fig. 2 are observed, most importantly showing the transition to the nematic N2,4 phase.
