Extended Data Fig. 3: Heat Capacity Fits for Sommerfeld Coefficient of CeSiI.
From: Two-dimensional heavy fermions in the van der Waals metal CeSiI
C/T of CeSiI (red) and fitted model (black/grey) for 15 < T < 100 K. The Bethe Ansatz Sommerfeld and CEF contributions to the total model are shown by blue and green dashed curves, respectively. Grey lines are fits with \({\chi }^{2}\) > 0.01, and thick black lines are fits with \({\chi }^{2}\) < 0.01.
