Fig. 4: Dynamical Planckian scaling plot.
From: Anisotropic non-Fermi liquid and dynamical Planckian scaling of a quasi-kagome Kondo lattice system
σin(ω) ⋅ Tα as a function of ℏω/kBT as shown in Eq. (1) for E∥a (a) and E∥c (b). The intrinsic heavy quasiparticles' σin(ω) spectra were obtained by subtracting the background spectra due to light quasiparticles and interband transitions from the original σ1(ω) spectra. The broad solid line in (a) indicates a guide to the eye to indicate the scaling. DPS requires α = 1, but different α values are adopted for E∥c in (b). The inset of (a) shows the standard deviation (SD) of \(\log [{\sigma }_{in}(\omega ){T}^{\alpha }]\) vs \(\log [\hslash \omega /{k}_{{\rm{B}}}T]\) from a straight line as a function of α.
