FIG. 16: On the left: Thermopower [95] in K-doped FeAs2 indicating a possible T ln T electronic en trop y near the doping for highest T$_{c}$ , indicating possible quan tum-criticality; On the right: Re- sistivity [90] in Co-doped FeAs2 for various concentration, showing a possible linear in T resistivity near the doping of highest T$_{c}$ , indicating scattering from a singular fluctuations sp ectra consis- tent with that which gives T ln T for the electronic entropy. Both are charaterisitic of Marginal Fermi-liquids. the hole-doped compound. The thermopower measurements are consistent with an entropy ∝ T ln( T ) down to T$_{c}$ from an upper cut-off of about the room temperature in a region close to the highest T$_{c}$ . Similarly, the resistivity is linear in temperature down to T$_{c}$ in a similar region. Neither of these properties are characteristic of fluctuations around a Gaussian quantum critical point, especially in 3d systems [31]. More experiments are needed to investigate whether the Fe-Pnictides have the same class of quantum-criticality as the Cuprates and the heavy-fermions. Experiments which would be helpful are measurements of the Raman and inelastic neutron scattering spectra, measurements of single-particle scattering rates by ARPES measurements and of transport scattering rate through optical conductivity measurements. Also analysis of ARPES spectra in the superconducting and normal state following such experiments to decipher the spec- 51
