  1. Fermi liquids vs non-Fermi liquids

  2. Canonical behavior of the specific heat W. H. Lien and N. E. Phillips, Phys. Rev. 118, 958 (1960)

  3. Less canonical behavior of C(T)—notice a pronounced Such a term, however, is still within the Fermi-liquid theory. G. Stewart, Rev. Mod. Phys. 56, 755 (1984)

  4. FL metals

  5. Unconventional (“bad”, “strange”, “strongly correlated”, “non-FL”) metals Sr2RuO4

  6. Anomalouslinear-in-T scaling of the resistivity in high-Tccuprated C. Proust et al. PRL 89, 147003 (2002)

  7. The most prominent “collolungo” symptom: linear scaling of the resistivity Bruin et al. Science 339, 804 (2013)

  8. One possible sources of the symptom: Quantum Critical Point Simplest case: Pomeranchuk (q=0) critical point between a “paramagnet” and a uniformly ordered phase Nicklas et al. ‘99 T PM FM Quantum Critical point control parameter
