Why conventional GITT fails; how to fix it
We explain why conventional GITT (Galvanostatic Intermittent Titration Technique) measurements do not work as intended.

T2 Resistivity in Perovskites
Elongated Fermi surfaces in perovskites like SrTiO3 explain the T2 resistivity, previously thought to be from electron-electron interactions/scattering.
