Fig. 3: Kinetically arrested phase transition.
From: Probing the evolution of electronic phase-coexistence in complex systems by terahertz radiation

a, b Comparison of temperature-dependent resistivities obtained through dc transport and THz-TDS (at 1 THz). Arrows show heating and cooling sequences. The shaded region in THz conductivity shows kinetically arrested phase where the metallic phase reappears below TMI. The kinetically arrested phase is detectable at all the THz frequencies shown by the shaded region in c, d.
