Abstract

A bulk crystal, as small as 0.5 mm in size, contains more than a quintillion atoms that behave collectively like a large-scale object. When such a crystal is disturbed by an outside influence, it quickly transitions into a new steady state after a brief transient phase known as relaxation. When this phase is the shortest in duration, the system can exhibit extreme sensitivity to even a tiny perturbation. Examining changes in relaxation in a bulk material could help engineer new sensors and rapid response devices. However, the transient response only lasts for a few picoseconds, making observation difficult. On page 1152 of this issue, J. Li et al. (1) report an experimental measurement of relaxation transition in a single-crystal europium monoxide (EuO). The achievement suggests a means to observe similar phase transition in other bulk crystalline materials.
