Ultrafast optical and far-infrared quasiparticle dynamics in correlated electron materials

Abstract

We review the application of ultrafast optical spectroscopy in the study of correlated electron materials. The emphasis is on all-optical pump–probe and optical pump–far-infrared probe experiments on (a) colossal-magnetoresistance manganites and (b) high-temperature superconductors. The experimental techniques are discussed followed by a brief review of ultrafast electron dynamics in conventional wide-band metals which serves as a starting point in understanding the dynamics in more complex metallic systems. In the half-metallic manganites, the quasiparticle dynamics in the ferromagnetic metallic state can be understood in terms of a dynamic transfer of spectral weight which is influenced by the lattice and spin degrees of freedom. For the high-temperature superconductors, ultrafast quasiparticle dynamics are sensitive to the order parameter and superconducting pair recovery occurs on a picosecond timescale. These results show that, in general, ultrafast optical spectroscopy provides a sensitive method to probe the dynamics of quasiparticles at the Fermi level.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
