  The temperature-dependent evolution pattern of 5f electrons helps to
elucidate the long-standing itinerant-localized dual nature in plutonium-based
compounds. In this work, we investigate the correlated electronic states of
PuIn3 dependence on temperature by using a combination of the density
functional theory and the dynamical mean-field theory. Not only the
experimental photoemission spectroscopy is correctly reproduced, but also a
possible hidden 5f itinerant-localized crossover is identified. Moreover, it is
found that the quasiparticle multiplets from the many-body transitions
gradually enhance with decreasing temperature, accompanied by the
hybridizations with 5f electrons and conduction bands. The temperature-induced
variation of Fermi surface topology suggests a possible electronic Lifshitz
transition and the onset of magnetic order at low temperature. Finally, the
ubiquitous existence orbital selective 5f electron correlation is also
discovered in PuIn3. These illuminating results shall enrich the understanding
on Pu-based compounds and serve as critical predictions for ongoing
experimental research.
