Time-resolved ARPES with fs-XUV radiation (KREIOS MM)
slower decay in the Σ valley (~1.3 ps) compared to the K valley (~0.69 ps), and measured intervalley scattering times of ~94 fs. Correlation-driven excitations in FePS₃ In Newton (1, 2, 2025) , we traced [...] sub-100 fs buildup and picosecond decay of d–d orbital excitations in the layered antiferromagnet FePS₃. The results disentangle spin-allowed and spin-forbidden pathways and reveal the interplay between local …
