Ubiquitous suppression of the nodal coherent spectral weight in Bi-based cuprates

Abstract: High-temperature superconducting cuprates exhibit an intriguing phenomenology for the low-energy elementary excitations. In particular, an unconventional temperature dependence of the coherent spectral weight (CSW) has been observed in the superconducting phase by angle-resolved photoemission spectroscopy (ARPES), both at the antinode where the d-wave paring gap is maximum, as well as along the gapless nodal direction. Here, we combine equilibrium and time-resolved ARPES to track the temperature-dependent melt… Show more

“…Hund metals with an orbital selective Mott phase, as proposed by Yi et al for certain iron chalcogenides [15], may show QP weights → 0 for orbitals that localize, while the weights of orbitals contributing to high temperature transport may well show the behavior uncovered here for Sr 2 RuO 4 . An important issue for future experimental work will be to investigate QP residues in Mott systems such as VO 2 and V 2 O 3 or doped iridates and cuprates [57,58].…”
