Kondo hybridization and quantum criticality in $\beta$-YbAlB${}_4$ by laser-ARPES

C. Bareille, S. Suzuki, M. Nakayama +6

We report an angle-resolved photoemission (ARPES) study of $\beta$-YbAlB${}_4$, which is known to harbor unconventional quantum criticality (QC) without any tuning. We directly observe a…
