Caption

Composition-dependent ARPES intensity maps measured for Eu(Ga,Al)4. Red, blue, and green lines are guides for the eyes to trace the experimental Fermi surfaces h1, e2, and e1, respectively. The change in the Fermi surface (i.e., the appearance/disappearance of e1 Fermi surface) between EuGa4 and Eu(Ga0.62Al0.38)4 signifies a Lifshitz transition.
