The Fermi and Rashba energies of surface states in the ${\text{Bi}}_{x}{\text{Pb}}_{1\ensuremath{-}x}/\text{Ag}(111)$ alloy can be tuned simultaneously by changing the composition parameter $x$. We report on unconventional Fermi surface spin textures observed by spin and angle-resolved photoemission spectroscopy that are correlated with a topological transition of the Fermi surface occurring at …
