Abbamonte We used low-energy, momentum-resolved inelastic electron scattering to study surface collective modes of the three-dimensional topological insulators Bi 2 Se 3 and Bi 0.5 Sb 1.5 Te 3 − x Se x . Our goal was to identify the “spin plasmon” predicted by Raghu and co-workers [ Phys. Rev. Lett. 104 , 116401 (2010)]. In… [Phys. Rev. Lett. 115, 257402] Published Tue Dec 15, 2015
