Resolving the phase of a Dirac topological state via interferometric photoemission
Shiri Gvishi, Ittai Sidilkover, Yun Yen +10
The electronic wavefunction is at the heart of physical phenomena, defining the frontiers of quantum materials research. While the amplitude of the electron wavefunction in crystal…
Strongly-coupled hybrid lattice-plasmons in layered cuprates
Ke-Jun Xu, Nathan Giles-Donovan, Stefano Agrestini +11
Metallic systems with delocalized valence electrons host collective charge density oscillations known as plasmons. On the other hand, conventional insulators do not have free elect…
High-speed antiferromagnetic domain walls driven by coherent spin waves
Kyle L. Seyler, Hantao Zhang, Daniel Van Beveren +4
The ability to rapidly manipulate domain walls (DWs) in magnetic materials is key to developing novel high-speed spintronic memory and computing devices. Antiferromagnetic (AFM) ma…
Reexamining Circular Dichroism in Photoemission From a Topological Insulator
Ittai Sidilkover, Yun Yen, Sunil Wilfred D'Souza +10
The orbital angular momentum (OAM) of electron states is an essential ingredient for topological and quantum geometric quantities in solids. For example, Dirac surface states with…
