Single-Domain Orbital Angular Momentum Mapping: Advancing Photoemission Dichroism to the Nanoscale

Abstract Circular dichroism in angle-resolved photoemission spectroscopy (CD-ARPES) is widely used to probe orbital angular momentum (OAM) and Berry-curvature-related phenomena in two-dimensional quantum materials. However, in many materials, conventional micron-scale measurement...
