Observation of a Warped Helical Spin Texture in Bi[subscript 2]Se[subscript 3] from Circular Dichroism Angle-Resolved Photoemission Spectroscopy

Observation of a Warped Helical Spin Texture in Bi[subscript 2]Se[subscript 3] from Circular Dichroism Angle-Resolved Photoemission Spectroscopy

A differential coupling of topological surface states to left- versus right-circularly polarized light is the basis of many optospintronics applications of topological insulators. Here we report direct evidence of circular dichroism from the surface states of Bi[subscript 2]Se[subscript 3] using las...
