 Abstract: We will show you the helical quantum states in topological insulator quantum dots, its magneto-spectrum and the AB effect. The new edge states appear and show a spin-angular momentum locking. More interestingly, these equal-spacing edge states provide us a way to realize high harmonic generation at weak light intensity.
