文摘The van der Waals diameter of a silicon atom is 220 pm,more than three orders of magnitude smaller than the wavelength of visible light.It is a common belief that events on a picometer scale cannot significantly influence light with wavelengths thousands of times larger.However,rather than using conventional light,the recent works demonstrated that topologically structured light offers the possibility of metrology at subatomic scale.
