Detection of weak magnetic fields by using electron spins has been paid attention to by many researchers.

Engineering circularly-polarized vacuum field by chiral photonic crystals and its application to control the light emission from semiconductor quantum dots

January 1, 2016

Satoshi Iwamoto, University of Tokyo

For realizing spin-photon quantum hybrid systems, it is crucial to explore technologies for generating circularly-polarized photons efficiently and for controlling the interaction between materials and circularly-polarized photons. The foundation of them is the concept of artificial manipulation of electromagnetic vacuum.
