"enhancing circularly polarized light's quantum vacuum fluctuations in single direction achieving chirality without high magnetic fields/ external stimuli adversely affecting materials inside... photonic-crystal chiral cavity lightly doped with indium antimonide, using order magnitude lower magnetic field facilitating strong, long-lasting graphene-light interactions reshaping the vacuum, opening band gap that changes its topological properties/ turns it into insulator useful for building new types of quantum devices "
