Spin g-factor due to electronic interactions in graphene

Spin g-factor due to electronic interactions in graphene The gyromagnetic factor is an important physical quantity relating the magnetic-dipole moment of a particle to its spin. The electron spin g-factor in vacuo is one of the best model-based theoretical predictions ever made, showing agreement with the measured value up to ten parts per trillion [J. Schwinger, Phys. Rev. 73, 416 (1948)PHRVAO0031-899X10.1103/PhysRev.73.416; R. S. Van Dyck, Jr. , Phys. Rev. Lett. 59, 26 (1987)PRLTAO0031-900710.1103/PhysRevLett.59.26; D. Hanneke , Phys. Rev.

However, for electrons in a material the g-factor is modified with respect to its value in vacuo because of environment interactions. Here, we show how interaction effects lead to the spin g-factor correction in graphene by considering the full electromagnetic interaction in the framework of pseudo-QED [A. Kovner , Phys. Rev.
