Magnetoelectric polarizability: A microscopic perspective
Perry T. Mahon, J. E. Sipe
We extend a field theoretic approach for the investigation of the electronic charge-current density response of crystalline systems to arbitrary applied electromagnetic fields. The…

Microscopic polarization and magnetization fields in extended systems
Perry T. Mahon, Rodrigo A. Muniz, J. E. Sipe
We introduce microscopic polarization and magnetization fields at each site of an extended system, as well as free charge and current density fields associated with charge movement…

Quantum Interference Control of Localized Carrier Distributions in the Brillouin Zone
Perry T. Mahon, Rodrigo A. Muniz, J. E. Sipe
Using transition-metal dichalcogenides as an example, we show that the quantum interference arising in two- and three-photon absorption processes can lead to controllable, highly l…
