Symmetry, topology, and geometry: The many faces of the topological magnetoelectric effect
Perry T. Mahon, Chao Lei, Allan H. MacDonald
A delicate tension complicates the relationship between the topological magnetoelectric effect (TME) in three-dimensional (3D) topological insulators (TIs) and time-…
Polarization and orbital magnetization in Chern insulators: A microscopic perspective
Perry T. Mahon, Jason G. Kattan, J. E. Sipe
We derive macroscopic expressions for the polarization and orbital magnetization of a Chern insulator in its zero-temperature ground state using a previously developed formalism fo…
Electric polarization and magnetization in metals
Perry T. Mahon, J. E. Sipe
A feature of the "modern theory" is that electric polarization is not well-defined in a metallic ground state. A different approach invokes the general existence of a complete set…
From magnetoelectric response to optical activity
Perry T. Mahon, J. E. Sipe
We apply a microscopic theory of polarization and magnetization to crystalline insulators at zero temperature and consider the orbital electronic contribution of the linear respons…
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…
