Chern insulator optics

Jason G. Kattan, J. E. Sipe

Chern insulators have optical properties that are strikingly different than ordinary chiral media. Unlike the natural optical activity of the latter, which is a finite-wavelength e…

Ferroelectric superconductivity in noncentrosymmetric metals

Jason G. Kattan, T. Pereg-Barnea

It has recently been shown in experiments that certain materials can display both superconductivity and ferroelectricity, contrary to a long-standing conjecture that these two phen…

A new perspective on the anomalous Hall effect

Jason G. Kattan, Matthew Albert, J. E. Sipe

We revisit the anomalous Hall effect in magnetic conductors, and its generalization to finite frequencies, using a formalism based on microscopic notions of polarization, magnetiza…

Linear response of the Chern insulator MnBiTe: A Wannier function approach

Matthew Albert, Javier Sivianes, Jason G. Kattan +2

Recent work demonstrated that in the long wavelength limit the linear response of a Chern insulator to finite-frequency electric fields is the sum of two terms: A general frequency…

Chern insulators in two and three dimensions: A global perspective

Jason G. Kattan, J. E. Sipe

We introduce a second-quantized field theory for Chern insulators in which the Hamiltonian features a static vector potential that has the periodicity of the crystal's lattice and…

Linear response of a Chern insulator to finite-frequency electric fields

Jason G. Kattan, Alistair H. Duff, J. E. Sipe

We derive the macroscopic charge and current densities of a Chern insulator initially occupying its electronic ground state as it responds to a finite-frequency electric field; we…

Multipolar quantum electrodynamics of localized charge-current distributions: Spectral theory and renormalization

Jason G. Kattan, J. E. Sipe

We formulate a non-relativistic quantum field theory to model interactions between quantized electromagnetic fields and localized charge-current distributions. The electronic degre…

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…
