Exciton collective modes in a bilayer of axion insulator
Olivia Liebman, Jonathan B. Curtis, Emily Been +1
We investigate the emergence of an exciton condensate and associated collective modes in a bilayer configuration of , an antiferromagnetic topological ins…

Multiphoton Spectroscopy of a Dynamical Axion Insulator
Olivia Liebman, Jonathan Curtis, Ioannis Petrides +1
The unusual magnetoelectric transport present in Weyl semimetals and 3D topological insula- tors can be compactly understood as manifestations of a background axion field, which it…

Observation of the Axion quasiparticle in 2D MnBiTe
Jian-Xiang Qiu, Barun Ghosh, Jan Schütte-Engel +32
In 1978, Wilczek and Weinberg theoretically discovered a new boson-the Axion-which is the coherent oscillation of the field in QCD. Its existence can solve multiple fundamenta…
