A local quantized marker for topological magnons from circular dichroism
Baptiste Bermond, Anaïs Defossez, Gregor Jotzu +1
The low-energy excitations of a spin system can display Bloch bands with non-trivial topological properties. While topological magnons can be identified through the detection of ch…

Circular Dichroism on the Edge of Quantum Hall Systems: From Many-Body Chern Number to Anisotropy Measurements
F. Nur Ünal, A. Nardin, N. Goldman
Quantum Hall states are characterized by a topological invariant, the many-body Chern number, which determines their quantized Hall conductivity. This invariant also emerges in cir…
