topological invariants from the Green's function diagonal zeros
Florian Simon, Corentin Morice
We investigate the relationship between the analytical properties of the Green's function and topological insulators, focusing on three-dimensional inversion-symmetr…

Quantized and nonquantized Hall response in topological Hatsugai-Kohmoto systems
Thibaut Desort, Mark O. Goerbig, Corentin Morice
We explore the robustness of Hall conductivity quantization in several insulating systems, exhibiting one scenario where the quantization is not preserved. Specifically, we apply t…
