Electron conductance and many-body marker of a cavity-embedded topological one-dimensional chain

DP Nguyen, G Arwas, C Ciuti - Physical Review B, 2024 - APS
We investigate many-body topological and transport properties of a one-dimensional Su–
Schrieffer–Heeger (SSH) topological chain coupled to the quantum field of a cavity mode …
