Multiband topological heterojunctions on the surface nanoscale axial photonics platform

Abstract Analogue Hamiltonian simulation (AHS) in photonic systems can be an enticing alternative to direct experimental study of complex Hamiltonian systems, leading to the emergence of the field of topological photonics. In this work, we leverage the ultra-low loss operation an...

Testing electron–photon exchange–correlation functional performance for many-electron systems under weak and strong light–matter coupling

We present results for a photon-free exchange–correlation functional within the local density approximation (pxcLDA) for quantum electrodynamics density functional theory (QEDFT), which efficiently describes the electron density of many-electron systems across weak to strong ligh...
