Electronic orders on the kagome lattice at the lower Van Hove filling
Electronic orders on the kagome lattice at the lower Van Hove filling
The effects of optical bond phonons coupled to electrons in two-dimensional lattices have attracted much interest recently, with the hope to explore unconventional superconducting mechanism and pairing symmetries. Here we conduct a systematic investigation of such phonon modes in the kagome lattice at and around the upper van Hove filling, …
