Theoretical insights into electronic nematic order, bond-charge orders, and plasmons in cuprate superconductors
Hiroyuki Yamase
Abstract:Journal of the Physical Society of JapanThe parent compound of high-T c cuprate superconductors is a Mott insulator described by the Heisenberg spin-spin interaction on a square lattice. With carrier doping, the charge degree of freedom becomes active and both spin and charge couple to each other, leading to very rich physics including high-T c superconductivity. In this article, we focus on the charge degree of freedom and review theoretical insights into the electronic nematic order, bond-charge orders, and … Show more
