Numerical study of magnetic excitations probed by photon spectroscopies in families of high-temperature superconductors

ORAL

Abstract

Magnetic excitation in high-temperature superconductors has been a topic of cutting edge research for many years. In photon spectroscopies, single- and two-magnon excitations can be created and measured efficiently using techniques such as resonant inelastic x-ray scattering and optical Raman scattering. We present numerical studies of the magnetic excitations for different families of high-temperature superconductors, including both copper and iron based superconductors. These magnetic excitations and their dispersions provide important information in understanding the magnetic properties of these materials.
