Collective Magnetic Excitations in a Photo-excited Electron-doped Cuprate Superconductor

Daniel Jost, Jiarui Li, Jordyn Hales +21

Elucidating the microscopic behavior of cuprates under ultrafast photoexcitation offers critical insights into their highly correlated out-of-equilibrium states. Although quasipart…

Reconstructing the wavefunction of magnetic topological insulators MnBi2Te4 and MnBi4Te7 using spin-resolved photoemission

Xue Han, Jason Qu, Hengxin Tan +7

Despite their importance for exotic quantum effects, the surface electronic structure of magnetic topological insulators MnBi2Te4 and MnBi4Te7 remains poorly understood. Using high…

Analysis methodology of coherent oscillations in time- and angle-resolved photoemission spectroscopy

Nicolas Gauthier, Hadas Soifer, Jonathan A. Sobota +5

Oscillatory signals from coherently excited phonons are regularly observed in ultrafast pump-probe experiments on condensed matter samples. Electron-phonon coupling implies that co…
