Ultrafast spectroscopy of quasiparticle dynamics in cuprate superconductors
Wei Li, Chunfeng Zhang, Xiaoyong Wang +2
Ultrafast pump-probe spectroscopy is a powerful tool to study the nonequilibrium dynamics in high-Tc cuprate superconductors. The photo-induced quasiparticle (QP) dynamics revealed…
Enhanced Hot-Carrier Luminescence in Multilayer Reduced Graphene Oxide Nanospheres
Qi Chen, Chunfeng Zhang, Fei Xue +7
We report a method to promote photoluminescence emission in graphene materials by enhancing carrier scattering instead of directly modifying band structure in multilayer reduced gr…
Orbital-Selective Mottness in KxFe2-ySe2 Superconductors Revealed by Pump-Probe Spectroscopy
Wei Li, Chunfeng Zhang, Shenghua Liu +5
We report transient optical signatures of the orbital-selective Mottness in superconducting KxFe2-ySe2 crystals by using dual-color pump-probe spectroscopy. Besides multi-exponenti…
Ultrafast pump-probe spectroscopic signatures of superconducting and pseudogap phases in YBa2Cu3O7-δ films
Chunfeng Zhang, Wei Li, B. Gray +6
Femtosecond pump-probe spectroscopy is applied to identify transient optical signatures of phase transitions in optimally doped YBa2Cu3O7-δ films. To elucidate the dynamics of supe…
