报告摘要

We used time- and angle-resolved photoemission (trARPES) to measure the non-equilibrium electronic states of Bi2Sr2CaCu2O8 high temperature superconductor. Detailed temperature and pump fluence dependent measurements were taken on these samples to study the temperature scales in cuprate, giving a phase diagram from the view of the non-equilibrium study. These results indicate that trARPES is a powerful tool in probing the quantum phase transitions in materials.
