Distinct amplitude mode dynamics upon resonant and off-resonant excitation across the charge density wave energy gap in LaTe3 investigated by time- and angle-resolved photoemission spectroscopy
Kecheng Liu, Takeshi Suzuki, Yigui Zhong +8
Non-equilibrium states generated by ultrafast laser pulses are characterized by specific phenomena that are not accessible in static measurements. Previous time- and angle-resolved…
Unveiling van Hove singularity modulation and fluctuated charge order in kagome superconductor via time-resolved ARPES
Yigui Zhong, Takeshi Suzuki, Hongxiong Liu +10
Kagome superconductor CsV3Sb5, which exhibits intertwined unconventional charge density wave (CDW) and superconductivity, has garnered significant attention recently. Despite exten…
Time- and angle-resolved photoemission spectroscopy with wavelength-tunable pump and extreme ultraviolet probe enabled by twin synchronized amplifiers
Takeshi Suzuki, Yigui Zhong, Kecheng Liu +3
We describe a setup for time- and angle-resolved photoemission spectroscopy with wavelength-tunable excitation and extreme ultraviolet probe. It is enabled by using the 10 kHz twin…
