Ultrafast-ARPES
Ultrfast-ARPES, Tr-ARPES/TARPES, or pump-probe ARPES refers to pump probe photoemission experiments conducted with pulses from a laser typically of femtosecond duration. Some pump probe modalities nonetheless exist at synchrotrons, and CW experiments can indirectly access dynamics by measuring quasiparticle diffusion.
Tr-ARPES datasets can in principle have at least two additional degrees
of freedom, the excitation delay—referred to through PyARPES as
delay
—and the pump wavelength.

More details and analysis examples to come in the future.
