PANDA method: We have recently proposed a method called Pulse Analysis by Delayed Absorption (PANDA). The main merit of the PANDA method is that it can be used as an attosecond pulse characterization method that is free from atomic latency effects, such as scattering phase shifts and long-lived atomic resonances. We also propose that combining the PANDA method with angle-resolved photoelectron detection should allow for experimental measurements of attosecond delays in photoionization from bound wave packets on the order of tens of attoseconds. Works about the PANDA method: →Eliminating the dipole phase in attosecond pulse characterization using Rydberg wave packets Regular article in Physical Review A (2016) →Tutorial: Pulse Analysis by Delayed Absorption from a coherently excited atom Selected as a featured article in APL Photonics by American Institute of Physics (2018)					Schematic picture of the PANDA technique (click to enlarge).
Attosecond delays in photoionization: Great advances in experimental physics are being made using attosecond pulses of XUV radiation, where it is possible to initiate and control photoelectrons from atoms in real time. The typical duration of these pulses are 100 as (10^-16 s), which is comparable to the typical electronic obital motion in atoms. A natural question then arises: Is it possible to use these attosecond pulses to measure the time it takes for a photoelectron to be ionized? This is a fascinating question because it is well-known from quantum theory that time is not a direct observable quantity. Currently, my aim is to investigate what temporal aspects of photoionization can be measured in these state-of-art experiments by considering diagrammatic many-body perturbation theory.
