RABBITT-HOP- new angles on an old bunny

The RABBITT technique (reconstruction of attosecond beating by interference of two photon transitions) is a widely used tool in attoscience useful both for the characterisation of ultrashort pulses, and as a stopwatch for ultrafast processes. Recently we have extended the RABBITT technique to enable several novel measurements, including the so-called 'partial-wave meter'– measuring the amplitude and phase of individual partial wave contributions in two-photon ionisation– and the untangling of the which-way interference in a RABBITT analogue of the double-slit experiment. In this talk I will give an overview of the R-matrix with time-dependence (RMT) method, show the results from these two studies, as weil as some (as-yet) unpublished results for what we are calling "RABBITT-HOP"- RABBITT with higher order processes.
