The reconstruction of attosecond beating by interference of two-photon
transitions (RABBIT) is one of the most widely used techniques for resolving
ultrafast electronic dynamics in atomic and molecular systems. As it relies on
the interference of photo-electrons in vacuum, similar interference has never
been contemplated in the bulk of crystals. Here we show that the interference
of two-photon transitions can be recorded directly in the bulk of solids and
read out with standard angle-resolved photo-emission spectroscopy. The phase of
the RABBIT beating in the photoelectron spectra coming from the bulk of solids
is sensitive to the relative phase of the Berry connection between bands and it
experiences a shift of π as one of the quantum paths crosses a band. For
resonant interband transitions, the amplitude of the RABBIT oscillation decays
as the pump and probe pulses are separated in time due to electronic
decoherence, providing a simple interferometric method to extract dephasing
times
