“…(2) k (τ ), calculated with Eq. ( 14), gives the standard RABBITT formula (18) where the oscillation phase corresponds to the difference between the phase of the adjacent harmonics ∆φ k = φ k+1 − φ k−1 , regardless the exact IR intensity and harmonic strength.…”

“…Alongside with attosecond streaking [1,2], in the recent years the reconstruction of attosecond beating by interference of two-photon transitions (RABBITT) [3,4] has established as a powerful technique capable to access electron dynamics [5,6] in atoms [7], molecules [8], liquids [9] and solids [10]. Pioneering experiments have shown the capability of this interferometric approach to resolve the ultrafast processes which unfold during photoemission [11,12], disclosing the effect of different kind of resonances [13][14][15][16][17][18][19], nuclear motion [20,21], local potential profile [22], spacial field distribution [23], continuumcontinuum transitions [24] and angular beatings [25,26].…”

Originally proposed for the temporal characterization of train of attosecond pulses, the reconstruction of attosecond beating by interference of two-photon transitions (RABBITT), has become a wide-spread, powerful technique, capable to capture ultrafast electron dynamics through an interferometric approach. Starting from the well-known strong-field approximation (SFA) description of a two-color photoelectron spectrum, here we develop a model that interprets a RABBITT trace as the interference of different Floquet ladder states generated in the continuum by a femtosecond infrared (IR) pulse after ionization by the attosecond radiation. In turn, this allowed us to develop an analytical model capable of predicting the amplitude and phase of the oscillating sidebands and mainbands while including the effect of non-standard interference paths and, in first approximation, of the finite IR pulse envelope. Our results thus suggest a way to extend the RABBITT model to higher intensities and beating frequencies, and disentangle different oscillating signals in a congested photoelectron spectrogram as the one associated with molecular targets.

“…These first pioneering experiments demonstrated the potential of the streaking spectroscopy which has been later used to study a variety of physical phenomena initiated by light in solids, like the intrinsic and extrinsic excitation of plasmons in Mg [221], the role of intra-atomic electron-electron interaction in WSe 2 [50] and the role of surface resonances in Mg(0001) [222]. Nevertheless, its application remains a formidable task because of the associated technical and theoretical complexity.…”

Attosecond spectroscopy for the investigation of ultrafast dynamics in atomic, molecular and solid-state physics

Since the ﬁrst demonstration of the generation of attosecond pulses (1 as = 10-18s) in the extreme-ultraviolet (XUV) spectral region, several measurement techniques have been introduced, at the beginning for the temporal characterization of the pulses, and immediately after for the investigation of electronic and nuclear ultrafast dynamics in atoms, molecules and solids with unprecedented temporal resolution. The attosecond spectroscopic tools established in the last two decades, together with the development of sophisticated theoretical methods for the interpretation of the experimental outcomes, allowed to unravel and investigate physical processes never observed before, such as the delay in photoemission from atoms and solids, the motion of electrons in molecules after prompt ionization which precede any notable nuclear motion, the temporal evolution of the tunneling process in dielectrics, and many others. This review focused on applications of attosecond techniques to the investigation of ultrafast processes in atoms, molecules and solids. Thanks to the introduction and ongoing developments of new spectroscopic techniques, the attosecond science is rapidly moving towards the investigation, understanding and control of coupled electron-nuclear dynamics in increasingly complex systems, with ever more accurate and complete investigation techniques. Here we will review the most common techniques presenting the latest results in atoms, molecules and solids.

“…It provides subcycle resolution of coherent energy transfer dynamics in solids, [6,7] precise timeresolved measurements of the photoelectric effect, [8][9][10] and real-time investigations of ultrafast many-body dynamics. [11][12][13][14][15][16] On the other hand, a tailored incident electric field can be used to control the current flow within an optoelectronic device in a transistor-like fashion, leading to PHz optical gates. [17,18] This concept naturally followed the notable progress of optical-field induced currents in dielectrics, which laid the foundation for ultrafast optoelectronic switching.…”

The emerging field of lightwave electronics is driving optoelectronic information processing beyond current classical limitations and has the potential to eventually reach petahertz frequencies. One of the major obstacles in reaching not only higher switching frequencies but also higher repetition rates with low‐power light sources is the efficiency of related devices. A device is presented based on a multilayered material that shows a 13‐fold enhancement in terms of converting light to electric current compared to bulk solids. Furthermore, the device exhibits an almost flat intensity response within its working range. The outstanding properties of engineered multilayered devices promise to push technology for lightwave electronics applications.
