Abstract Attosecond spectroscopy,,,,,–can resolve electronic processes directly in time, but a
movie-like space–time recording is impeded by the too long wavelength (~ 100 times larger …

Recent advances in the generation of well-characterized subfemtosecond laser pulses have
opened up unpredicted opportunities for the real-time observation of ultrafast electronic …

The roles of energy, momentum and orbital angular momentum conservation in high-
harmonic generation were studied in the past. Here, we explore the role of spin angular …

The tunnelling of a particle through a potential barrier is a key feature of quantum mechanics
that goes to the core of wave–particle duality. The phenomenon has no counterpart in …
