The frequency of electric currents associated with charge carriers moving in the electronic
bands of solids determines the speed limit of electronics and thereby that of information and …

An accurate analytic model describing the microscopic mechanism of high-harmonic
generation (HHG) in solids is derived. Extensive first-principles simulations within a time …

Real-time observation of ultrafast dynamics in the microcosm is a fundamental approach for
understanding the internal evolution of physical, chemical and biological systems. Tools for …

The availability of high-energy pulses with durations shorter than the period of their carrier
frequency (sub-cycle) will reveal new regimes of strong-field light–matter interactions …

High harmonic generation (HHG) with longitudinal optical orbital angular momentum has
attracted much attention over the past decade. Here, we present the first study on the HHG …

High-order-harmonic generation by a highly nonlinear interaction of infrared laser fields with
matter allows for the generation of attosecond pulses in the XUV spectral regime. This …

Attosecond science promises to reveal the most fundamental electronic dynamics occurring
in matter and it can develop further by meeting two linked technological goals related to high …

Measuring the field of visible light with high spatial resolution has been challenging, as
many established methods only detect a focus-averaged signal. Here, we introduce a near …

We generate attosecond pulse train (APT) in argon driven by the high repetition rate (HR)
laser of the extreme light infrastructure-attosecond light pulse source (ELI-ALPS), providing …
