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 generation of extremely short isolated attosecond pulses requires both a broad spectral
bandwidth and control of the spectral phase. Rapid progress has been made in both …

Since 2001 and the first demonstrations of the feasibility of generating and measuring
attosecond light pulses, attosecond science has developed into a very active and quickly …

In this review, we will focus on the theoretical aspects in observing and controlling the
electronic dynamics in few-electron atoms and molecules by attosecond pulses in different …

The natural timescale for electron dynamics reaches down to the attosecond domain.
Following the discovery of attosecond laser pulses, about a decade ago, attosecond science …

An attosecond molecular interferometer is proposed by using a XUV–XUV pump-probe
scheme. The interferograms resulting in the photoelectron distributions enable the full …

Photoelectron interferometry with femtosecond and attosecond light pulses is a powerful
probe of the fast electron wave-packet dynamics, albeit it has practical limitations on the …

Ionisation with ultrashort pulses in the extreme ultraviolet (XUV) regime can be used to
prepare an ion in a superposition of spin–orbit substates. In this work, we study the …

We present an ultrafast quantum state holography scheme based on the interference of
photoelectron wave packets from multiphoton ionization (MPI) using shaper-generated …

We present quantum-beat spectroscopy of excited states of helium atoms populated
selectively with high-order-harmonic emission below the atomic ionization potential by …
