Since the first demonstration of the generation of attosecond pulses (1 as= 10− 18 s) in the
extreme-ultraviolet spectral region, several measurement techniques have been introduced …

The development of femtosecond lasers brought entirely new possibilities into the practice of
timeresolved spectroscopy, for both UV-vis and IR-Raman spectroscopies. In addition, it has …

Comprehensive knowledge of the dynamic behaviour of electrons in condensed-matter
systems is pertinent to the development of many modern technologies, such as …

We present the advances in x-ray femtosecond pulse generation and the most recent
discoveries in the field of ultrashort (femtosecond) x-ray science. Nowadays x-rays show …

The significant progress in angle-resolved photoemission spectroscopy (ARPES) in last
three decades has elevated it from a traditional band mapping tool to a precise probe of …

In the last decade, there has been a proliferation of laser sources for time-and angle-
resolved photoemission spectroscopy (TR-ARPES), building on the proven capability of this …

We report the first observation of the laser-assisted photoelectric effect from a solid surface.
By illuminating a Pt (111) sample simultaneously with ultrashort 1.6 eV and 42 eV pulses …

Solid-state photoemission spectroscopy relies to a large part on pulsed photon sources:
third-generation synchrotron-radiation sources and ultrafast laser systems in particular …

The dissociation of excited state Br 2 is probed with the novel technique of ultrafast soft x-ray
photoelectron spectroscopy. Excited Br 2 molecules are prepared in the dissociative Π u 1 …

Techniques in time-and angle-resolved photoemission spectroscopy have facilitated a
number of recent advances in the study of quantum materials. We review developments in …
