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 …

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 …

The optical properties of graphene are made unique by the linear band structure and the
vanishing density of states at the Dirac point. It has been proposed that even in the absence …

Upon excitation with an intense laser pulse, a symmetry-broken ground state can undergo a
non-equilibrium phase transition through pathways different from those in thermal …

The ultrafast dynamics of excited carriers in graphene is closely linked to the Dirac spectrum
and plays a central role for many electronic and optoelectronic applications. Harvesting …

Ultrafast electronic relaxation of nucleobases from 1ππ* states to the ground state (S0) is
considered essential for the photostability of DNA. However, transient absorption …

High harmonic generation of ultrafast laser pulses can be used to perform angle-resolved
photoemission spectroscopy (ARPES) to map the electronic band structure of materials with …

We demonstrate a novel flat-field, dual-optic imaging EUV—soft X-ray spectrometer and
monochromator that attains an unprecedented throughput efficiency exceeding 60% by …

Direct and inverse Auger scattering are amongst the primary processes that mediate the
thermalization of hot carriers in semiconductors. These two processes involve the …

The dynamics of excited electrons and holes in single layer (SL) MoS2 have so far been
difficult to disentangle from the excitons that dominate the optical response of this material …
