Angle-resolved photoemission spectroscopy (ARPES), with its exceptional sensitivity to both
the binding energy and the momentum of valence electrons in solids, provides unparalleled …

Free-electron lasers and high-harmonic-generation table-top systems are new sources of
extreme-ultraviolet to hard X-ray photons, providing ultrashort pulses that are intense …

Dirac fermions with highly dispersive linear bands,–are usually considered weakly
correlated due to the relatively large bandwidths (W) compared to Coulomb interactions (U) …

Screening, a ubiquitous phenomenon associated with the shielding of electric fields by
surrounding charges, has been widely adopted as a means to modify a material's properties …

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 …

Ultrafast experiments using sub-picosecond pulses of light are poised to play an important
role in the study and use of topological materials and, particularly, of the three-dimensional …

In this paper, we propose an energy functional at the level of DFT+ U+ V that allows us to
compute self-consistently the values of the onsite interaction, Hubbard U and Hund J, as …

Comprehending far-from-equilibrium many-body interactions is one of the major goals of
current ultrafast condensed matter physics research. Here, a particularly interesting but …

Metals are canonical plasmonic media at infrared and optical wavelengths, allowing one to
guide and manipulate light at the nanoscale. A special form of optical waveguiding is …
