Iron antimonide (FeSb_{2}) with peculiar colossal thermopower of about −45 mV/K at 10 K is a mysterious material, and a unified microscopic description of this phenomenon is far from being achieved. Combining angle-resolved photoemission spectrosco

We compare the trends on the strength of electronic correlations across the different phases of elemental Pu focusing on its site and orbital dependence, using a combination of density functional theory (DFT) and dynamical mean-field theory (DMFT) ca

The iron antimonide FeSb$_2$ possesses an extraordinarily high thermoelectric power factor at low temperature, making it a leading candidate for cryogenic thermoelectric cooling devices. However, the origin of this unusual behavior is controversial,

We investigate the electronic structure of the highly anisotropic $\ensuremath{\beta}$ phase of metallic plutonium, within the combination of density functional theory and dynamical mean field theory. Its crystal structure gives rise to site and orbi

Here, we use angle-resolved photoemission spectroscopy to study superconductivity that emerges in two extreme cases, from a Fermi-liquid phase (LiFeAs) and an incoherent bad-metal phase (${\mathrm{FeTe}}_{0.55}{\mathrm{Se}}_{0.45}$). We find that alt

We report a theoretical investigation aiming at the prediction of graphene-like carbon nitride structures. Using a combination of model and ab initio calculations, we search among hundreds of thousands of CxNy structures in a wide (x, y) compositiona

We investigate, from first principles calculations, the magnetic properties of planar carbon nitride structures with the lowest formation energies within twenty eight distinct stoichiometries and porosities. Surprisingly, we find that 3/4 of the low-
