We review the many-body Green's function Bethe–Salpeter equation (BSE) formalism that is
rapidly gaining importance for the study of the optical properties of molecular organic …

We describe state of the art methods for the calculation of electronic excitations in solids and
molecules, based on many body perturbation theory, and we discuss some applications of …

Develo** nonflammable electrolytes with wide electrochemical windows is of great
importance for energy storage devices. Water-in-salt electrolytes (WiSE) have attracted great …

We present GW calculations of molecules, ordered and disordered solids and interfaces,
which employ an efficient contour deformation technique for frequency integration and do …

The position of electronic energy levels in a phase depends on the surface potentials at its
boundaries. Bringing two phases in contact at an interface will alter the surface potentials …

The photo-induced radiolysis of water is an elementary reaction in biology and chemistry,
forming solvated electrons, OH radicals, and hydronium cations on fast time scales. Here …

We describe an ab initio approach to compute the optical absorption spectra of molecules
and solids, which is suitable for the study of large systems and gives access to spectra within …

Deep inelastic neutron scattering measurements of water confined in nanoporous xerogel
powders, with average pore diameters of 24 and 82 Å⁠, have been carried out for pore …

Several chalcogenide alloys exhibit a pronounced contrast between the optical absorption
in the metastable rocksalt and in the amorphous phase. This phenomenon is the basis for …

Excitonic effects in optical spectra and electron-hole pair excitations are described by
solutions of the Bethe-Salpeter equation (BSE) that accounts for the Coulomb interaction of …
