Organic molecules are found everywhere and play an important role in almost all
biogeochemical processes occurring on the surface of the Earth (Aiken et al. 1985; Thurman …

We present a fully analytical implementation of the core–valence separation (CVS) scheme
for the equation-of-motion (EOM) coupled-cluster singles and doubles (CCSD) method for …

This article reviews the current status of inner-shell spectroscopies of free atoms and
molecules using high-resolution soft-x-ray monochromators installed in the soft-x-ray …

X-ray free-electron lasers (FELs) produce femtosecond x-ray pulses with unprecedented
intensities that are uniquely suited for studying many phenomena in atomic, molecular, and …

FlexPES is a soft X-ray beamline on the 1.5 GeV storage ring at MAX IV Laboratory,
Sweden, providing horizontally polarized radiation in the 40–1500 eV photon energy range …

Based on an asymmetric Lanczos-chain subspace algorithm, damped coupled cluster linear
response functions have been implemented for the hierarchy of coupled cluster (CC) models …

FinEstBeAMS (Finnish–Estonian Beamline for Atmospheric and Materials Sciences) is a
multidisciplinary beamline constructed at the 1.5 GeV storage ring of the MAX IV synchrotron …

A damped-response formalism in the GW approximation to the Bethe–Salpeter equation
(BSE) is presented and implemented. It is based on a quasirelativistic two-component (2c) …

We show that high fluence, high-intensity x-ray pulses from the world's first hard x-ray free-
electron laser produce nonlinear phenomena that differ dramatically from the linear x-ray …

The new beamline ALOISA, now operational at the Elettra Synchrotron, is designed for
surface studies by means of several experimental techniques: surface x-ray diffraction and …
