Although valence electrons are clearly delocalized in molecular bonding frameworks,
chemists and physicists have long debated the question of whether the core vacancy …

We introduce a new distance-based measure for the nonclassicality of the states of a
bosonic field, which outperforms the existing such measures in several ways. We define for …

The emission of an Auger electron is the predominant relaxation mechanism of core-vacant
states in molecules composed of light nuclei. In this non-radiative decay process, one …

The core-level photoelectron spectra of N 2 molecules are observed at high energy
resolution, resolving the 1σ g and 1σ u components as well as the vibrational components in …

The quantum nature of the state of a bosonic quantum field may manifest itself in its
entanglement, coherence, or optical nonclassicality. Each of these distinct properties is …

Analyses of phenomena exhibiting finite-time decay of quantum entanglement have recently
attracted considerable attention. Such decay is often referred to as sudden vanishing (or …

A multichannel single center (MCSC) method for the theoretical description of the electron
continuum spectrum in molecules is reported. The method includes coupling between …

We introduce, for each state of a bosonic quantum field, its quadrature coherence scale
(QCS), a measure of the range of its quadrature coherences. Under coupling to a thermal …

We present a detailed account of existing theoretical methods specially designed to provide
vibrationally resolved photoionization cross sections of simple molecules within the Born …

We used cold target recoil ion momentum spectroscopy (COLTRIMS) to investigate the
decay of Ne 2 after K-shell photoionization. The breakup into Ne 1+/Ne 2+ shows …
