Due to a beneficial balance of computational cost and accuracy, real-time time-dependent
density-functional theory has emerged as a promising first-principles framework to describe …

The property of a variable charge state makes ions unique to other types of radiation a
material surface can be exposed to. As a consequence of charge exchange between ions …

Matter at extreme temperatures and pressures—commonly known as warm dense matter
(WDM)—is ubiquitous throughout our Universe and occurs in astrophysical objects such as …

Real-time time-dependent density functional theory (TDDFT) is presently the most accurate
available method for computing electronic stop** powers from first principles. However …

We report a first-of-its-kind analysis on post-Trotter simulation of U (1), SU (2), and SU (3)
lattice gauge theories including fermions in arbitrary spatial dimension. We provide explicit …

The electronic stop** power and charge state of protons and helium ions irradiating iron
under both channeling and off-channeling geometries are studied by first-principles …

We use first-principles calculations to uncover and explain a new type of anomalous low-
velocity stop** effect in proton-irradiated graphene. We attribute a shoulder feature that …

Real-time time-dependent density functional theory (TDDFT) is widely considered to be the
most accurate available method for calculating electronic stop** powers from first …

Simulations and diagnostics of high-energy-density plasmas and warm dense matter rely on
models of material response properties, both static and dynamic (frequency-dependent) …

Highly energetic ions traversing a two-dimensional material such as graphene produce
strong electronic excitations. Electrons excited to energy states above the work function can …
