ABSTRACT The physics of heavy‐ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non‐abelian field theory, while on the experimental side today's largest accelerators are needed to enable these studies.

Rejection-based sampling of inelastic neutron scattering [PDF]
Distributions of inelastically scattered neutrons can be quantum dynamically described by a scattering kernel. We present an accurate and computationally efficient rejection method for sampling a given scattering kernel of any isotropic material. The proposed method produces continuous neutron energy and angular distributions, typically using just a ...

Hydrogen can be added to a solid solution of rutile oxides (RuxTi1‐xO2 and IrxTi1‐xO2) at a concentration of 20–30 at% by exposing it to hydrogen at a temperature of 150–200°C. This has been shown to dramatically increase the catalytic activity of oxidation reactions, such as the combustion of propane (thermal catalysis) and the evolution of oxygen in ...

Probing photoinduced spin states in spin-crossover molecules with neutron scattering [PDF]
We report a neutron scattering investigation of the spin crossover compound \rm [Fe(ptz)6](BF4)2 which undergoes an abrupt thermal spin-transition from high-spin (HS) S=2 to low-spin (LS) S=0 around 135 K.

Measurement of Leading Neutron Production in Deep-Inelastic Scattering at HERA [PDF]
The production of leading neutrons, where the neutron carries a large fraction x_L of the incoming proton's longitudinal momentum, is studied in deep-inelastic positron-proton scattering at HERA. The data were taken with the H1 detector in the years 2006 and 2007 and correspond to an integrated luminosity of 122 pb^{-1}.

Comprehensive Analysis of Crystalline Hydrophobic Alkylated Poly(ethyleneimine)s
Polyethyleneimine (PEI) is a widely used polymer in catalysis, gas separation, water treatment, drug delivery, textiles, and paper production. Herein, we investigate the crystalline structure of hydrophobic PEIs, prepared via simple alkylation as previously reported, using powder X‐ray diffraction, small‐angle X‐ray scattering, thermogravimetric ...

Linear Response Theory and the Universal Nature of the Magnetic Excitation Spectrum of the Cuprates
Linear response theory, commonly known as the random phase approximation (RPA), predicts a rich magnetic excitation spectrum for d-wave superconductors.

Ba3Yb2Zn5O11 is exceptional among breathing pyrochlore compounds for being in the nearly-decoupled limit where inter-tetrahedron interactions are weak, hosting isolated clusters or molecular magnet-like tetrahedra of magnetic ytterbium (Yb3+) ions.
