The Quest for the Quark‐Gluon Plasma From the Perspective of Dynamical Models of Relativistic Heavy‐Ion Collisions

Astronomische Nachrichten, EarlyView.
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.

Neutron scattering as a probe of the Fe-pnicitide superconducting gap

, 2008
Inelastic neutron scattering provides a probe for studying the spin and momentum structure of the superconducting gap. Here, using a two-orbital model for the Fe-pnicitide superconductors and an RPA-BCS approximation for the dynamic spin susceptibility ...

Itinerant Spin Excitations in SrFe2As2 Measured by Inelastic Neutron Scattering [PDF]

, 2010
We report inelastic neutron scattering measurements of the magnetic excitations in SrFe2As2, the parent of a family of iron-based superconductors. The data extend throughout the Brillouin zone and up to energies of ~260meV.

Compression‐Induced Amorphization of ZIF‐62 Leading to Formation of Porous Glass: Overcoming the Limitations of Current Methods

Chemistry–Methods, EarlyView.
Nonhydrostatic compression in steps is applied to transform crystalline zeolitic imidazolate framework‐62 into glass at room temperature. This method overcomes the limitations of existing approaches. This research reveals the mechanism of this phase transformation, including modifications in porosity, using various techniques, particularly positron ...

Inelastic Scattering of Neutrons by Rotational Excitation [PDF]

Progress of Theoretical Physics, 1955
The collective nuclear model of A. Bohr is applied to the interpretation of inelastic scattering of neutrons, as was briefly described in our previous report6l. The present paper deals with the detailed theory of the inelastic scattering of neutrons by a direct excitation of the nuclear surface rctation, as well as by the resonance scattering via ...

Acoustic Nature of the Boson Peak in Vitreous Silica

, 1999
New temperature dependent inelastic x-ray (IXS) and Raman (RS) scattering data are compared to each other and with existing inelastic neutron scattering data in vitreous silica (v-SiO_2), in the 300 - 1775 K region.

Magnetic excitations in multiferroic LuMnO3 studied by inelastic neutron scattering [PDF]

, 2010
from inelastic neutron scattering, magnetization and thermal expansion mea-surements. We measured the magnon dispersion along the main symmetry directions and used thisdata to determine the principal exchange parameters from a spin-wave model.

Quantifying Molecular Properties of Hexagonal Water Clusters

ChemistryOpen, EarlyView.
Standard quantum chemical calculations on large hexagonal water clusters allow us to analyze the fundamental properties of ice‐Ih. Computed geometrical structure, energies, and vibrational spectra are astonishingly close to experimental data without the introduction of any external empirical parameters.

Phase transitions and spin dynamics of the quasi-one dimensional Ising-like antiferromagnet BaCo_{2}V_{2}O_{8} in a longitudinal magnetic field

Physical Review Research, 2023
By combining inelastic neutron scattering and numerical simulations, we study the quasi-one-dimensional Ising-like quantum antiferromagnet BaCo_{2}V_{2}O_{8} in a longitudinal magnetic field applied along the Ising anisotropy, which is also the chain ...
