Opis:
A P-type icosahedral quasicrystal with a six-dimensional lattice parameter $a_{6D}$ = 7.411 Å is formed as an equilibrium phase in Au-Al-Tm alloy, of which composition was analyzed to be $Au_{46}Al_{38}Tm_{16}$ by electron probe microanalysis. This quasicrystal is observed as a predominant phase in both as-cast and $Au_{49}Al_{34}Tm_{17}$ alloys annealed at 910°C, and as one of main phases in the alloy slowly cooled from 1020°C. A 1/1 approximant, $Au_{48}Al_{38}Tm_{14}$, is also formed near the composition of the quasicrystal. This is a body-centered cubic structure (space group: Im3̅) with a lattice parameter a = 14.458 Å that is an isostructure to the recently reported 1/1 Tsai-type approximant in Au-Al-Yb. This approximant is characterized by disorderly arranged four Au-Al atoms centered at the Tsai-type cluster, presence of atoms at 8c site, and chemical ordering of Au and Al at sites forming a partial triacontahedron.

Opis:
The mixed-valence Au-Al-Yb quasicrystal exhibits unusual quantum criticality. Its crystalline approximant behaves like a conventional heavy fermion metal. Due to these novel features, they have attracted much attention recently. To examine the sample dependence of this new type of materials, we have prepared several samples and measured the electrical resistivity both at ambient and high pressures as well as the magnetic susceptibility at ambient pressure. The residual resistivity ratio of the quasicrystals is almost sample independent while the power law exponent n of the electrical resistivity varies from sample to sample. The effective magnetic moment $p_{eff}$ of the quasicrystals is also sample dependent, ranging from about 3.4 to 3.9 $μ_{B}$/Yb, and these values are all smaller than the free $Yb^{3+}$ ion value, confirming the mixed-valence nature. Although the magnitude of n and $p_{eff}$ is sample-dependent, the principal feature of the mixed-valence is confirmed in all the samples studied thus far. A combination of these results indicates correlation between n and $p_{eff}$, suggesting that the 4f electrons may contribute to a scattering mechanism of the conduction electrons. External pressure increases the magnitude of the electrical resistivity and decreases the index n of both the quasicrystal and the approximant. Up to the highest pressure measured in the present study no experimental evidence for a phase transition was found.

Opis:
The Electron-Ion Collider (EIC), a state-of-the-art facility for studying the strong force, is expected to begin commissioning its first experiments in 2028. This is an opportune time for artificial intelligence (AI) to be included from the start at this facility and in all phases that lead up to the experiments. The second annual workshop organized by the AI4EIC working group, which recently took place, centered on exploring all current and prospective application areas of AI for the EIC. This workshop is not only beneficial for the EIC, but also provides valuable insights for the newly established ePIC collaboration at EIC. This paper summarizes the different activities and R&D projects covered across the sessions of the workshop and provides an overview of the goals, approaches and strategies regarding AI/ML in the EIC community, as well as cutting-edge techniques currently studied in other experiments.

Opis:
Correlation between dislocation types in epitaxial 4H-SiC and etch pit types on the 4H-SiC wafer surface were investigated by etch pit method and transmission electron microscope. Shallow dislocation on the wafer was found to form round pit without core. The shallow dislocation was estimated half-loop type in wafer and this estimation explains that step-flow growth converts half-loop dislocation into complex dislocation composed by threading dislocation and basal plane dislocation.

Opis:
Radioactive tin beams were used to explore the flow observables under varying isospin asymmetries while maintaining a constant total charge. The rapidity dependence of directed flow (v$_{1}$) and elliptic flow (v$_{2}$) was studied for protons, deuterons, tritons, $^{3}$He, and $^{4}$He, produced in neutron-rich $^{132}$Sn + $^{124}$Sn and neutron-deficient $^{108}$Sn + $^{112}$Sn collisions at 270 MeV / nucleon. In general, heavier particles exhibited larger v$_{1}$ and v$_{2}$ values. The experimental data was used to test transport models which simulate heavy ion collisions. Specifically, comparisons were made with Antisymmetrized Molecular Dynamics (AMD) model calculations, which explicitly account for cluster correlations. Two types of momentum-dependent mean field potentials were tested. The results reveal that both v$_{1}$ and v$_{2}$ values are enhanced when the mean field incorporates stronger momentum dependence. In addition, v$_{2}$ exhibits larger sensitivity to symmetry energy than v$_{1}$ but the overall sensitivity to symmetry energy is low. In an attempt to describe the data, different parameter sets have been tried. Most describe either the hydrogen flow or helium flow reasonably well but none describes the flow of all particles simultaneously.

Opis:
The rapidity distributions of hydrogen isotopes emitted from central collisions of neutron-rich 132Sn+124Sn and neutron-deficient 108Sn+112Sn systems at 270 MeV/nucleon were investigated at RIKEN-RIBF. The data are compared with antisymmetrized molecular dynamics (AMD) calculations and the rapidity distributions can be reproduced after adjusting the in-medium nucleon-nucleon cross sections. The double ratios between the two reaction systems taken for the relative yields of deuteron to proton (d/p) and triton to proton (t/p) are further examined in the midrapidity domain, where the adjustments in the AMD calculations do not affect much on them. The d/p and t/p double ratios at midrapidity agree well with the ratio of the system neutron numbers and its squared value, respectively, and the rapidity dependence of these double ratios is consistent with a picture of partial mixing of colliding nuclei. By comparing with the AMD model which shows a strong symmetry energy dependence of the t/p double ratio, the experimental result in the midrapidity domain favors the calculation with a symmetry-energy slope parameter around L=46 MeV rather than L=108 MeV.
