Alpha-induced total reaction cross sections in the low-energy region below 400 MeV are investigated using an intranuclear cascade model based on the extended framework for nucleon- and deuteron-induced reactions. Experimental data for 
C, 
Si, 
Ca, and 
Pb targets are reproduced well by calculations performed with reasonable parameters close to those determined in other studies. It is shown that two effects, namely, discrete level constraint (DLC) and the Coulomb effect, provide important contributions that depend on the incident- energy and target. The DLC effect is limited to a narrow region of low-energy and is very important in light targets. The Coulomb effect is decisive on cross sections in Pb, while the DLC contribution for the heavy target is small. It is concluded that this trend in the contribution of both effects is consistent with proton- and deuteron-induced total reaction cross sections.

The gravitational form factors (GFFs) of pions are calculated from a top-down holographic quantum chromodynamics (QCD) approach with momentum transfer dependence for the first time. It is important because the GFFs of hadrons have information on the internal stress distribution that may provide insight into the mechanism of how QCD forms hadrons. The forward limit value of this GFFs, i.e. the D-term, was also obtained. Furthermore, in this approach, we observe the so-called glueball dominance, in which pions have gravitational interactions via infinite glueball spectra.

We investigate the thermodynamics and phase structure of 
Yang-Mills theory on 
in Euclidean spacetime in an effective-model approach. The model incorporates two Polyakov loops along two compactified directions as dynamical variables, and is constructed to reproduce thermodynamics on measured on the lattice. The model analysis indicates the existence of a novel first-order phase transition on in the deconfined phase, which terminates at critical points that should belong to the two-dimensional 
universality class. We argue that the interplay of the Polyakov loops induced by their cross term in the Polyakov-loop potential is responsible for the manifestation of the first-order transition.

Times Cited Count：0The -Mn phase exhibits a large anomalous Hall effect (AHE) in its pressure-induced weak ferromagnetic (WFM) state, despite its relatively small spontaneous magnetization of 0.02 
/Mn. To understand the underlying mechanism behind this AHE, we performed single crystal neutron diffraction measurements at 2.0 GPa to determine the magnetic structure of the WFM phase. Our investigation reveals a ferrimagnetic structure characterized by nearly collinear magnetic moments aligned along the [001] direction at sites I, II, III-1, and IV-1. In contrast, the small moments at sites III-2 and IV-2 lie within the (001) plane. The calculated net magnetization of this magnetic structure, (-0.020
0.005)/Mn atom, is in excellent agreement with the experimentally determined spontaneous magnetization. The observation of a magnetic reflection at 
= (0, 0, 0) satisfies a key condition for the emergence of the AHE.

Times Cited Count：0 Percentile：0.00(Materials Science, Multidisciplinary)The frustrated antiferromagnet CuFeO exhibits pressure-induced complex magnetic phase transitions from the commensurate collinear (CM1) phase to several incommensurate noncollinear phases. To study the effect of high pressure on magnetic interactions, we performed neutron diffraction and inelastic neutron scattering experiments under high-pressure conditions. With increasing pressure, the CM1 ground state becomes less stable against application of a magnetic field even below the critical pressure (
3 GPa), as proved by the significant reduction in the critical magnetic field from 
=7.5 T to 4.5 T at 2.1 GPa. Additionally, the energy gap in the spin-wave dispersion relation is reduced from 1.0 to 0.88 meV by the application of a pressure of = 2.1 GPa. Comparing the experimental results with spin-wave calculations revealed that the change in the spin-wave excitation can be explained by the reduction in either the uniaxial anisotropy term or the degree of separation in the nearest-neighbor exchange interactions.
