Times Cited Count:0 Percentile:0(Chemistry, Physical)Hydrostatic and chemical pressure are efficient stimuli to alter the crystal structure and are commonly used for tuning electronic and magnetic properties in materials science. However, chemical pressure is difficult to quantify and a clear correspondence between these two types of pressure is still lacking. Here, we study intermetallic candidates for a permanent magnet with a negative thermal expansion (NTE). Based on in situ synchrotron X-ray diffraction, negative chemical pressure is revealed in HoFe on Al doping and quantitatively evaluated by using temperature and pressure dependence of unit cell volume. A combination of magnetization and neutron diffraction measurements also allowed one to compare the effect of chemical pressure on magnetic ordering with that of hydrostatic pressure. Intriguingly, pressure can be used to control suppression and enhancement of NTE. Electronic structure calculations indicate that pressure affected the top of the majority band with respect to the Fermi level, which has implications for the magnetic stability, which in turn plays a critical role in modulating magnetism and NTE. This work presents a good example of understanding the effect of pressure and utilizing it to control properties of functional materials.

Times Cited Count:12 Percentile:80.28(Astronomy & Astrophysics)The isospin violating decays of are revisited in a coupled-channel effective field theory. In a cutoff-independent formalism, we relate the coupling constants of with the two channels to the molecular wave function. The isospin violating decays of are obtained by two equivalent approaches, which amend some deficiencies about this issue in literature. In the quantum field theory approach, the isospin violating decays arise from the coupling constants of to two di-meson channels. In the quantum mechanics approach, the isospin violating is attributed to wave functions at the origin. We bridge the isospin violating decays of to its inner structure. Our results show that the proportion of the neutral channel in is over 80%. As a by-product, we find that the strong decay width and radiative decay width are about 30 keV and 10 keV, respectively, for the binding energy from -300 keV to -50 keV.

We include the possible violations of heavy quark spin symmetry and SU(3) flavor symmetry in a comprehensive approach. Our results show that the decay rates can be used to judge whether these resonances can be different states or not.

Our results show that the decay width of is the largest one, which is just the experimental observation channel. Our theoretical total strong and radiative widths are in favor of the as a dominated bound state. Our calculation is cutoff-independent and without prior isospin assignment. The absolute partial widths and ratios of the different decay channels can be used to test the structure of state when the updated experimental results are available.

The entry distribution method, which can determine the excitation energy at which fission starts to dominate the decay process, was applied to No. The fission barrier of No was found to be 6.6 MeV at zero spin, indicating that the No is strongly stabilized by the nuclear shell effects.

Experimental results are consistent with calculations from a combined density functional theory and dynamical mean field theory, and suggest that the decreased average pnictogen height in BaFe(AsP) reduces the strength of electron correlations and increases the effective bandwidth of magnetic excitation.

Precise measurements of branching ratios in the band confirm a clean 9/2[734]7/2[624] for the isomer, validating the systematics of K = 8 two-quasineutron isomers observed in even-, = 150 isotones. These isomers around the deformed shell gap at = 152 provide critical benchmarks for theoretical predictions of single-particle energies in this gateway region to superheavy nuclei.
