$\mu$SR study on noncentrosymmetric superconductor NbGe$_{\mathbf{2}}$

Autor: Jiao, J. C., Chen, K. W., Hillier, A. D., Ito, T. U., Higemoto, W., Li, Z., Lv, B. J., Xu, Z. -A., Shu, L.

We report a muon spin relaxation ($\mu$SR) study on polycrystalline noncentrosymmetric superconductor NbGe$_2$~with the superconducting transition temperature $T_c=2.0\sim2.1$~K. Zero-field $\mu$SR~experiment indicates the absence of spontaneous magn

Spontaneous magnetic field and disorder effects in BaPtAs_1-x_Sb_x_ with honeycomb network

Chiral superconductivity exhibits the formation of novel electron pairs that breaks the time-reversal symmetry and has been actively studied in various quantum materials in recent years. However, despite its potential to provide definitive informatio

Understanding muon diffusion in perovskite oxides below room temperature based on harmonic transition state theory

Autor: Ito, T. U., Higemoto, W., Shimomura, K.

Publikováno v: Phys. Rev. B 108, 224301 (2023)

In positive muon spin rotation and relaxation ($\mu^+$SR) spectroscopy, positive muons ($\mu^+$) implanted into solid oxides are conventionally treated as immobile spin-probes at interstitial sites below room temperature. This is because each $\mu^+$

Pole-fitting for complex functions: enhancing standard techniques by artificial-neural-network classifiers and regressors

Autor: Kaidisch, S., Hilger, T. U., Krassnigg, A., Lucha, W.

Publikováno v: Computer Physics Communications, Volume 295, 2024, 108998

Motivated by a use case in theoretical hadron physics, we revisit an application of a pole-sum fit to dressing functions of a confined quark propagator. More precisely, we investigate approaches to determine the number and positions of the singularit

Interplay of the Indian summer monsoon and intermonsoon precipitation in Sri Lanka due to ITCZ migration during the last 80000 years

Autor: P. N. Ranasinghe, K. A. Hughen, T. U. T. Wijewardhana, J. D. Ortiz, A. K. I. U. Kapuge, Kalpani M. Ratnayake, N. U. Nanayakkara, A. L. T. Hewawasam, Y. P. S. Siriwardana, S. Kodithuwakku

Publikováno v: Scientific Reports, Vol 14, Iss 1, Pp 1-14 (2024)

Abstract Precipitation variations in the tropical Indian Ocean region result from changes in the Indian Summer Monsoon (ISM), as well as convective and cyclonic rainfall. The relative roles of such forcing can be elucidated by constructing robust pal

Local electronic structure of interstitial hydrogen in MgH$_2$ inferred from muon study

Autor: Kadono, R., Hiraishi, M., Okabe, H., Koda, A., Ito, T. U.

Publikováno v: J. Phys.: Condens. Matter 35, 285503 (2023)

Magnesium hydride has great potential as a solid hydrogen (H) storage material because of its high H storage capacity of 7.6 wt%. However, its slow hydrogenation and dehydrogenation kinetics and the high temperature of 300 $^\circ$C required for deco

Scanning X-ray diffraction microscopy of a 6 GHz surface acoustic wave

Autor: Hanke, M., Ashurbekov, N., Zatterin, E., Msall, M. E., Hellemann, J., Santos, P. V., Schulli, T. U., Ludwig, S.

Publikováno v: Phys. Rev. Applied 19, 024038 (2023)

Surface acoustic waves at frequencies beyond a few GHz are promising components for quantum technology applications. Applying scanning X-ray diffraction microcopy we directly map the locally resolved components of the three-dimensional strain field g
