The neutron instruments suite, installed at the spallation neutron source of the Materials and Life Science Experimental Facility (MLF) at the Japan Proton Accelerator Research Complex (J-PARC), is reviewed. MLF has 23 neutron beam ports and 21 instruments are in operation for user programs or are under commissioning. A unique and challenging instrumental suite in MLF has been realized via combination of a high-performance neutron source, optimized for neutron scattering, and unique instruments using cutting-edge technologies. All instruments are/will serve in world-leading investigations in a broad range of fields, from fundamental physics to industrial applications. In this review, overviews, characteristic features, and typical applications of the individual instruments are mentioned.

We describe the parallelization and performance evaluation of the simulation program for emission of terahertz electromagnetic wave from high-Tc cuprate superconductors, where high performance was achieved as a result of tuning on multi-core system. Firstly the simulation space was divided for parallel processing, where MPI communication was implemented. The divided simulation space was further assigned to processes on multi-processors. Secondly parallel performance on each processor was accelerated by multi-threads implemented by OpenMP with a ratio at the number of core's. We have evaluated the parallelized program on HA8000 cluster system at Information Technology Center of the University of Tokyo, and, thus, achieved high performance in the analysis of terahertz electromagnetic wave emission from superconductors.

Times Cited Count：3 Percentile：12.09(Physics, Condensed Matter)We succeeded in growing high-quality single crystals of a heavy electron compound YbCuSi. The electronic specific heat coefficient 
is determined to be 150 mJ/K
mol, which is consistent with the 
value of the electrical resistivity from Kadowaki-Woods relation. We succeeded in observing the de Haas-van Alphen (dHvA) oscillations. The dHvA frequencies and large cyclotron effective masses in YbCuSi are highly different from those in a non-4
reference compound YCuSi. From these dHvA results, the heavy electron state of YbCuSi is characterized by the large contribution of 4-electrons to the volume of the Fermi surface and also to the strong enhancement of effective mass caused by the spin fluctuations.
