Development of Yb-based Magnetic Refrigerants for Cryogenic Temperature near Absolute Zero

We have focused on Ytterbium(Yb)-based compounds to develop new magnetic refrigeration materials.

A new efficient scheme for producing low energy positron pulses with a SiC remoderator

By introducing another positron accumulator with a longer confinement time after the present setup, the higher intensity pulsed positron beams will be available

Laboratory Accelerator Physics: Design study of large-scale particle accelerators using a tabletop experimental simulator of rel

This new experimental technique revealed the dangerous parameter ranges where serious beam loss may occur due to resonant instability.

Novel multipolar ordering in a magnetically ordered state

Our experimental and calculated results revealed that a novel multipolar ordering occurs in a magnetically ordered state in the rare-earth compound ErNiAl.

Direct evaluation of measurement uncertainties by feedback compensation of decoherence

It is shown that the precision of a measurement outcome can be evaluated by compensating the effects of fluctuations in a weak interaction with a quantum probe before the measurement.

Uncertainty limits of the information exchange between a quantum system and an external meter

The trade-off between resolution and uncertainty is determined completely by the quantum mechanical relation between sensitivity and uncertainty in the meter system.
