The kilogram is the only SI base unit still defined by the material artifact. In order to redefine the unit based on the fundamental physical constant, the Avogadro constant has been determined by the X-ray crystal density method using a highly enriched ^<28>Si crystal. A review is given on the international effort to reduce the uncertainties in the lattice parameter, density, and molar mass measurements of the crystal, as well as recent results on the watt balance experiments.

Nothingness is not empty in physics. It stands for the vacuum state of quantum fields with spatially entangled zero-point fluctuation. The vacuum entanglement allows for quantum protocols which attain energy transportation using only local operations and classical communication in an operational meaning. Thus the protocol is referred to as quantum energy teleportation (QET). QET is expected to be implemented by using quantum Hall edge currents. QET also sheds new light on the information loss problem of black hole evaporation.

We present the Breit interaction effects on dielectronic recombination processes of highly charged heavy ions. Experimental results obtained by using the Tokyo electron beam ion trap clearly demonstrate state-selective strong Breit interaction effects, which notably enhance the resonance strength and dominate the angular distribution of emitted X-rays.

In uniform three dimensional magnets we had not expected to observe time variations of magnetic properties within an attainable time scale. Contrary to all expectations, a long-time variation of magnetic structure was observed in a non-diluted uniform magnet CeIr_3Si_2 by means of time-resolved neutron scattering measurements. Subsequently, a different kind of time variation of magnetic structure was found in Ca_3Co_2O_6. We describe the features of two kinds of time variations in these materials. A microscopic model of the long-time variation of magnetic structure is presented.

Through a combination of polarization hysteresis loop measurements and piezoresponse force microscopy applied to a uniaxial organic ferroelectric, [H-6,6'-dmbp] [Hca] (6,6'-dimethyl-2,2'bipyridinium chloranilate), we found that head-to-head (or tail-to-tail) charged domain walls are strongly pinned and thus impede bulk polarization switching, whereas antiparallel non-charged walls can participate in the switching process. Our findings suggest that to optimize the polarization switching in terms of magnitude and speed, the multi-domain topology should be considered.

The picosecond time-resolved fluorescence spectra of photosystem II (PS II), a major protein of the plant-type photosynthesis, at 5-180K are compared with the simulated spectra based on a microscopic theory. In the theory, exciton relaxations within a group of pigments and exciton transfers between the groups are treated on the basis of the Redfield theory and the generalized Forster theory, respectively. The simulated spectra well reproduced the temperature dependence of the time-resolved fluorescence spectrum of PS II, which is characterized by the emergence of a 695-nm fluorescence peak upon cooling down to 77K and the decrease of its relative intensity upon further cooling below 77K. The study revealed which chlorophyll molecule on the known PS II structure is responsible for the emission at 695nm.
