The equation of state of nuclear matter, which consists of neutrons and protons, has the term that depends on the difference between the neutron and proton densities. Determination of the term, the symmetry energy term, is quite important for nuclear physics as well as nuclear astrophysics. The symmetry energy is one of key ingredients to determine e.g. the radius and internal structure of a neutron star as well as supernova explosion dynamics. The first order density dependence, slope parameter, of the symmetry energy has a close correlation with the thickness of the neutron skin, which is a neutron rich layer that appears on the surface of heavy nuclei. We pick up three recent measurements on the neutron skin thickness of the ^<208>Pb nucleus by using each of weak, electromagnetic, and strong interactions, and report the present situation on the determination of the slope parameter.

The Higgs triplet model is an important example of extended Higgs sectors, because tiny neutrino masses can be explained by the simple mechanism. In this article, we introduce how we can test this model at collider experiments.

We present a study on bond oscillation in CF_4 by means of (e, 2e) electron momentum spectroscopy, a method developed based on electron Compton scattering. Furthermore, we propose time-resolved electron momentum spectroscopy to visualize the change of electron motion in transient species, which is the driving force behind any chemical reactions.

Hexagonal compound Ba_3CoSb_2O_9 approximates the two-dimensional S=1/2 triangular-lattice Heisenberg antiferromagnet, in which a magnetic Co^<2+> ion has an effective spin-1/2. We have performed high-field magnetization measurements on Ba_3CoSb_2O_9 using powdered sample and single crystals. For powdered sample, we found that the entire magnetization curve including the one-third quantum magnetization plateau is in excellent quantitative agreement with the results of theoretical calculations. However, for single crystals, we observed anisotropy in magnetization process. A one-third quantum plateau is clearly observed for H‖ab, whereas for H‖c, the magnetization curve exhibits a cusp near one-third of the saturation field. The suppression of the one-third plateau for H‖c is ascribed to the easy-plane anisotropy. For H‖ab, we found an small magnetization step above the plateau range indicative of a new high-field quantum phase.

Dual-comb spectroscopy using two frequency combs with slightly different repetition frequencies has been attracting attention as a new spectroscopic tool. Dual-comb spectroscopy can be considered as a Fourier transform spectroscopy without the mechanical delay-stage. Dual-comb spectroscopy has much higher data acquisition rate and frequency resolution, compared with conventional Michelson interferometerbased Fourier transform spectroscopy. In this paper, we introduce the principle of dual-comb spectroscopy and novel way for phase locking between two frequency combs for simple dualcomb system. In addition, the application of dual-comb spectroscopy to FBG strain sensor is described.
