The S=1/2 distorted diamond chain is investigated by the density matrix renormalization group and the numerical exact diagonalization. We found that an incommensurate long-range order is induced by the external magnetic field above the 1/3 magnetization plateau. We using this result theoretically explain the field induced incommensurate order observed in the azurite.

A guiding-centre fundamental 1-form whose symplectic part does not include the EB term is derived by the Lie-transform perturbation method. Since the symplectic part of the derived 1-form is the same as the standard one without the strong EB flow formally, it yields the standard Lagrange and Poisson brackets. Therefore the guiding-centre Hamilton equations also keep the standard form. The guiding-centre Hamiltonian is rather complicated compared to the previous ones. However, it is possible to simplify the Hamiltonian in localised transport barrier region like the tokamak H-mode edge.

Liquid drop model is a representative model to describe binding energy and size of nuclei. This model is well reproduces bulk properties of nuclei even in current studies on nuclei. In this presentation, we investigate nuclear symmetry energy and nuclear surface energy by using the nuclear liquid drop model with some higher-order terms. The coefficients of these term are determined so as to reproduce measured nuclear masses of approximately 2200 nuclides. From this analysis we find an indication that the fourth-order terms of the symmetry energy is required and the curvature term of it is negligible. Regarding a mass-number dependency on nuclear radius, we also find that the dependency of lighter nuclei (typically with mass number, 
) is larger than that of heavier nuclei.

We have developed a hybrid-anvil high-pressure device for single-crystal magnetic neutron diffraction beyond 3 GPa. The device consists of an opposed pair of an upper sapphire anvil and a lower WC anvil. Maximum pressure generated by the device is 7 GPa. To increase the maximum pressure up to 10 GPa, we tried three types of the lower anvil instead of the simple sapphire anvil. One is a sapphire anvil with a thin diamond cap, another is a sapphire anvil supported by a MP35 alloy, and the other is a SiC anvil supported by a MP35 alloy. We found that the modified hybrid-anvil, that is, the combination of the WC anvil and the supported SiC anvil could generate the pressure of 10 GPa at the load of 3.8 tons. The size of the sample chamber under 10 GPa was about 1 mm diameter and 0.25 mm height, which is sufficient for magnetic neutron diffraction experiments. We succeed in the magnetic neutron diffraction experiments on the RBC (R=Dy, Ho) up to 9 GPa with the modified hybrid-anvil device.

T-dependence and anisotropy of Knight shift and spin-lattice relaxation time T1 of In-NMR have been determined in heavy fermion superconductor CeIrIn. Knight shift and T1 show a strong anisotropy. Knight shift versus static susceptibility plot is non-linear at low temperatures, indicating that the hyperfine coupling depends on temperature. The origin of hyperfine interaction and anisotropy of spin fluctuations will be discussed.
