The advances in free electron laser (FEL) technology allow us to generate intense laser fields in extreme ultraviolet (EUV) and X-ray. Recent studies show that responses of materials to such high-frequency intense laser fields are inherently different from those observed in visible and infrared. In this reveiw, we discuss current progresses in intense laser field physics in EUV and X-ray, especially by focussing on non-linear responses of isolated atoms.

The quantum field theory has been playing important roles in the research of the knot invariants since a connection between the Chern-Simons gauge theory and the Jones polynomial was uncovered. In developments for the past decade, the novel class of knot invariants has been found via the concept of "categorification" in mathematics. On the other hand in the string theory, the concept of "D-brane" has been introduced, and we get new physical interpretation for such knot invariants. In recent years, the unification of various categorified knot invariants has been discussed by combining new approaches in physics and mathematics. In this article, we will survey on recent developments in this researc area.

We have developed novel internal target forming technique (SCRIT) in an electron storage ring, aiming at electron scattering off unstable nuclei. The SCRIT Electron Scattering Facility is now under construction in RIKEN-RIBF. Details of the SCRIT technique and status of the facility are presented in this paper.

Careful and comprehensive beam-dynamics consideration is required to construct modern particle accelerators, especially, large-scale machines for fundamental physics purposes. To design advanced, next-generation accelerators, we must deeply understand the collective behavior of charged-particle beams, that is, the nonlinear many-body system consisting of a single species of charged particles spatially confined by external electromagnetic forces. In this article, a brief introduction is given of a novel tabletop experimental system applicable for fundamental studies of beam dynamics in modern accelerators. The apparatus is based on non-neutral plasma trapping techniques and is called "S-POD" (Simulator for Particle Orbit Dynamics) where we can form a many-body Coulomb system approximately equivalent to a charged-particle beam traveling in an alternating-gradient accelerator. S-POD is particularly useful in exploring the so-called space-charge effects in high-intensity machines and other beam instabilities driven by periodic beam-focusing lattice structures.

The degree of freedom of spin in quantum systems serves as an unparalleled laboratory where intriguing quantum physical properties such as asymmetry or magnetic property can be observed, and the enhanced control of spin may progress physics researches. We developed a novel method for controlling spin in a system of rare-isotope beams, the two-step fragmentation method with the momentum-dispersion matching technique. The present method was demonstrated in an experiment at the RIKEN RI Beam Factory, in which a degree of alignment of 8% was achieved for the spin of a rare isotope ^<32>Al. The figure of merit for the present method was found to be greater than that of the conventional method by a factor of more than 50.
