Recently, in information science, information processing based on signal sparsity has been intensively investigated. This is because a quite impactive idea for reconstruction of sparse signal, called compressed sensing, was proposed about ten years ago, which has been widely spread onto variety of fields in information science. In this article the author attempts to elucidate the relationship between theoretical physics and information theory through random matrix theory, and to attract the physicists' interests onto this problem.

A Variety of Dynamics in Organic Crystals Having Strong Electron-Lattice Interaction

We studied photoinduced dynamics in an organic crystal (EDO-TTF)_2PF_6, which has strong electron-electron and electron-lattice interactions, by applying four types of ultrafast techniques. Using 10fs reflectivity change measurement, we found that a new state emerges over 40fs. The optical conductivity spectrum at 100fs from mid-infrared to visible light revealed this state to be a photoinduced phase which has never seen in thermal equilibrium. The crystal and molecular structural changes over 100ps were studied using picosecond infrared vibrational spectroscopy and femtosecond electron diffraction and it is figured out that molecular deformation is much slower than its translation.

Entanglement Entropy and Conformal Field Theory(Quantum Realm-Nonlocal Correlation and Uncertainty-)

Entanglement entropy (EE), which is an important quantity in the quantum information science, has recently attracted a great attention as a new tool for probing the universal properties of quantum many-body systems. In one-dimensional quantum critical systems, the scaling of EE on a single interval in the system can be used to determine the central charge, a universal number, of the underlying conformal field theory (CFT). Recent studies have shown that the EE contains more refined information of CFT if it is calculated on two disjoint intervals in the system. This article reviews some basic knowledge on EE and recent developments on the connection between EE and CFT.

Preparation of an Aligned O_2 Beam and the Clarification of the Aluminum Oxidation Dynamics(Research)

A single spin-rotational state-selected O_2 beam was developed by combining a supersonic seeded O_2 beam with a hexapole magnet. It permits a precise analysis of the molecular alignment effect and the spin effect in O_2 chemisorption. The dynamical process of O_2 adsorption on an Al(111) surface, despite intensive studies, has remained unresolved because of the lack of conclusive experimental evidences that verify the reaction mechanisms proposed previously. The alignment resolved O_2 sticking on Al(111) has clarified that O_2 molecules parallel to the surface have much higher sticking probabilities than those perpendicular to the surface at translational energies less than 0.2eV. This proves that the abstraction process is a minor event at low energy conditions.

Phase Competition and Spatial Inhomogeneity Induced by Molecular Degrees of Freedom(Research)

Internal degrees of freedom are a fundamental concept penetrating into various fields of physics. The organic molecular conductors possess unique molecular degrees of freedom, which lead to complex electronic and magnetic phases at low temperatures. Here we review a novel phase-competition phenomenon associated with large-scale spatial inhomogeneity emerged in a border of such ordered states.
