Materials Physics with Electromagnetic Waves is to be defined as the research field of materials science using the interaction between electromagnetic waves and the materials themselves. Within this filed, NMR and μSR activities that have been developed in a unique way in Japan are reviewed. Those techniques have played a crucial role in understanding the microscopic properties of magnetism and superconductivity. It is also emphasized that these experimental developments have been tightly coupled to theoretical developments and have established a characteristic research culture in Japan.

Flavor physics, in which symmetry breaking and violation of conservation lows in reactions of leptons and hadrons are studied, has played an important role in particle physics, and it has been complementary to searches for new particles at high energy colliders. The supersymmetric standard model is one of the most promising models beyond the standard model, and it is expected to be discovered and confirmed in the near future. Flavor physics will play an important role in these processes again. Especially, it may give clues for the questions such as, "what is the origin of the supersymmetry breaking?" and "what is the model beyond the supersymmetric standard model?".

Novel concepts and phenomena are emerging recently in the physics of quantum Hall effect. This article gives an overview, which starts from the fractional quantum Hall system viewed as an extremely strongly correlated system, and move on to present various phenomena involving internal degrees of freedom (spin and layer), non-equilibrium and optical properties, and finally the spinoff to anomalous Hall effect and the rotating Bose-Einstein condensate.

Gaussian expansion method that has been proposed and developed by the authors is reviewed. The method takes all the sets of rearrangement Jacobi coordinates and constructs the few-body Gaussian basis functions on the coordinates, setting the Gaussian ranges to lie in geometric progression. The method is suited for describing both the short-range correlations and long-range tail behavior, and has extensively been applied to various types of few-body problems in physics including both bound states and scattering states.

Hydrogen molecules are excited to Rydberg states with n=16, 17 in the presence of inhomogeneous field of an electric dipole by a vacuum ultraviolet-ultraviolet double resonance scheme. The large dipole moment produced in Stark eigenstates leads to strong forces on the molecules in the inhomogeneous electric field. Deflection and deceleration are demonstrated for a pulsed supersonic beam containing the H_2 molecules in the n=16, 17, N^+=2, M_J=0 Rydberg states. The Rydberg states are found to survive for over 100μs after the dipole field is switched off. The Rydberg states have a special stability with respect to decay by predissociation. Complete deceleration to the zero mean velocity is numerically demonstrated for H_2 molecules in the highest linear low-field-seeking n=16, M_J=0 Rydberg states by using a simplectic integrator of the fourth order. The calculations show that the initial velocity of 900 ms^<-1> with translational temperature 1 K is decelerated to 0 ms^<-1> with 13 mK.

An extended version of the time-dependent Hartree-Fock theory, known as the time-dependent density-matrix theory (TDDM), is presented. It is pointed out that TDDM has a close relation with pairing theories such as the Hartree-Fock-Bogoliubov theory and the quasiparticle random phase approximation. TDDM is applied to the ground states and quadrupole states of ^<20>O and ^<22>O. The obtained results are compared with those obtained from the pairing theories.
