One-dimensional quantum systems show fascinating properties beyond the scope of the mean-field approximation. However, the complicated mathematics involved is a high barrier to non-specialists. Written for graduate students and researchers new to the

Heavy electrons are found among a number of lanthanide and actinide compounds, and are characterized by a large effective mass which becomes comparable to the mass of a muon. Heavy electrons exhibit rich phenomena such as unconventional superconducti

Magnetic excitations in layered electride ${\mathrm{Y}}_{2}\mathrm{C}$ have been found by inelastic neutron scattering. We have observed weak but clear magnetic scattering around the wave number $Q=0$, but no magnetic order down to the lowest tempera

In the ordinary mean field theory, the effective field is static. If one allows temporal variation of the effective field, fluctuation effects of the corresponding field can be included. The correlation problem in a large system is then replaced by a

Perturbation theory is one of the standard subjects in elementary quantum mechanics. The connection to renormalization emerges naturally if one adopts a generalized view on perturbation theory. While the ordinary perturbation theory derives approxima

The Fermi liquid theory constructed by Landau efficiently describes strongly correlated fermions in terms of small number of parameters. The core of the theory is the concept of quasi-particles. This chapter explains how the Fermi liquid theory accou

The linear response means a change in the system proportional to the magnitude of the external force. If the external force is infinitesimally small, the higher order effects can safely be neglected. Actually the dominance of linear response often ex
