Antiferromagnetic Skyrmions

Cooperation and competition between quantum effect and non-linear effect in strongly interacting electron systems provide a number of exotic superconductivity, magnetism, dielectrics and others, which have attracted much attention from fundamental and application points of view.

Hypernuclei as relativistic baryon many-body systems

In recent years, the so called “beyond-mean-field approach” has been rapidly developing owing to the development of computer powers. In this approach, the symmetries broken in the mean-field approximation are restored by the projection technique, and in addition, a quantum fluctuation of the mean-field is also taken into account. We have applied this approach to hypernuclei, and for the first time we have succeeded in describing spectra of hypernuclei based on a relativistic baryonic many-body approach.
