The macroscopic quantum tunneling (MQT) of a planar domain wall in a ferromagnetic metal is studied based on the Hubbard model. The crucial difference from the case of the insulator is that the ohmic dissipation is present even at zero temperature due to the Stoner excitations characteristic of the
The Josephson effect is one manifestation of the quantum aspect of macroscopic objects. It has been tested in various macroscopic systems to confirm their quantummechanical nature. In some of the systems, the total number of particles in the system is fixed. In such a case, the dynamics of the syst
