Dynamics of two dimensional electrons under the strong perpendicular magnetic field is shown to be described by a multi-component fermion theory. The electric conductance has a remarkable property… Expand

We investigate the thermal and curvature effects to dynamical symmetry breaking in a four-fermion model. The effective potential is evaluated in the leading order of the 1/N expansion at finite… Expand

Chiral anomaly in (2+1)-dimensional fermion theory coupled with an external electromagnetic field is studied. Its connection with the quantized Hall effect is pointed out. Hall conductivity is… Expand

For the first time, the decay pattern of low-lying strength in a neutron-rich nucleus is measured and is not consistent with several mean-field theory descriptions of the pygmy states.Expand

Using a momentum representation of a magnetic von Neumann lattice, we study a two-dimensional electron in a uniform magnetic field and obtain one-particle spectra of various periodic short-range… Expand

A quantum mechanical wave of a finite size moves like a classical particle and shows a unique decay probability. Because the wave function evolves according to the Schr\"{o}dinger equation, it… Expand

The stellar reaction {sup 26}Si(p, {gamma}){sup 27}P was studied in the Coulomb dissociation of {sup 27}P. Two known resonance levels in {sup 27}P were excited and a candidate for the third excited… Expand
