It is found that the decay rate of the quantum fidelity is suppressed when the periodic orbit scars in the accumulation of the time-evolving wavefunction become obvious in two-dimensional (2D) nanostructure The fidelity is numerically evaluated by...
Recently, a brand-new phenomenon induced by microwave radiation was observed in AB ring systems. That is, a significantly wide dip appears in the magnetoresistance of AB ring structures in a weak magnetic field range. Its position (strength of a m...

The time-evolution of the wavepacket inside chaotic and integrable two-dimensional (2D) nanostructures is numerically studied. We have found the enhancement around the classical periodic orbits during the time-evolution in the stadium billiard. It...

In this work, we numerically study electron transfer in two-dimensional quantum rings (QRs) by using a wavefunctional nodal pattern analysis. Recent progress in experimental techniques for nanostructures has enabled precise control of the electron...

The time-evolution of the wave packet inside chaotic and integrable two-dimensional nanostructures is numerically studied. Recently the time-evolution of quantum states is seriously considered to treat the dynamical property of nanostructures. By ...
