Recent studies of the ballistic transport in the mesoscopic systems performed in our laboratory are reviewed in the present paper. In the first half of the present paper, we investigate the characteristics of ballistic transport in quantum wires of w

As a representative Kondo system, consisting of a magnetic atom adsorbed on a metal surface, we consider a Co adatom on a Cu(111) surface. We introduce general expressions for the tunneling current and the differential conductance dI/dV, and discuss

We investigate the effects of photoexcited-hole decay on time-resolved two-photon photoemission spectra of metal surfaces by non-equilibrium Green function method. We show that it is necessary for calculating the photoelectron intensity to introduce

We have investigated the transport and magnetic properties of the atom bridge made from magnetic materials, which is the atom-scale wire constructed between a scanning tunneling microscope (STM) tip and a solid surface, by the use of ab initio calcul

Microscopic mechanisms of energy relaxation and dephasing in two-photon photoemission (2PPE) from metal surfaces are investigated by nonequilibrium Green function method. It is shown that the dephasing time corresponds to the lifetime of a hole excit

We study effects of an oxygen vacancy on the electronic state of the CuO 2 plane in the normal state, on the basis of the d – p model. We calculate the local density of states at copper sites and oxygen sites around the p x -oxygen vacancy, at T =

We investigate how the deformation of an atom bridge, made of Fe, between a scanning tunneling microscope tip and a solid surface affects the magnetic state of the atom bridge within the density functional simulations. For atom bridges of chain struc

We study the ground state energy/properties of a system of interacting electrons confined one-dimensionally, with the aid of the Bethe ansatz method. We first derive a set of fundamental equations, explicitly taking into account the confinement of th

Steric effect on the o-p conversion of a H 2 interacting with a 3d impurity sitting on a metal oxide surface is investigated by comparing the o-p conversion yield/rate for a H 2 doing cartwheel-like rotation (i.e., the rotational axis of H 2 is paral
