We develop a theory of electron transport through quantum dots that are weakly coupled to
ferromagnetic leads. The theory covers both the linear and nonlinear transport regimes …

As spintronics goes nano, new phenomena are predicted resulting from the interplay
between spin dependent transport and single electron physics. The long term goal of …

We present a density-matrix rate-equation approach to sequential tunneling through a metal
particle weakly coupled to ferromagnetic leads. The density-matrix description is able to deal …

Spin-dependent transport through an interacting single-level quantum dot coupled to
ferromagnetic leads with noncollinear magnetizations is analyzed theoretically. The …

A method developed by Sandalov [Int. J. Quantum Chem. 94, 113 (2003)] is applied to
inelastic transport in the case of strong correlations on the molecule, which is relatively …

An analytical expression for the current through a single level quantum dot for arbitrary
strength of the on-site electron-electron interaction is derived beyond mean-field theory. By …

Based on Keldysh's nonequilibrium Green function method, the spin-dependent transport
properties in a ferromagnet–quantum dot (QD)–ferromagnet coupled system are …

A theory for asymmetric current-voltage characteristics, in particular negative differential
conductance, for double quantum dots with strongly correlated electron states is formulated …

An explanation for the asymmetries in the current-voltage characteristics in mesoscopic
quantum systems weakly coupled to reservoirs is proposed. Thus, it is suggested that …

We propose an efficient mechanism for the operation of writing spin in a quantum dot, which
is an ideal candidate for qubit. The idea is based on the Andreev reflection induced spin …
