Charge Tunneling Rates in Ultrasmall Junctions
With the advances of microfabrication techniques in recent years it has become possible to fabricate tunnel junctions of increasingly smaller dimensions and thereby decreasing capacitance C. Nowadays

Spin-flip transitions between Zeeman sublevels in semiconductor quantum dots
We have studied spin-flip transitions between Zeeman sublevels in GaAs electron quantum dots. Several different mechanisms which originate from spin-orbit coupling are shown to be responsible for
Coherent Control of a Single Electron Spin with Electric Fields
The experimentally realized coherent control of a single-electron spin in a quantum dot using an oscillating electric field generated by a local gate to establish the feasibility of fully electrical manipulation of spin qubits.
Superconducting nanowires as quantum phase-slip junctions
For a superconductor, charge and phase are dual quantum variables. A phase-slip event in a superconducting nanowire changes the phase difference over the wire by 2π; it is the dual process to
Spin relaxation in semiconductor quantum dots
Quantum dots ~QD’s ! are small conductive regions in semiconductor structures that contain a tunable number of carriers. The shape and size of quantum dots can be controlled by the gate voltage. The

Electron transport in a double quantum dot governed by a nuclear magnetic field.
It is shown that for a given realization of nuclear magnetic field spin blockade can be restored by tuning external magnetic field; this may be useful for quantum manipulation of the device.
Full counting statistics of charge transfer in Coulomb blockade systems
Full counting statistics (FCS) of charge transfer in mesoscopic systems has recently become a subject of significant interest, since it proves to reveal an important information about the system
Pauli spin blockade in the presence of strong spin-orbit coupling
We study electron transport in a double quantum dot in the Pauli spin blockade regime in the presence of strong spin-orbit coupling. The effect of spin-orbit coupling is incorporated into a modified
