We consider a single electron in a 1D quantum dot with a static slanting Zeeman field. By
combining the spin and orbital degrees of freedom of the electron, an effective quantum two …

Technological growth in the electronics industry has historically been measured by the
number of transistors that can be crammed onto a single microchip. Unfortunately, all good …

We have developed nanoscale double-gated field-effect-transistors for the study of electron
states and transport properties of single deliberately implanted phosphorus donors. The …

We perform Landau-Zener-Stückelberg interferometry on a single electron GaAs charge
qubit by repeatedly driving the system through an avoided crossing. We observe coherent …

We propose and analyze a new scheme of realizing both spin filtering and spin pum** by
using ac-driven double quantum dots in the Coulomb blockade regime. By calculating the …

The creation, transfer, and stabilization of localized excitations are studied in a donor–
acceptor Frenkel exciton model in an atomistic treatment of reduced-size double quantum …

We consider current shot noise and the full counting statistics in a chain of quantum dots
which exhibits a continuous nonequilibrium phase transition as a function of the tunnel …

We report on our recent progress in applying semiconductor quantum dots for spin-based
quantum computation, as proposed by Loss and DiVincenzo (1998 Phys. Rev. A 57 120) …

We use photon-assisted tunneling (PAT) and an inhomogeneous Zeeman field to
demonstrate spin-selective PAT readout with a double quantum dot. The inhomogeneous …

We use Pauli-spin blockade in two-electron vertical double quantum dots to quantitatively
estimate the exchange energy J in a wide range of interdot level detuning Δ and fully …
