Investigations of emergent symmetry breaking phenomena occurring in small finite-size
systems are reviewed, with a focus on the strongly correlated regime of electrons in two …

The rapid rise of spintronics and quantum information science has led to a strong interest in
developing the ability to coherently manipulate electron spins. Electron spin resonance is a …

An asymmetric pair of coupled InAs quantum dots is tuned into resonance by applying an
electric field so that a single hole forms a coherent molecular wave function. The optical …

Exchange-coupled spin qubits in semiconductor nanostructures are shown to be vulnerable
to dephasing caused by charge noise invariably present in the semiconductor environment …

We study spin dynamics for two electrons confined to a double quantum dot under the
influence of an oscillating exchange interaction. This leads to driven Rabi oscillations …

We introduce a Hubbard model as the simple quantum generalization of the classical
capacitance circuit model to study semiconductor quantum-dot spin qubits. We prove …

We describe time-dependent single-electron transport through quantum dots in the Coulomb
blockade regime. Coherent dynamics of a single charge qubit in a double quantum dot is …

We analyze theoretically and experimentally the electronic structure and charging diagram
of three coupled lateral quantum dots filled with electrons. Using the Hubbard model and …

Crystal phase quantum dots (QDs) are formed during the axial growth of III–V semiconductor
nanowires (NWs) by stacking different crystal phases of the same material. In III–V …

A lateral quantum dot design for coherent electrical manipulation of a two-level spin-charge
system is presented. Two micron-size permanent magnets integrated to high-frequency …
