In recent years, the physics community has experienced a revival of interest in spin effects in
solid state systems. On one hand, the solid state systems, particularly, semiconductors and …

The optical spectrum of a quantum dot is typically dominated by the fundamental transition
between the lowest-energy configurations. However, the radiative Auger process can result …

Quantum dots are arguably the best interface between matter spin qubits and flying photonic
qubits. Using quantum dot devices to produce joint spin-photonic states requires the …

We present a theoretical and experimental investigation of exciton recombination dynamics
and the related polarization of emission in highly in-plane asymmetric nanostructures …

We demonstrate the optical addressability of the spin of an individual chromium atom (Cr)
embedded in a semiconductor quantum dot. The emission of Cr-doped quantum dots and …

When a detuned and strong laser pulse acts on an optical transition, a Stark shift of the
corresponding energies occurs. We analyze how this optical Stark effect can be used to …

Contrary to simplified theoretical models, atomistic calculations presented here reveal that
sufficiently large in-plane shape elongation of quantum dots can not only decrease, but even …

We report on a theoretical study of the hole states in II-IV quantum dots of spherical and
ellipsoidal shapes, described by smooth potential confinement profiles that can be modeled …

We demonstrate comprehensive numerical studies on a hybrid III-V/Si-based waveguide
system, serving as a platform for efficient light coupling between an integrated III-V quantum …

Precision measurements of optical phases have many applications in science and
technology. Entangled multiphoton states have been suggested for performing such …
