The mesoscopic spin system formed by the 10 4–10 6 nuclear spins in a semiconductor
quantum dot offers a unique setting for the study of many-body spin physics in the …

The interaction of an electronic spin with its nuclear environment, an issue known as the
central spin problem, has been the subject of considerable attention due to its relevance for …

We propose an interface between the spin of a photon and the spin of an electron confined
in a quantum dot embedded in a microcavity operating in the weak-coupling regime. This …

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 …

Crystals spontaneously break the continuous translation symmetry of free space.
Analogously, time crystals lift translational invariance in time. Here we demonstrate a robust …

Topological insulators (TIs), with their helically spin-momentum–locked topological surface
states (TSSs), are considered promising for spintronics applications. Several recent …

The ability to store optical information is important for both classical and quantum
communication. Achieving this in a comprehensive manner (converting the optical field into …

The nuclear quadrupole interaction eliminates the restrictions imposed by hyperfine
interaction on the spin coherence of an electron and nuclei in a quantum dot. The strain …

Optical and electrical control of the nuclear spin system allows enhancing the sensitivity of
NMR applications and spin-based information storage and processing. Dynamic nuclear …

The spin dynamics of localized charge carriers is mainly driven by hyperfine interaction with
nuclear spins. Here we develop a theory of hyperfine interaction in transition metal …
