The scientific effort to control the interaction between light and matter has grown
exponentially in the last 2 decades. This growth has been aided by the development of …

Interest in the multiple facets of optical vortices has flourished in the last three decades. This
review examines the basic research and applications of the interplay between optical …

Time-dependent density-functional theory (TDDFT) describes the quantum dynamics of
interacting electronic many-body systems formally exactly and in a practical and efficient …

We consider a quantum-gate mechanism based on electron spins in coupled semiconductor
quantum dots. Such gates provide a general source of spin entanglement and can be used …

Nanophotonics is where photonics merges with nanoscience and nanotechnology, and
where spatial confinement considerably modifies light propagation and light-matter …

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 …

Quantum dots or rings are artificial nanometre-sized clusters that confine electrons in all
three directions. They can be fabricated in a semiconductor system by embedding an island …

Understanding the real-time evolution of many-electron quantum systems is essential for
studying dynamical properties in condensed matter, quantum chemistry, and complex …

The size-dependent band gap of semiconductor quantum dots is a well-known and widely
studied quantum confinement effect. In order to understand the size-dependent band gap …

The role of quantum confinement (QC) in Si and Ge nanostructures (NSs) including quantum
dots, quantum wires, and quantum wells is assessed under a wide variety of fabrication …
