We consider the electronic properties of a system consisting of two quantum dots in physical proximity, which we will refer to as the double-Qdot. Double-Qdots are attractive in light of their potential application to spin-based quantum computing and other electronic applications, e.g. as specialized sensors. Our main goal is to derive the essential properties of the double-Qdot from a model that is rigorous yet numerically tractable, and largely circumvents the complexities of an ab initio simulation....
Wavefunctions of symmetrical nanoparticles are considered making use of induced representation method. It is shown that when, at the same total symmetry, the order of local symmetry group decreases, additional quantum numbers are required for complete labelling of electron states. It is shown that the labels of irreducible representations of intermediate subgroups can be used for complete classification of states in the case of repeating IRs in symmetry adapted linear combinations. The intermediate...
We study the dispersion relations and spectra of invariant Schrödinger operators on a graphyne structure (lithographite). In particular, description of different parts of the spectrum, band-gap structure, and Dirac points are provided.
Stimuli-responsive polymers result in
on-demand regulation of properties and functioning of various
nanoscale systems. In particular, they allow stimuli-responsive
control of flow rates through membranes and nanofluidic devices
with submicron channel sizes. They also allow regulation of drug
release from nanoparticles and nanofibers in response to
temperature or pH variation in the surrounding medium. In the
present work two relevant mathematical models are introduced to
address precipitation-driven...
