Non-adiabatic Current Excitation in Quantum Rings
We investigate the difference in the response of a one-dimensional semiconductor quantum ring and a finite-width ring to a strong and short-lived time-dependent perturbation in the THz regime. In both cases the persistent current is modified through a nonadiabatic change of the many-electron states of the system, but by different mechanisms in each case. PACS numbers: 73.23.Ra, 75.75.+a
متن کاملNon-hermitian Adiabatic Quantum Optimization
Many physical and combinatorial problems associated with complex networks of interacting degrees of freedom can be mapped to equivalent problems of finding the ground (or minimum cost) state of a corresponding quantum Hamiltonian H0 1,2,3,4,5,6,7,8,9. One of the approaches to finding the ground state of H0 is adiabatic quantum computation which can be formulated as follows. Consider the time de...
متن کاملAdiabatic quantum pump of spin-polarized current.
We propose a mechanism by which an open quantum dot driven by two ac (radio frequency) gate voltages in the presence of a moderate in-plane magnetic field generates a spin-polarized, phase-coherent dc current. The idea combines adiabatic, nonquantized (but coherent) pumping through periodically modulated external parameters and the strong fluctuations of the electron wave function existent in c...
متن کاملContinuum and discrete excitation spectrum of single quantum rings
Photoluminescence and excitation of the photoluminescence spectroscopy has been performed in single InGaAs self-assembled quantum rings embedded in a field effect structure device. To determine their electronic structure, bias-dependent optical transitions have been analyzed both, for individual quantum rings, and for the averaged ensemble. Our results are compared with a theoretical model, and...
متن کاملQuantum current modeling in nano-transistors with a quantum dot
Carbon quantum dots (CQDs) serve as a new class of ‘zero dimensional’ nanomaterial’s in thecarbon class with sizes below 10 nm. As light emitting nanocrystals, QDs are assembled from semiconductormaterials, from the elements in the periodic groups of II-VI, III-V or IV-VI, mainly thanks to impacts of quantum confinement QDs have unique optical properties such as brighter, highly pho...
