Current-constraining variational approaches to quantum transport

Stochastic Variational Approaches to Non-Hermitian Quantum-Mechanical Problems

Resonances are very interesting phenomena, which appear in a wide range of classical and quantum systems. The mathematical description of quantum-mechanical resonances is connected with complex eigenvalues of the Hamiltonian of a given system. This fact introduces various difficulties, especially since resonance eigenfunctions are not normalisable. This work aims at developing techniques for th...

Quantum 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...
