Spin and Charge Transfer in Selected Nanostructures
The general theme in this thesis is the interplay between electron spin and charge in nanoscale transport phenomena. The main presentation is divided into three independent chapters. In chapter 2, we propose a mechanism that explains the excess damping and dynamic exchange interactions which are observed in ferromagnet/paramagnet hybrids. A moving ferromagnetic magnetization emits spin current ...
متن کاملManipulating charge transfer excited state relaxation and spin crossover in iron coordination complexes with ligand substitution.
Developing light-harvesting and photocatalytic molecules made with iron could provide a cost effective, scalable, and environmentally benign path for solar energy conversion. To date these developments have been limited by the sub-picosecond metal-to-ligand charge transfer (MLCT) electronic excited state lifetime of iron based complexes due to spin crossover - the extremely fast intersystem cro...
متن کاملSpin and energy transfer in nanocrystals without transport of charge
We describe a mechanism of spin transfer between individual quantum dots that does not require tunneling. Incident circularly-polarized photons create inter-band excitons with non-zero electron spin in the first quantum dot. When the quantum-dot pair is properly designed, this excitation can be transferred to the neighboring dot via the Coulomb interaction with either conservation or flipping o...
متن کاملPerfect state transfer in quantum spin networks.
We propose a class of qubit networks that admit the perfect state transfer of any quantum state in a fixed period of time. Unlike many other schemes for quantum computation and communication, these networks do not require qubit couplings to be switched on and off. When restricted to N-qubit spin networks of identical qubit couplings, we show that 2log3N is the maximal perfect communication dist...
متن کاملCharge-state conditional operation of a spin qubit.
We report coherent operation of a singlet-triplet qubit controlled by the spatial arrangement of two confined electrons in an adjacent double quantum dot that is electrostatically coupled to the qubit. This four-dot system is the specific device geometry needed for two-qubit operations of a two-electron spin qubit. We extract the strength of the capacitive coupling between qubit and adjacent do...
