Nanomagnetism in semiconductor quantum structures for applications in spintronics and quantum information technology
Currently I'm working primarily with the quantum transport of electrons and the Wigner-localization in all-electric spin-polarizers and spin valves. The aim of the project is to theoretically model the corresponding electron states and determine under what conditions the spontaneous local magnetization and demagnetization, crystalline order (magnetic Wigner lattice) etc. may occur. The magnetic states have often exotic nature, and are therefore vital area of research. For example it leads to the spontaneous excitation of a quantum point contact that only electrons of a given spin direction can pass the quantum point contact which can be used for selective spin injection. The phenomenon has principal interest in the new field of semiconductor spin electronics.
