Presentation

I do research in fundamental quantum physics and semiconductor nanotechnology by studying nanometer-sized semiconductor structures that confine electrons in the quantum dots and quantum wires.

With the help of this research one can create artificial objects whose properties are controlled by quantum mechanical laws. Potentially, such quantum structures important for future spintronics, microelectronics, photonics and quantum informatics, because quantum mechanics in principle offers new solutions and functionality of semiconductor structures and components that are constantly miniaturized and within a few years will have been reduced to nanotechnology with sizes of a few tens of nanometers or less.

Current research

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.
