Properties of exchange interactions in magnetic semiconductors
(Lappeenranta-Lahti University of Technology LUT, 2020-12-02)
This dissertation is devoted to the investigation of magnetic properties of nanostructures with magnetic impurities. The properties of electron spin relaxation in magnetically doped quantum well was investigated. It has ...
Interplay of local moments and itinerant electrons
(Lappeenranta-Lahti University of Technology LUT, 2020-10-02)
We have studied the electronic structure of materials whose properties are driven by magnetism. This work requires research with computer simulations based on quantum mechanics laws within the density functional theory ...
Parameter Estimation of Large-Scale Chaotic Systems
(Lappeenranta-Lahti University of Technology LUT, 2020-10-30)
Parameter estimation plays a crucial role in modelling various kinds of phenomena. However, it can be challenging to properly calibrate a model to satisfy the observed quantities and provide reliable forecasts. In the case ...
Statistical parameter identification of reaction-diffusion systems by Turing patterns
(Lappeenranta-Lahti University of Technology LUT, 2020-12-14)
Mathematical models allow a connection to be made between a pattern observed on a macroscopic scale and a hypothetical underlying mechanism. Different mechanisms, however, can result in similar patterns. In developmental ...
