In the thesis, three-dimensionally confined resonant tunneling structures were studied experimentally. Two approaches were used for obtaining quantum confinement: gate-defined lateral constriction of double barrier structures, and epitaxial growth of self-assembled quantum dots. In addition, the thesis deals with the basic development of large-area double barrier resonant tunneling diodes, as a st

Swedish parents today raise their children in a welfare state, where childcare is both accessible and affordable, and often within dual-income households. At the same time, they have witnessed a challenged welfare state affected by cutbacks, privatizations, and the demands of an increasingly flexible working life.

Tillsammans med industrin utvecklar vi nya idéer inom material, tillverkning och materialåtervinning. Målet är att hitta lösningar som både ser till miljön och stärker företagens konkurrenskraft. Industrin förbrukar cirka en tredjedel av Sveriges energi och mycket av miljöbelastningen av vår konsumtion kommer från material som finns i bruksprodukter som exempelvis redskap, hushållsmaskiner och for

The impact of coherence on the nonlinear optical response and stationary transport is studied in quantum cascade laser structures. Nonequilibrium effects such as the pump-probe signals, the spatiotemporally resolved electron density evolution, and the subband population dynamics (Rabi flopping) as well as the stationary current characteristics are investigated within a microscopic density-matrix a

While farmed fish is often presented as a promising solution for food security, it still depends heavily on capture fisheries—specifically s

We study the transient dynamics subject to quantum coherence effects of two interacting parallel quantum dots weakly coupled to macroscopic leads. The stationary particle current of this quantum system is sensitive to perturbations much smaller than any other energy scale, specifically compared to the system-lead coupling and the temperature. We show that this is due to the presence of a parity-li
Popular Abstract in Swedish I denna avhandling studeras egenskaper hos tvådimensionella, kvantmekaniska mångpartikelsystem. Studierna utförs med spinndensitetsfunktionalteori (SDFT) med den lokala spinndensitetsapproximationen (LSDA), samt med numerisk exakt diagonalisering. De egenskaper som studeras inkluderar symmetribrytande tillstånd i kvantprickar med få elektroner, gap i inneslutna fåpartik
High-order Harmonic Generation (HHG) is a highly non-linear process in which an atom interacts with a strong laser field. The laser field lowers the atomic potential barrier allowing bound electrons to escape into the continuum through tunnel ionization, propagate, and, with some probability, recombine with the parent ion. As a result, coherent eXtreme UltraViolet (XUV) radiation is emitted in the
In this thesis we focus on improvements of the description of the electron-electron correlation effects in nonequilibrium nanosystems. We mainly focus on developments of two nonequilibrium methods, namely the formalism of Nonequilibrium Green’s Function and Time Dependent Density Functional Theory and we explore the possibility to improve existing approximations in these theories. A smaller part o
