A relativistic transient absorption theory is derived, implemented and validated within the dipole approximation based on the time-dependent Dirac equation. In the non-relativistic limit, it is found that the absorption agrees with the well established non-relativistic theory based on the time-dependent Schrödringer equation. Time-dependent simulations have been performed using the Dirac equation
In the perpetuated absence of wide-ranged aging-related programs in Indonesia, more than one-quarter of the elderly population rely on the family especially adult children, resulting in the prevalence of three-generation households. This research seeks to explain the underlying motive and the practice of caring for the elderly parent from the vantage point of adult children that act as the main su
Abstract in UndeterminedHigh penetration of variable generation such as wind power increases the demands on frequency control. The same applies to island operation and in particular if this involves variable generation, which is planned at the Danish island Bornholm. While it is obvious that the frequency control need to be considered, the disturbances caused to this control by the hourly dispatch
Med nanoteknik finns nycklar till hållbara lösningar för planetens och människans bästa. Energieffektivare, smartare, starkare, miljövänligare material har blivit möjliga att skapa på naturens eget sätt. NanoLund vid Lunds universitet är en mycket stark, ledande tvärvetenskaplig forskningsmiljö. Inför etableringen av NanoLunds nya renrumslaboratorium, Nanolab Science Village, bjuder Lunds universi
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
The rotation of a quantum liquid induces vortices to carry angular momentum. When the system is composed of multiple components that are distinguishable from each other, vortex cores in one component may be filled by particles of the other component, and coreless vortices form. Based on evidence from computational methods, here we show that the formation of coreless vortices occurs very similarly
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

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
