Tuning light emission in bulk and quantum structures by strain constitutes a complementary method to engineer functional properties of semiconductors. Here, we demonstrate the tuning of light emission of GaAs nanowires and their quantum dots up to 115 meV by applying strain through an oxide envelope. We prove that the strain is highly anisotropic and clearly results in a component along the NW lon
The aim of this work is to investigate how a quantised photon cavity modifies the spin dynamics of a two-site spin-electron dimer with Rashba spin-orbit coupling. The cavity couples to inter-site hopping through the Peierls substitution. Dissipation is included via the Lindblad master equation. Three numerical methods were tested to see which would be best suited for the time evolution of the syst
We report on an extremely narrow linewidth of a two-dimensional electron-gas photoluminescence in GaAs/AlGaAs quantum wells pumped by ultrasonic vibrations. Below the threshold pumping amplitude, the observed emission line is weak, broad, and undergoes a redshift consistent with the evolution of an electron-hole plasma recombination in the oscillating piezoelectric fields accompanying the sample v
We theoretically consider charge transport through two quantum dots coupled in series. The corresponding full counting statistics for noninteracting electrons is investigated in the limits of sequential and coherent tunneling by means of a master equation approach and a density matrix formalism, respectively. We clearly demonstrate the effect of quantum coherence on the zero-frequency cumulants of
3 november 2025 14:00 till 16:00 | Föreläsning “The Observer Problem” is a cross-disciplinary research project that takes this shared challenge as its starting point. Led by artist Rosa Barba and physicist Puneet Murthy, it brings together quantum optics and cinematic installation to explore observation as both a physical process and an experiential event. The project does not aim to simply illu

Alternative methods for accurate in vitro assessment of skin and respiratory sensitizers are urgently needed. Sensitization is a complex biological process that cannot be evaluated accurately using single events or biomarkers, since the information content is too restricted in these measurements. On the contrary, if the tremendous information content harbored in DNA/mRNA could be mined, most compl
Effective electron supply to produce ammonia in photoelectrochemical nitrogen reduction reaction (PEC NRR) remains challenging due to the sluggish multiple proton-coupled electron transfer and unfavorable carrier recombination. Herein, InP quantum dots decorated with sulfur ligands (InP QDs-S2−) bound to MIL-100(Fe) as a benchmark catalyst for PEC NRR is reported. It is found that MIL-100(Fe) can

PhD student at the Malmö Academy of Music, composer and sound artist Yann Coppier investigates this question through a concert and a 50% PhD seminar.Conce

Quantum computing is a potentially disruptive field, and a significant amount of resources are invested in technology advancements. The business-related research, however, is a relatively unexplored area. This master’s thesis explores the key factors that buyers consider when purchasing quantum computing hardware, the perception towards start-ups versus established quantum computing companies, and
