We devise an autonomous quantum thermal machine consisting of three pairwise-interacting qubits, two of which are locally coupled to thermal reservoirs. The machine operates autonomously, as it requires no time-coherent control, external driving or quantum bath engineering, and is instead propelled by a chemical potential bias. Under ideal conditions, we show that this out-of-equilibrium system ca

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

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

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

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

Radiation Safety and Society: Building Sweden’s Interdisciplinary Capacity for Nuclear Futures Energy production based on fission is complex, and safety aspects for workers, for the general public and for the environment are crucial, both to fulfil regulatory requirements and for the societal acceptance of the technology. We bring together researchers from four faculties at Lund University (Scienc

Kärnmagnetisk resonans, NMR, är en teknik som har många användningsområden, inte minst används NMR som en bildgivande teknik för diagnostisering av skador och sjuk- domar, vilket görs med så kallade MR-kameror. Med hjälp av diffusions-NMR kan man mäta vattenmolekylers rörelse, d.v.s. vattnets diffusion. Diffusions-NMR gör det möjligt att mäta hur långt vattenmolekylerna rör sig i olika riktningar.

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

I play cement Halla Steinunn Stefánsdóttir ‘I play cement’ (2019) is an audio and video installation for a screen and eight speakers. The footage was filmed and recorded in summer and winter 2017-18 as I navigated through a cement factory, situated by the mouth of Elliðaár in Reykjavík, Iceland. The work was later created at Lund University’s Inter Arts Center in Malmö, Sweden. ‘I play Cement’ con

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
