The technique of muon spin rotation (μSR) has emerged in the last few decades as one of the most powerful methods of obtaining local magnetic information. To make the technique fully quantitative, it is necessary to have an accurate estimate of where... Read More about DFT + μ: Density functional theory for muon site determination.

Comparing the hardness of MAX 2-SAT problem instances for quantum and classical algorithms (2023)
Journal Article

An algorithm for a particular problem may find some instances of the problem easier and others harder to solve, even for a fixed input size. We numerically analyze the relative hardness of MAX 2-SAT problem instances for various continuous-time quant...

Accretion disc coronae (ADC) sources are very high inclination neutron star or black hole binaries, where the outer accretion flow blocks a direct view of the central source. The weak observed X-ray emission is instead produced mainly by scattering o... Read More about A different view of wind in X-ray binaries: the accretion disc corona source 2S 0921-630.
