The Super-FRS (Superconducting FRagment Separator) at FAIR is a two-stage in flight separator, which aims to produce rare isotopes of all elements up to Uranium and separate them spatially within a few hundred nanoseconds so that a study of very short lived nuclei can be performed efficiently. In total, it is required to construct 24 dipoles and 170 multipole magnets (quadrupole, sextupole, octupole and steering dipole). [...]

Two samples of the Nuclotron CORT cable were manufactured and tested for their magnetization loss. The cables were designed to have a critical current of 1350 A at 77.3 K and around 10 kA at 4.2 K. [...]

After the Parallelism TS 2 was published in 2018, data-parallel types (simd<T>) have been implemented and used. Now there is sufficient feedback to improve and merge Section 9 of the Parallelism TS 2 into the IS working draft..

Detection of weak electromagnetic waves and hypothetical particles aided by quantum amplification is important for fundamental physics and applications. However, demonstrations of quantum amplification are still limited; in particular, the physics of quantum amplification is not fully explored in periodically driven (Floquet) systems, which are generally defined by time-periodic Hamiltonians and enable observation of many exotic quantum phenomena such as time crystals. [...]

We summarize the discussions at a virtual Community Workshop on Cold Atoms in Space concerning the status of cold atom technologies, the prospective scientific and societal opportunities offered by their deployment in space, and the developments needed before cold atoms could be operated in space. The cold atom technologies discussed include atomic clocks, quantum gravimeters and accelerometers, and atom interferometers. [...]

In this work we consider the axial-vector form factors of the nucleon in flavor-SU(2) and of the baryon octet in flavor-SU(3) Chiral Perturbation Theory. We include the Δ-isobar and the baryon decuplet as explicit degrees of freedom and focus on their consistent treatment in terms of chiral power counting. [...]
