In collaboration with the Paul Scherrer Institute, the University of Cambridge and others, we've published a new paper in Physical Review Accelerators and Beams, reporting experimental results of a YBCO bulk superconducting undulator magnetic optimisation. The magnetic field optimisation of RE-Ba-Cu-O (REBCO, RE=rare earth) bulk superconducting undulators is a fundamental step toward their implementation in an accelerator driven photon source, like a synchrotron or a free electron laser. We propose a sorting algorithm to reduce the undulator’s phase error based on the reconstruction of the trapped current inside the bulks of a staggered array undulator. The results obtained with a YBCO short prototype field-cooled down to 10 K in a 10 T magnetic field are reported, which suggest a potential improvement in the homogeneity of the on-axis undulator field of a full scale prototype by more than an order of magnitude.

TMOS PAPER: Framework for engineering of spin defects in hexagonal boron nitride by focused ion beams by Igor Aharonovich and Milos Toth READ In: arXiv - Hexagonal boron nitride (hBN) is gaining interest as a wide bandgap van der Waals host of optically active spin defects for quantum technologies. Most studies of the spin-photon interface in hBN focus on the negatively charged boron vacancy (VB-) defect, which is typically fabricated by ion irradiation. However, VB- fabrication methods often lack robustness and reproducibility when applied to thin flakes (less than 10 nm) of hBN. Here we identify mechanisms that both promote and inhibit VB- generation and optimize ion beam parameters for site-specific fabrication of optically active VB- centers. We emphasize conditions accessible by high resolution focused ion beam (FIB) systems, and present a framework for VB- fabrication in hBN flakes of arbitrary thickness for applications in quantum sensing and quantum information processing.

The search and characterization of Weyl Semimetals (WSMs) is a challenge, in particular, because it requires a deep numerical analysis of the Fermi surface to identify the Fermi arcs. Here, we proposed a theoretical framework based on the combination of density functional theory with maximally localized Wannier functions for tight-binding parametrization and topological analyses to identify and characterize WSMs compounds. https://lnkd.in/gCN4YmTf

In the quest to solve the singularly perturbed delay differential equations (SPDDEs) involving large delay with integral boundary condition, the cubic spline in compression technique is explored for the study of dynamical systems to capture complex temporal phenomena in a wide range of scientific disciplines. The insights gained from this research paper provide a foundation for further exploration and utilization of SPDDEs in understanding and predicting the behavior of complex systems across diverse scientific domains.
