Abstract About 40 trans-Neptunian binaries (TNBs) have fully determined orbits with about 10 others being solved except for breaking the mirror ambiguity. Despite decades of study, almost all TNBs only ever been analyzed a model that assumes perfect Keplerian motion (e.g., two point masses). In reality, TNB systems are non-Keplerian due to nonspherical shapes, possible presence undetected system components, and/or solar perturbations. this work, we focus on identifying candidates detectable...
The open-source Python package diffpy.mpdf , part of the DiffPy suite for diffraction and pair distribution function analysis, provides a user-friendly approach performing magnetic (mPDF) analysis. builds on existing libraries in to allow users create models structures calculate corresponding one- three-dimensional mPDF patterns. can be used perform fits data either isolation or combination with atomic joint refinement structure. Examples are given using MnO MnTe as representative...
The chiral charge density wave material (TaSe${}_{4}$)${}_{2}$I contains a half-filled Ta $d$-orbital, which creates Weyl points in metallic band structure. However, historical measurements show insulating electrical transport. authors use single-crystal diffraction and transmission electron microscopy to that large single crystals have pristine chirality: they can exhibit enantiomer over millimeters. They resolve the contradiction transport by showing consistent iodine deficiency of more...
The quasi-one-dimensional chiral compound (TaSe$_4$)$_2$I has been extensively studied as a prime example of topological Weyl semimetal. Upon crossing its phase transition temperature $T_\textrm{CDW}$ $\approx$ 263 K, exhibits incommensurate charge density wave (CDW) modulations described by the well-defined propagation vector $\sim$(0.05, 0.05, 0.11), oblique to TaSe$_4$ chains. Although optical and transport properties greatly depend on chirality, there is no systematic report about domain...
