Optical Counterparts to X-ray sources in LSST DP1
We present a crossmatch between a combined catalog of X-ray sources and the Vera C. Rubin Observatory Data Preview 1 (DP1) to identify optical counterparts. The six fields targeted as part of DP1 include the Extended Chandra Deep Field South (E-CDF-S), the Euclid Deep Field South (EDF-S), the Fornax Dwarf Spheroidal Galaxy (Fornax dSph), 47 Tucanae (47 Tuc) and science validation fields with low galactic and ecliptic latitude (SV\_95\_-25 and SV\_38\_7, respectively). We find matches to 2314 of…

Simphony: A full tight-binding package for lattice vibrations and topological phonon analysis
Simphony is an open-source software package designed for the topological analysis of lattice vibrations based on Wannier tight-binding models. Its primary function is to classify the topology of novel materials by computing bulk and slab phonon band structures, extracting phonon surface spectra, and providing analysis tools such as Wilson loop calculations and Weyl node detection. The workflow is analogous to that of established electronic topology codes like Wannier90 and WannierTools. It also…

Huge respect for Andrea Sella. He's returned his Faraday prize to the Royal Society as protest against the Society's inaction over #ElonMusk. He joins Dorothy Bishop and Andrew Miller who resigned from the society.

Lise Meitner ist ein Beispiel dafür, wie schwer es Anfang unseres Jahrhunderts für Frauen war, die Hochschullaufbahn zu ergreifen. Ihre Schulausbildung war zunächst die damals für junge Mädchen aus gut bürgerlicher Familie übliche. Aber später bereitete sie sich doch durch Privatunterricht und für sich allein auf das Abiturientenexamen vor. Sie bestand es mit Auszeichnung. Dann studierte sie in Wien und war 1906 die zweite Frau, die als Physikerin an der Wiener Universität promovierte. Von Lise…

Role of topotactic hydrogen in Superconductivity of Infinite-layer Nickelate NdNiO$_{2}$: A first-principles and variational Monte Carlo study
Employing combination of first-principles calculations, low-energy model construction, and variational Monte Carlo solution of the ab-initio derived Hubbard model, we study the effect of hydrogenation in the electronic structure and superconducting properties of infinite-layer nickelate, NdNiO$_2$. We find that the introduction of hydrogen at the apical oxygen vacancy position strongly influences the Wannier function corresponding to the effective interstitial orbital at the Ni site bound to th…
