The C–H functionalization of inert alkanes has long been one of the most challenging reactions in organic synthesis. Now, the use of hypervalent iodine reagents has enabled the diverse functionalization of various aliphatic C–H bonds under blue light irrad ...
This study analyzes the linguistic rhetorical strategies utilized by the German-speaking Querdenken movement's alternative media during the COVID-19 pandemic. Employing a critical discourse analysis (CDA) framework, we examine articles from alternative med ...
Our motivation in this paper is twofold. First, we study the geometry of a class of exploration sets, called exit sets, which are naturally associated with a 2D vector-valued Gaussian Free Field: ϕ:Z2→RN, N≥1. W ...
The analysis of the acceleration behavior of gradient-based eigensolvers with preconditioning presents a substantial theoretical challenge. In this work, we present a novel framework for preconditioning on Riemannian manifolds and introduce a metric, the l ...
We present a numerical implementation, based on Wannier interpolation, of a Kubo-Greenwood formalism for computing the spatially dispersive optical conductivity in crystals at first order in the wave vector of light. This approach is more efficient than di ...
Neural networks have shown to be a powerful tool to represent the ground state of quantum many-body systems, including fermionic systems. However, efficiently integrating lattice symmetries into neural representations remains a significant challenge. In th ...
Building on recent advances of the embedded cluster approach combined with multiconfigurational theory, this work investigates the electronic states in thorium-doped CaF2 crystals. Th:CaF2 is established as a promising material for solid-state nuclear cloc ...
Six C-even states, denoted as X, with quantum numbers J(PC) = 0(-+), 1(++), or 2(++), are searched for via the e(+)e(-) -> gamma(DsDs*-/+)-D-+/- process using (1667.39 +/- 8.84) pb(-1) of e(+)e(-) collision data collected with the BESIII detector operating ...
Feynman diagrams (notably the triangle diagram) involving heavy enough particles contain branch cuts on the physical sheet-anomalous thresholds-which, unlike normal thresholds and bound-state poles, do not correspond to any asymptotic n-particle state. "Wh ...
Six-coordinate chromium(iii) complexes with high spin-flip (SF) photoluminescence quantum yields and lifetimes (molecular rubies) have attracted huge interest in the past years due to their applicability in sensing, photocatalysis or circularly polarised e ...
The extraordinary properties of the Kitaev model have motivated an intense search for new physics in materials that combine geometrical and bond frustration. In this Letter, we employ inelastic neutron scattering, spin wave theory, and exact diagonalizatio ...
The restricted Siegel disc is a homogeneous space related to the con- nected component To(1) of the universal Teichmller space via the period mapping. In this paper, we show that it is a coadjoint orbit of the universal central extension of the restricted ...
Using data samples with an integrated luminosity of 4.5 fb(-1) collected by the BESIII detector at center-of-mass energies ranging from 4.66 GeV to 4.95 GeV, we study the processes of e(+) e(-) -> omega X(3872) and e(+) e(-) -> gamma X(3872). With the e(+) ...
We report the spectroscopic analysis of 10 satellite galaxy candidates in the sphere of influence of the Sombrero galaxy (M104, NGC4594), based on data obtained with IFUM (integral field units for Magellan). Based on their newly observed recessional veloci ...
Understanding and manipulating emergent phases, which are themes at the forefront of quantummaterials research, rely on identifying their underlying symmetries. This general principle has been particularly prominent in materials with coupled electronic and ...
Cryptographic voting protocols often rely on methods that require a large number of modular exponentiations. Corresponding performance bottlenecks may appear both on the server and the client side. Applying existing optimization techniques is often mention ...
