Room Temperature Evidence of PtTe2 Topological Semimetal Character
physica status solidi (RRL) – Rapid Research Letters, EarlyView.We report on a melt growth process for the synthesis of high‐quality PtTe2 crystals, as assessed by X‐ray diffraction and X‐ray photoemission spectroscopy characterization. By angle‐resolved photoemission spectroscopy investigation, we observe the expected topological features at cryogenic temperature and we demonstrate their stability even at room ...

Digital Twin Simulations Toolbox of the Nitrogen‐Vacancy Center in Diamond
Advanced Quantum Technologies, EarlyView.The Nitrogen‐vacancy (NV) center in diamond is a key platform within quantum technologies. This work introduces a Python based digital‐twin of the NV, where the spin dynamics of the system is simulated without relying on commonly used approximations, such as the adoption of rotating frame. The digital‐twin is validated through three different examples,

Bell inequalities with Orbital Angular Momentum of Light
, 2012 We shall present a theoretical description of paraxial beams, showing the propagation modes that arise from the solution of the paraxial equation in free space. We then discuss the angular momentum carried by light beams, with its decomposition in spin and orbital angular momentum and its quantization.

Orbitally Driven Anomalous Thermal Transport Under High Pressure in Gallium Nitride
Rare Metals, EarlyView.ABSTRACT Extreme conditions such as high pressure offer opportunities for innovative materials design and applications. For over a century, studies on thermal transport in crystals under high hydrostatic pressure have shown that lattice thermal conductivity generally exhibits a monotonic increase with pressure.

Tunable Colloidal Synthesis Enabling μ‐ARPES on Individual Bismuth Nanocrystals
Small, EarlyView.We report a highly controlled colloidal synthesis of Bi nanosheets with tunable lateral sizes (0.6–4.1 µm), hexagonal shape, and a layered single‐crystalline structure along the {00l} planes. The nanosheets feature high phase purity and excellent ambient stability. Remarkably, O2 promotes larger lateral growth with ultra‐smooth surfaces. This scalable,

Small Structures, EarlyView.The article presents a benchmark study using state‐of‐the‐art high‐level ab initio methodologies to predict infrared and Raman frequencies of subnanometric metal clusters. The importance of characterizing conical intersections in their potential energy landscapes is also highlighted, with the associated (Pseudo‐)Jahn–Teller distortions of cluster ...
