This study reports the detailed physical properties of high-quality RhGe and CoGe B20 single crystals, revealing their metallic, paramagnetic, and weakly correlated semimetal nature to establish a platform for investigating multifold fermions and helicoid-arc surface states in chiral topological semimetals.
This paper investigates the spectroscopic properties of a new -doped sesquisulfide single crystal, identifying 26 luminescence transitions across the 0.49 to 5.5 m range and confirming their assignments through theoretical calculations, thereby establishing the material as a promising low-phonon host for broad mid-IR laser applications.
This study reports the successful growth of undoped and Tl/In-doped bulk crystals via the miniaturised vertical Bridgman method, characterizing their structural homogeneity, congruent melting behavior, and enhanced luminescence properties that closely resemble their doped caesium iodide counterparts.
This study utilizes multi-dimensional photoemission spectroscopy and configuration-interaction analysis to demonstrate that LaCoO3 undergoes a thermally driven spin-state crossover from a predominantly low-spin ground state to a mixed low-spin/high-spin configuration, with Co 2p photoemission identified as a sensitive quantitative probe for tracking this transition.
This study reports the design and characterization of two new 2D layered hybrid perovskites, (C15H16N)2CdCl4 and ((Br)C15H15N)2CdCl4, which exhibit record-high photoluminescence quantum yields originating from their organic trans-stilbene cations, demonstrating their potential for efficient radiation detection and scintillation applications.
This study demonstrates that ion implantation induces a metal-insulator transition in epitaxial ScN thin films through a two-stage damage accumulation process involving isolated acceptor defects at low doses and carrier-localizing point defects at high doses, with the transition threshold and localization strength critically dependent on the initial film quality and substrate.
This paper develops a unified quantum master equation model to systematically analyze and compare the efficiency of microcavity OLEDs across weak and strong light-matter coupling regimes, aiming to identify the optimal strategy for overcoming performance limitations like efficiency roll-off.
This paper introduces a dynamic extension of the high-temperature expansion to accurately compute the dynamic structure factor for frustrated quantum spin systems, successfully benchmarking the method on various models and reproducing experimental data for the S=1 pyrochlore material NaCaNi2F7.
This paper extends high-temperature series expansions to dynamic Matsubara spin correlators for Heisenberg models, providing precomputed exact expansion coefficients up to the 12th order for arbitrary lattices to enable the calculation of static susceptibilities and real-frequency dynamic structure factors.
This paper presents a gauge-invariant theoretical framework to compute the average density of Bloch electrons in a homogeneous magnetic field up to second order, revealing that while the linear response for insulators follows the Streda formula, metals exhibit an additional Fermi-surface contribution from orbital magnetic moments, and the second-order response is significantly influenced by the quantum metric tensor generating a pseudo-magnetic moment.
