Dynamics of quantum correlations in four-qubit XXZ Heisenberg model with external magnetic field
Results in PhysicsIn this paper we argue about the quantum correlation (quantum entanglement and geometric quantum discord) in four-qubit XXZ Heisenberg Model. Here, the influence of uniform magnetic field on the dynamics of quantum correlation in cases of the ...

Identification and Reversible Optical Switching of NV+ Centers in Diamond
Advanced Functional Materials, EarlyView.NV+ centers in diamond are predicted to coexist with NV0 and NV– centers, but direct experimental confirmation remains challenging. Using positron annihilation spectroscopy with in situ light illumination, a charge transition NV+/0 is observed at 1.234(8) eV.

Quantum Coherence and Quantum Correlations
, 2017 We demonstrate a new type of optical coherence tomography (OCT) scheme based on ideas put forward by Mandel's group in 1991, curiously the same year than the first OCT scheme was demonstrated. It involves the measurement of the first-order correlation function (G(1)) between two beams that never interact with the sample under study.

Advanced Functional Materials, EarlyView.Heterojunctions combining halide perovskites with low‐dimensional materials enhance optoelectronic devices by enabling precise charge control and improving efficiency, stability, and speed. These synergies advance flexible electronics, wearable sensors, and neuromorphic computing, mimicking biological vision for real‐time image analysis and intelligent

Advanced Functional Materials, EarlyView.A spin group (SG)‐based mechanism is proposed to realize a single pair of Weyl points. PT‐symmetric nodal lines (NLs) persist under T‐breaking, protected by the combination of SG and P symmetry. When considering spin‐orbit coupling, the SG‐protected NL will split into Weyl points, which will also induce anomalous transport phenomena arising from ...

Engineering Strategies for 2D Layered Tin Halide Perovskite Field‐Effect Transistors
Advanced Functional Materials, EarlyView.2D halide perovskites are promising candidates for field‐effect transistor (FET) applications due to their high stability and suppressed ion migration in the presence of bulky organic spacers. This review systematically summarizes the optimization engineering strategies of 2D perovskite FETs and future challenges, which provide guidance for developing ...
