Stark anti-crossing (SAC) serves as a new approach to switch the Kerr birefringence effect of the off-centered core-shell square nanowires (OSN). The intensity of SAC induced by an electric field is inversely correlated with the degree of the core displacement from the center. To the best of our knowledge, it is the first demonstration that SAC is equipped with efficacy in suppressing Kerr birefringence of OSN by intensifying energy degeneracy and mitigating the parity symmetry distortion of wavefunction due to core displacement. Such a novel mechanism lies in the formation of two quasi-degenerate energy levels with nearly identical energies but opposite parity wavefunctions. It demonstrates a transform from polarization-dependent to -independent response of refractive index changes at mid-infrared wavelengths longer than 10 µm.
斯塔克反交叉(SAC)是切换偏心核壳方形纳米线(OSN)的克尔双折射效应的一种新方法。电场诱导的 SAC 强度与磁芯偏离中心的程度成反比。据我们所知,这是首次证明 SAC 具有抑制 OSN 的克尔双折射的功效,它通过加强能量变性和减轻由于磁芯位移引起的波函数奇偶对称性失真来实现。这种新机制在于形成两个能量几乎相同但奇偶性波函数相反的准退化能级。在波长超过 10 微米的中红外波段,它展示了折射率变化从依赖偏振到不依赖偏振的转变。

Inorganic fluoroperovskite materials are increasingly important in solar technology due to their exceptional structural, optical, electronic, and mechanical properties. This study uses DFT calculations to investigate the properties of Mg3PF3 fluoroperovskite. Our results show a crystal structure and lattice parameter of (a = 4.64 Å) which align with previous theoretical and experimental findings, confirming the accuracy of our calculations. Mechanical analysis reveals that Mg3PF3 is naturally ductile, elastically anisotropic, and stable according to established criteria. The band structure and PDOS indicate that it is a semiconductor with direct bandgap of 3.88 eV at the Γ point, making it suitable for electronic applications. Electron charge density mapping suggests a predominantly ionic bonding nature. Optical property analysis shows significant dielectric constant peaks in the photon energy range favorable for solar cells. Overall, these findings position Mg3PF3 as a promising candidate for solar cell technology, highlighting its potential for enhancing renewable energy solutions.

Atmospheric turbulence and obstacles can distort rays during transmission, resulting in significant wavefront distortion and loss of optical field information. This paper employs the phase screen method to simulate the transmission characteristics of a Gaussian plane wave in turbulent conditions, establishing an obstacle grid at the receiver to represent beam obstruction. A dataset of unobstructed transmissions is used to train a Backpropagation Neural Network, constructing neurons and connection weights. By scanning optical field data systematically, the model compensates for the obstructed portions of the optical field distribution. The results are compared to unobstructed transmissions, focusing on image similarity, and demonstrate the entire process from compensation to distortion correction. Simulation results indicate that the Backpropagation Neural Network effectively compensates for optical field information loss, showcasing strong performance within a certain time scale.

The nonlinear Schrödinger equation (NLSE) and its various forms have significant applications in the field of soliton theory. The Fokas-Lenells (FL) equation stands as a cornerstone in deepening our understanding of nonlinear wave dynamics within optical systems, particularly concerning the behavior of ultrashort pulses across different media. Its significance lies in providing a comprehensive framework to study and analyze complex phenomena, ultimately contributing to advancements in optical technology and applications. The FL equation is an integrable extension of the NLSE that provides a description of the nonlinear propagation of pulses in optical fiber. This paper seeks to discover optical soliton solutions for the FL equation by employing a modified sub-equation method. Additionally, the sensitivity analysis is described by using the various initial conditions. The main novelty of this paper lies in conducting a sensitivity analysis of the FL equation by examining the effects of various initial conditions, providing deeper insights into how these conditions influence the behavior of soliton solutions. For the physical behavior of the models, some solutions are graphically shown in 2D, 3D, and contour graphs by assigning specific values to the parameters under the provided situation at each solution. As a result, we discovered several new families of exact traveling wave solutions, such as bright solitons, dark solitons, and combined bright and dark solitons. This research opens numerous avenues for further exploration in the field of nonlinear wave dynamics and optical soliton theory. The discovery of exact soliton solutions for the FL equation through a modified sub-equation method paves the way for deeper investigations for newcomer researchers. The results of this study will contribute further to the field of mathematical physics, particularly in enhancing the understanding of nonlinear wave propagation and soliton theory in optical and other physical systems.
非线性薛定谔方程(NLSE)及其各种形式在孤子理论领域有着重要的应用。福卡斯-勒内尔斯(FL)方程是加深我们对光学系统内非线性波动力学理解的基石,特别是关于超短脉冲在不同介质中的行为。它的意义在于为研究和分析复杂现象提供了一个全面的框架,最终促进了光学技术和应用的进步。FL 方程是 NLSE 的可积分扩展,描述了脉冲在光纤中的非线性传播。本文试图采用一种改进的子方程方法来发现 FL 方程的光学孤子解。此外,本文还利用各种初始条件进行了敏感性分析。本文的主要创新之处在于通过研究各种初始条件的影响来对 FL 方程进行灵敏度分析,从而更深入地了解这些条件如何影响孤子解的行为。对于模型的物理行为,通过为每个解在所提供情况下的参数赋予特定值,以二维、三维和等值线图的形式展示了一些解。结果,我们发现了几个新的精确行波解系列,如亮孤子、暗孤子以及亮暗结合孤子。这项研究为进一步探索非线性波动力学和光学孤子理论领域开辟了众多途径。通过改进的子方程方法发现了 FL 方程的精确孤子解,为新手研究人员进行更深入的研究铺平了道路。这项研究的成果将进一步促进数学物理领域的发展,特别是加深对光学和其他物理系统中非线性波传播和孤子理论的理解。

Quantum Dots, due to their fully quantized electronic states, have contributed to considerable progress in modern science and technology. Here we calculate the wave functions and energy spectrum of an electron confined in an oblate spheroidal quantum dot under the finite barrier potential condition, allowing the tailoring of the various energy states for specific applications. By calculating the electron wave functions outside the dot, we found that an infinite barrier is not a valid approximation for analyzing the optical properties of the structure. The effect of various geometrical and electrical characteristics of the structure, including the eccentricity, effective volume, and the height of barrier potential, is investigated. Additionally, the findings are compared with those found with prolate spheroidal quantum dot. The findings are further validated by comparing them to the exact electron energy level in a spherical quantum under the infinite barrier approximation.

Regulation of CN-related optical transitions and non-radiative capture cross-section by biaxial strain in AlN 氮化铝中双轴应变对 CN 相关光学转变和非辐射俘获截面的调控

Carbon-related 4.7 eV absorption band and small in-plane strains in AlN may have some significant effects on its application in optoelectronic devices. Based on the accurate hybrid density functional calculation, we investigate the transition energy levels, photo-transition processes, and hole capture cross-sections of CN defect. We propose that the transition from −1 to 0 charge states of CN defect may be responsible for the 4.7 eV absorption band in AlN. In addition, the CN defect-related absorption and emission peaks are linearly dependent on the biaxial strain in the range of −3% to +3%, and the hole non-radiative capture rate by the CN center at the −3% biaxial strain is only 3.65% of that at the +3% biaxial strain. This work provides an effective approach for regulating the charge carrier capture ability of the defect center and improving device performance.

Cu2MoSnS4 (CCTS) is well suited as the absorption layer for solar cell due to its high absorption coefficient, suitable optical bandgap, and good stability. In this study, a novel CCTS-based solar cell with the structure of FTO/ZnO:Al/Ag2S/CCTS/Cu2O/C was proposed by setting Cu2O as the hole transport layer (HTL) to boost the photovoltaic (PV) efficiency. A comparative numerical study of its PV performance with that of the reference counterpart was performed by employing the software SCAPS, which demonstrates its obvious advantage. It was also numerically optimized by tuning the geometry and optoelectronic parameters. The optimized power conversion efficiency (PCE) was revealed to reach 26.27 %, getting 135 % improvement compared with that of the reference counterpart.

Imaginary numbers play a significant role in quantum mechanics. Recently, a rigorous resource theory for the imaginarity of quantum states were established, and several imaginarity measures were proposed. In this work, we propose a new imaginarity measure based on the Tsallis relative entropy. This imaginarity measure has explicit expression, and also, it is computable for bosonic Gaussian states.
虚数在量子力学中发挥着重要作用。最近,人们建立了量子态虚数的严格资源理论,并提出了几种虚数度量方法。在这项工作中,我们提出了一种基于 Tsallis 相对熵的新意象度量。这种意象度量有明确的表达式,而且对于玻色高斯态是可计算的。

A quadrupole oscillator as an integrable model 作为可积分模型的四极振荡器
IF 2.3 3区 物理与天体物理 Q2 PHYSICS, MULTIDISCIPLINARY Pub Date : 2024-11-05 DOI: 10.1016/j.physleta.2024.130032

A quadrupole oscillator is presented as an integrable model in the Born-Oppenheimer formalism with an electronic Hamiltonian being the quadrupole tensor. The electronic states of present concern are associated with a doubly degenerate positive eigenvalue of the electronic Hamiltonian, and accordingly the nuclear Hamiltonian takes a 2×2 matrix form. While the potential function for nuclear motion is proportional to r2, the kinetic energy operator is rather complicated, containing coupling terms with a Berry connection through adiabatic approximation. The energy eigenvalues, which receive a modification by a Chern number, get closer to those for the 3D isotropic harmonic oscillator if the angular momentum quantum number becomes sufficiently large.
在玻恩-奥本海默形式主义中,四极振荡器是一个可积分模型,其电子哈密顿是四极张量。目前关注的电子态与电子哈密顿的双变性正特征值有关,因此核哈密顿采用 2×2 矩阵形式。核运动的势函数与 r2 成正比,而动能算子则相当复杂,通过绝热近似,包含了与贝里联系的耦合项。如果角动量量子数变得足够大,能量特征值就会变得更接近三维各向同性谐振子的能量特征值。
