De Broglie Matter Waves from the Linearized Einstein Field Equations

We suggest a connection between matter waves and gravitational waves. We find solutions of the linearized Einstein field equations in the form of de Broglie waves. These therefore acquire a new geometrical meaning.     

An experiment to test the reality of de Broglie waves

A second-order interferometric experiment in which de Broglie waves pass through a set of beamsplitters and progressively lose intensity, leading to a decrease in the visibility, is presented. On the contrary, since the intensity reduction is the same in the two overlapping waves, quantum mechanics predicts a constant visibility.     

非阿贝尔腔量子电动力学模型下偏振光场的影响

通过使用场正交算符,而不是传统的玻色算符,研究了非阿贝尔腔量子电动力学(QED)模型中原子和偏振光场的相互作用。讨论了初始双模偏振光场对于原子布居数反转以及偏振光场的压缩特性的影响。结果表明,原子布居数反转的演化不仅与偏振椭圆的相位角有关,也与偏振椭圆的椭率角有关;只有当偏振椭圆是右旋圆偏振光时,原子布居数反转随时间的演化基本不变,趋近于初始值0,而当偏振椭圆是左旋圆偏振光时,原子布居数反转随时间的演化呈现周期性的崩塌复苏变化。另外,当初始光场是左旋圆偏振光时,光场可以出现周期性的压缩;而当初始光场是右旋圆偏振光时,光场的压缩不会持续出现。     

Non-Local Interferometry: A Causal Explanation by Means of Local Wavelet Analysis

In the following we consider the possibility of interpretating recent non-local interferometric experiments according to the De Broglie causal model. With the help of a simplified mathematical model based on wavelet analysis it is indeed possible to explain it in a causal way. Furthermore we show the distinctions between the two formalisms and discuss some experimental conditions that may make these differences evident.     

有机电致发光器件量子效率测量系统的建立及其应用研究

有机电致发光器件（OLED）的量子效率是衡量器件发光性能的一个非常重要的参数，考虑到提高OLED量子效应的基本前提是能精确测得器件的量子效率。本文工作采用美国Keithley公司的系列产品，设计与组建了一套精确测量OLED量子效率的测量系统（主要由真空系统和测试系统组成）。应用本系统测量时，由测量软件通过数据采集卡来实时地对K－2400（稳压源）和K－485（微检流计）进行控制，得到流经器件的电流和器件输的光电流，再经过换算得出注入器件的电子数和从器件输出的光子数，从而能够得到器件的量子效率值，最后由计算机动态地绘制出器件的性能曲线。此外，我们还利用本测量系统对以MEH－PPV为基质的橙红色OLED进行测量，该测试样品在0.0117A/cm^2的电流密度下，测量量子效率为0．39％。

Exact Solvability and Quantum Integrability of a Derivative Nonlinear Schrödinger Model

Using a variant of quantum inverse scattering method (QISM) which is directly applicable to field theoretical systems, we derive all possible commutation relations among the operator valued elements of the monodromy matrix associated with an integrable derivative nonlinear Schrödinger (DNLS) model. From these commutation relations we obtain the exact Bethe eigenstates for the quantum conserved quantities of DNLS model. We also explicitly construct the first few quantum conserved quantities including the Hamiltonian in terms of the basic field operators of this model. It turns out that this quantum Hamiltonian has a new kind of coupling constant which is quite different from the classical one. This fact allows us to apply QISM to generate the spectrum of quantum DNLS Hamiltonian for the full range of its coupling constant.     

What Can the Quantum Liquid Say on the Brane Black Hole, the Entropy of an Extremal Black Hole, and the Vacuum Energy?

Using quantum liquids one can simulate the behavior of the quantum vacuum in the presence of the event horizon. The condensed matter analogs demonstrate that in most cases the quantum vacuum resists formation of the horizon, and even if the horizon is formed different types of the vacuum instability develop, which are faster than the process of Hawking radiation. Nevertheless, it is possible to create the horizon on the quantum-liquid analog of the brane, where the vacuum life-time is long enough to consider the horizon as the quasistationary object. Using this analogy we calculate the Bekenstein entropy of the near-extremal and extremal black holes, which comes from the fermionic microstates in the region of the horizon—the fermion zero modes. We also discuss how the cancellation of the large cosmological constant follows from the thermodynamics of the vacuum.     

Polarization States of Light and Their Quantum Tomography

The notion and main features of polarization states of light are discussed within the framework of classical and quantum optics. This notion is shown to be correctly defined for arbitrary light beams only within quantum optics by using the P-quasispin formalism developed earlier. Polarization states of quantum light are shown to be fully described by a polarization density operator (PDO) obtained via reducing the total field density operator. Theoretical foundations are given for quantum tomography of polarization states of light fields considered as a way of measuring PDO. Herewith, the main attention is paid to a method where proper polarization tomographic observables (PDO “measurers”) are used. The method is shown to be adequately formulated by means of quasi-spectral tomographic expansions of PDO in special operator bases (given by finite sums of partially orthogonal projectors), which determine probability distributions of tomographic observables as expansion coefficients. Matrix versions of such “tomographic” PDO representations are obtained. In particular, projections of these expansions on quasiclassical operator bases, determining polarization quasiprobability functions, are given. An example of experimental implementation of polarization tomography of unpolarized light (biphoton radiation with hidden polarization) is analyzed.

Dynamical Analysis and Exact Solutions of a New (2+1)-Dimensional Generalized Boussinesq Model Equation for Nonlinear Rossby Waves*

In this paper, we study the higher dimensional nonlinear Rossby waves under the generalized beta effect. Using methods of the multiple scales and weak nonlinear perturbation expansions [Q. S. Liu, et al., Phys. Lett. A 383 (2019) 514], we derive a new $(2+1)$-dimensional generalized Boussinesq equation from the barotropic potential vorticity equation. Based on bifurcation theory of planar dynamical systems and the qualitative theory of ordinary differential equations, the dynamical analysis and exact traveling wave solutions of the new generalized Boussinesq equation are obtained. Moreover, we provide the numerical simulations of these exact solutions under some conditions of all parameters. The numerical results show that these traveling wave solutions are all the Rossby solitary waves.
