COEXISTENCE OF QUANTUM THEORY AND SPECIAL RELATIVITY IN SIGNALING SCENARIOS 信号场景中量子理论和狭义相对论的共存

The coexistence between Quantum Mechanics and Special Relativity is usually formulated in terms of the no-signaling condition. Several authors have even suggested that this condition should be included between the basic postulates of Quantum Theory. However, there are several scenarios where signaling is, in principle, possible: based on previous results and the analysis of the relation between unitarity and signaling we present an example of a two-particle interferometric arrangement for which the dynamics is, in principle, compatible with superluminal transmission of information. This type of nonlocality is not in the line of Bell’s theorem, but closer in spirit to the one-particle acausality studied by Hegerfeldt and others. We analyze in this paper the meaning of this non-locality and how to preserve the coexistence of the two fundamental theories in this signaling scenario.
量子力学和狭义相对论的共存通常是用无信号条件来表述的。一些作者甚至建议,这个条件应该包括在量子论的基本公设之间。然而,在一些情况下,信号在原则上是可能的:基于先前的结果和对统一性和信号之间关系的分析,我们提出了一个两粒子干涉排列的例子,其动力学原则上与信息的超光速传输兼容。这种类型的非定域性不符合贝尔定理,但在精神上更接近于Hegerfeldt和其他人研究的单粒子因果性。本文分析了这种非定域性的含义,以及如何在这种情况下保持两种基本理论的共存。

DE BROGILE WAVES AND PSEUDOTACHYONIC RELATIVITY 德布罗吉尔波与伪音速相对论

尽管有作者,普通粒子(慢速)的德布罗意波通常被认为没有物理意义,主要是因为它们是快速的。我重新审视了德布罗意的一些原始想法,并讨论了解决这个问题的标准方法,即与德布罗意波重叠的“波包”。利用伪速子理论,很容易得出结论,这种速子波确实存在,但可能只有在与它相关的粒子速度相同的情况下才能被探测到。此外,就“二象性”而言,波和粒子似乎不是同一事物的两个方面,而是两个不同但密切相关的实体。这些反思涉及到德布罗意波的物理性质,包括粒子的“内部振动”,并导致了一个新的一般场论的前提。包括正极和负极

VACUUM MODIFIED GRAVITY AS AN EXPLANATION FOR FLAT GALAXY ROTATION CURVES 真空修正了引力,解释了平坦的星系旋转曲线
Pub Date : 2007-12-07 DOI: 10.2478/v10005-009-0003-4
R. V. Nieuwenhove
A theory is proposed which allows explaining the observed flat galaxy rotation curves, without needing to invoke dark matter. Whereas other theories have been proposed in the past which realize the same, the present theory rests on basic physical principles, in contrast to for instance the MOND theory. The key to arrive at this new theory is to consider from the start the energy density of the vacuum. The way to calculate the eect of the corresponding vacuum pressure on a mass has previously been laid down by Van Nieuwenhove (1992). We obtain a modification of Newton’s law of gravitation with some peculiar properties such as the occurrence of regions of repulsive gravity. The theory can make detailed predictions about galaxy rotation curves and is also able to explain to the Pioneer anomaly.
提出了一种理论,可以解释观测到的平坦星系旋转曲线,而不需要援引暗物质。过去已经提出的其他理论也实现了同样的目标,而现在的理论则建立在基本的物理原理上,与MOND理论形成对比。得出这个新理论的关键是从一开始就考虑真空的能量密度。计算相应的真空压力对质量的影响的方法已经由Van Nieuwenhove(1992)提出。我们得到了牛顿万有引力定律的一个修正,它具有一些特殊的性质,例如出现了排斥引力的区域。该理论可以对星系旋转曲线做出详细的预测,也可以解释先驱者号的异常。

COMPLEMENTARY SPECIAL RELATIVITY THEORY AND SOME OF ITS APPLICATIONS 互补狭义相对论及其一些应用
Pub Date : 2007-12-01 DOI: 10.2478/V10005-007-0027-6

This article introduces a mathematical model for the Complementary Special Relativity Theory (CSRT) in relation to Einstein’s Special Relativity Theory (SRT). The CSRT is technically derived following criterion of the logical independence of the Einstein’s postulates. The epithet ”Complementary” was selected in order to distinguish the CSRT theory from alternative theories. The mission of the CSRT is not to replace the Einstein’s Special Relativity. Both of them must coexist and must have physical applications. Forasmuch as the CSRT postulates do not embody constant velocity of the light by the Einstein’s way, the CSRT need not have 4-dimensional symmetry of the Lorentz and Poincare group. Existence of the CSRT transverse Doppler eect formula and the time dilation formula for moving clocks, which are different from Einstein’s, are crucial moments of the new theory. Moreover, the article demonstrates some physical applications of the CSRT on the John D. Anderson’s discovery of a quasi
本文介绍了与爱因斯坦狭义相对论(SRT)相联系的互补狭义相对论(CSRT)的数学模型。CSRT在技术上是根据爱因斯坦公设的逻辑独立性标准推导出来的。选择“互补”一词是为了将CSRT理论与替代理论区分开来。CSRT的任务不是取代爱因斯坦的狭义相对论。两者必须共存,并且必须有物理应用。由于CSRT假设不以爱因斯坦的方式体现光速恒定,CSRT不需要具有洛伦兹群和庞加莱群的四维对称性。与爱因斯坦不同的CSRT横向多普勒效应公式和运动时钟的时间膨胀公式的存在,是新理论的关键时刻。此外,本文还论证了CSRT在John D. Anderson发现一个拟粒子上的一些物理应用

We propose a binomial form of the interaction of an electron and a proton and study the classical solution of the Kepler problem and the scattering of electrons by protons. The derived formulas allow one to calculate the deflection angles and the trajectories of motion of electrons with energies from several eV to hundreds of MeV with impact parameters up to 10 13 cm.

After a first article on the subject, we begin by studying the pseudotachyonic transformation for energy, linear momentum and mass.

Dirac formulation of open relativistic strings as systems with constraints is made explicitly. Classical theory is given in the standard light-cone and covariant center-of-mass gauges. It is mentioned that the well-known result D = 26 is affected by using the standard quantization of the mutually independent nonphysical boson creation and annihilation operators. It is shown that in the Dirac formulation these operators are not independent in both the gauges. Concepts of Physics, Vol. IV, No. 4 (2007) DOI: 10.2478/v10005-007-0023-x 487 We give some new conditions on these operators and show that the theory is consistent with Poincare algebra in any dimension D. 488 Concepts of Physics, Vol. IV, No. 4 (2007) Dirac Formulation of Free Open String 1 Hamilton description of classical open string We will study the Nambu–Goto [1] free open string in dimension D.

The classical string is described by Lagrangian L(X) = −ω ∫ π 0 Ldσ, where ω > 0 is a constant and the Lagrangian density L(τ, σ) is L = √( ẊX ′ )2 − (Ẋ)2(X ′)2 . A dot means partial derivation with respect to τ , a dash with respect to σ, and XY = gμνXY ν = XμY ν . The boundary conditions are X ′ μ(τ, 0) = X ′ μ(τ, π) = 0.

Concepts of Physics, Vol. IV, No. 4 (2007) DOI: 10.2478/v10005-007-0023-x 487 We give some new conditions on these operators and show that the theory is consistent with Poincare algebra in any dimension D. 488 Concepts of Physics, Vol. IV, No. 4 (2007) Dirac Formulation of Free Open String 1 Hamilton description of classical open string We will study the Nambu–Goto [1] free open string in dimension D. We assume the sign convention gμν = diag(−1, 1, . . . , 1), where μ, ν = 0, 1, . . . , D − 1. The string is described by the functions X(τ, σ), where τ ∈ R and σ ∈ 〈0, π〉. The classical string is described by Lagrangian L(X) = −ω ∫ π 0 Ldσ, where ω > 0 is a constant and the Lagrangian density L(τ, σ) is L = √( ẊX ′ )2 − (Ẋ)2(X ′)2 . A dot means partial derivation with respect to τ , a dash with respect to σ, and XY = gμνXY ν = XμY ν . The boundary conditions are X ′ μ(τ, 0) = X ′ μ(τ, π) = 0. In the Hamiltonian formulation we define momenta Pμ(τ, σ) = δL δẊμ(σ) = ω Ẋμ(X ′X ′)−X ′ μ(ẊX ′) √( ẊX ′ )2 − (Ẋ)2(X ′)2 . (1) From (1) we obtain the relations Φ1 = 1 2 ( P 2 + ω ( X ′ )2) = 0 , Φ2 = PX ′ = 0 (2) called constraints. For the Poisson brackets of two functionals F (X,P ) and G(X,P ) we have { F,G } = ∫ π 0 ( δF δXμ(σ) δG δPμ(σ) − δF δPμ(σ) δG δXμ(σ) ) dσ . (3) In particular, the relation { X(σ), P ν(σ′) } = gδ(σ − σ′) is valid. The Hamiltonian of the system with constraints (2) is","PeriodicalId":249199,"journal":{"name":"Old and New Concepts of Physics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116706575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
