The formation of matter structures in the Universe   总被引:2,自引:0,他引:2  
陶必修 《中国物理》2002,11(3):238-240
We discuss the formation of matter structures in the Universe,and show that spherical Higgs bosonic membranes were possibly produced homogeneously in the early Universe and expanded rapidly.After a period of evolution,the composition of the membranes began to change,the massive particles replaced the imaginary Higgs bosons through the Higgs mechanism,while the energy came from the Universe expansion.After that,the membranes reduced their speed and broke into pieces,which became the seeds of matter structures.It is proven that microscopic principles may affect the formation of large-scale structures,and the formation of structures such as cosmic foam is also possible.  相似文献

A new energy source originating from extra dimensions   总被引:1,自引:0,他引:1  
陶必修  吉世印  李芳琼 《中国物理》2004,13(11):1830-1834
In this work the Einstein gravitational field equations and the Lichnerowicz boundary formalism in the extra dimensions are used to build up our black hole model from 6-dimensional space-time. From the internal stress-energy tensor the solutions with energy levels and semiclassical space-quantization are obtained, which combines with only one metric condition outside the defect. We show a new type of energy source, which originates from extra dimensions. A part of the energy source of quasi-stellar object (QSO) maybe come from extra dimensions in that way. The theoretical arithmetic upper limit is identical to that of the output energy of QSO.  相似文献

微观数字态     
当组成电子系统的元件或神经系统的细胞的尺度(或其间隙)缩至纳米量级以下时,量子规律必然要起作用.在这种超微结构中表达的一个二进制数,就相当于系统的一个微观态,这些微观态的复杂性由二进制数的位数确定.从不同形式的不对易代数,可得到微观数字态的不同表示,反映了理论上量子规律的多样性.要选择合适的不对易代数,必须通过实验才能获得.另外,把“拟荷”这个抽象概念与微观体系的能级联系起来,使之成为可观测的物理量,从而可应用物理方法对微观数字系统进行定量分析.  相似文献

The existence and evolution of spherical membrane configurations in spherical-symmetric and self-similar spacetimes are studied, and a solution for the dynamics of membranes is obtained. A new interpretation for the origin and evo lution of the cosmic matter-structures is acquired. It agrees well with the survey of astronomy.  相似文献

The dynamics of planar relativistic domain walls is investigated with the help of a new method proposed by Arodz and Larsen. Two solutions are found: one is a steady state domain wall, the other is a nonstationary domain wall. They move with the same constant velocity in the laboratory frame coordinates. When the velocity approaches light velocity c, the "width" of the nonstationary wall inflates very slowly. These domain walls can disappear again soon after their creation in the early universe by moving away from our visible universe. So they would not dominate the universe completely, but keep the observed universe approximately isotropic and homogeneous.  相似文献

Some aspects of two-dimensional gravity coupled to nonstationary Higgs field solitons are examined.General properties of the nonstationary Higgs field model in flat space-time and their generalization to curved space-time are discussed.A solution which corresponds to cosmology is arrived at.  相似文献
