Stresses and strains in the first law for Kaluza-Klein black holes
Both black hole kaluza-klein thermodynamics first law static black holes
2014/12/20
We consider how variations in the moduli of the compactification manifold contribute `pdV' type work terms to the first law for Kaluza-Klein black holes. We give a new proof for the S1 case, based on ...

Both black hole kaluza-klein thermodynamics time and space
2014/12/20
We study the thermodynamics of Kaluza-Klein black holes with momentum along the compact dimension, but vanishing angular momentum. These black holes are stationary, but non-rotating. We derive the fir...

A Killing bubble is a minimal surface that arises as the fixed surface of a spacelike Killing field. We compute the bubble contributions to the Smarr relations and the mass and tension first laws for ...

In this report, we consider the six-dimensional Kaluza-Klein models with spherical compactification of the internal space. Here, we investigate the case of bare gravitating compact objects with the du...

We study the collapse of the universe described by a scalar field spherically symmetric collapse of a system described by a massless scalar field from a 5D Riemann-flat canonical metric, on which we m...
Weak-field limit of Kaluza-Klein models with spherical compactification II: agreement with the observations
Weak-field limit Kaluza-Klein models spherical compactification agreement observations
2011/10/17
We investigate the classical gravitational tests for the Kaluza-Klein model with spherical (of a radius $a$) compactification of the internal space. The model contains also a bare cosmological constan...

2011/10/17
We investigate classical gravitational tests for the Kaluza-Klein model with spherical compactification of the internal two-dimensional space. In the case of the absence of a multidimensional bare cos...
Perturbation of heliosynchronous orbits in stable Kaluza-Klein theory

Although the methods and techniques have been greatly improved since the late nineteenth century, the precision on the measurement of the gravitational constant G does not exceed 1 part in 1000. Intri...
一个八维Kaluza-Klein宇宙模型
宇宙标度因子 八维Kaluza-Klein宇宙模型
2009/7/27
本文讨论了一个八维Kaluza-Klein宇宙模型.它不仅自洽地包含Georgi三族SU(11)大统一模型,而且得到了与观测宇宙一致的物理解.在这一模型中,通常四维的宇宙标度因子记作R3而额外维度的宇宙标度因子记作R4,它们的物理性质可分成四个阶段来描述.第一阶段,R3和R4都在膨胀;第二阶段,R3是一个inflation解而R4是个常数;第三阶段,R4开始坍缩到它的极小值,而R3继续单调地增加;...
由于偶数维与奇数维时空中的旋量差别很大,在偶数维与奇数维纯Kaluza-Klein理论的孤子背景中的费米子动力学性质有本质差异.本文讨论了费米子在6维纯Kaluza-Klein理论的孤子背景中运动方程导出的一般方法,并以球对称孤子示例.中性无质量费米子方程能完全退耦,并与在Schwarzschild黑洞情形时零四元组形式所得到的方程一致.
