Brans-Dicke真空的一个新的可穿越虫洞解

A new traversable wormhole solution in vacuum Brans Dicke theory

在ＢｒａｎｓＤｉｃｋｅ理论框架内给出一个新的球对称真空静态精确解，并显示该解有虫洞几何（ｗｏｒｍｈｏｌｅｇｅｏｍｅｔｒｙ）若适当选取无量纲耦合常数ω（－２≤ω≤０）和积分常数值，则该解是双向可穿越虫洞（ｔｗｏｗａｙｔｒａｖｅｒｓａｂｌｅｗｏｒｍｈｏｌｅ）解标量场起异常物质（ｅｘｏｔｉｃｍａｔｅｒ）的作用。

A new set of symmetric and static exact solutions in vacuum Brans Dicke theory is obtained and it admits wormhole geometry. Two way traversable wormholes in the Brans Dicke theory are allowed for the coupling parameter ω(-2≤ω≤0) and appropriately chosen integration constants.The scalar field  plays the role of exotic matter which violats the weak energy condition.
