论文摘要
由于Kalb-Ramond场的真空期望值（VEV），我们获得了静态的球形对称虫洞溶液。 Kalb-Ramond VEV是一个背景张量场，它会产生时空的局部Lorentz对称性破裂（LSB）。考虑到Kalb-Ramond（VEV）和Ricci张量之间的非最小耦合，我们发现由具有负各向同性压力的物质来源维持的确切的可穿越的虫孔溶液。对于LSB参数的特殊选择，该物质源满足喉咙处的能量条件。此外，我们采用高斯河网方法来分析弱极限近似中光的挠度。
We obtain a static spherically symmetric wormhole solution due to the vacuum expectation value (VEV) of a Kalb-Ramond field. The Kalb-Ramond VEV is a background tensor field which produces a local Lorentz symmetry breaking (LSB) of spacetime. Considering a non-minimal coupling between the Kalb-Ramond (VEV) and the Ricci tensor, we found an exact traversable wormhole solution sustained by matter sources with a negative isotropic pressure. The matter source satisfies the energy conditions at the throat for particular choices of the LSB parameter. Moreover, we employ the Gauss-Bonnet method to analyze the deflection angle of light in the weak limit approximation.
