BPS方程和应力张量

BPS Equations and the Stress Tensor

E. F. Moreno, F. A. Schaposnik

摘要:

我们利用能量动量张量的空间分量与超流之间的关系,讨论了BPS方程与各种超对称孤子理论中应力张量分量消失之间的联系。利用某些超荷组合湮灭BPS态的事实,我们证明了扭结、涡旋和双子的$T_{ij}=0$,显示了超对称性和非相互作用BPS孤子之间的联系。

英文摘要:

We exploit the relationship between the space components of the energy-momentum tensor and the supercurrent to discuss the connection between the BPS equations and the vanishing of the components of the stress tensor in various supersymmetric theories with solitons. Using the fact that certain combination of supercharges annihilate BPS states, we show that $T_{ij}=0$ for kinks, vortices and dyons, displaying the connection between supersymmetry and non-interacting BPS solitons.
