摘要:

本文分析了超对称FRW模型中均匀标量场超多重态与标度因子相互作用的超对称宇宙学模型。在标度因子和标量场中出现了费米子超伴子,并由超Wheeler-DeWitt方程通过通常的WKB方法得到了经典的运动方程.由此得到的超对称Einstein-Klein-Gordon方程包含额外辐射项和刚性物质项,我们研究了它们在平坦空间中不同标量场势下的解.的解决方案相比,标准的情况下,特别是那些对应的指数潜力,其影响的早期宇宙的动力学依次讨论。

英文摘要:

In this work a supersymmetric cosmological model is analyzed in which we consider a general superfield action of a homogeneous scalar field supermultiplet interacting with the scale factor in a supersymmetric FRW model. There appear fermionic superpartners associated with both the scale factor and the scalar field, and classical equations of motion are obtained from the super-Wheeler-DeWitt equation through the usual WKB method. The resulting supersymmetric Einstein-Klein-Gordon equations contain extra radiation and stiff matter terms, and we study their solutions in flat space for different scalar field potentials. The solutions are compared to the standard case, in particular those corresponding to the exponential potential, and their implications for the dynamics of the early Universe are discussed in turn.
