论文摘要
为了继承全循环量子brans-dicke理论的更多特征，在循环量子量子brans brans-dicke宇宙学中独立量化了汉密尔顿约束的欧几里得和洛伦兹术语。在宇宙学模型中获得了替代性哈密顿约束操作员及其有效表达。在有效的哈密顿约束中发现了残留的量子校正项，该约束中没有类似于一般相对论的环路量子宇宙学的有效哈密顿量。详细分析了这种有效的哈密顿约束驱动的动态。对于$ω\ gg 1 $的物理有趣情况，这种有效的哈密顿式驱动了弹跳的演变，该进化从de Sitter Universe演变为经典的Brans-Dicke解决方案。
To inherit more features of full loop quantum Brans-Dicke theory, the Euclidean and Lorentzian terms of the Hamiltonian constraint are quantized independently in loop quantum Brans-Dicke cosmology. An alternative Hamiltonian constraint operator and its effective expression are obtained in the cosmological model. A residual quantum correction term is found in the effective Hamiltonian constraint, which has no analog in the effective Hamiltonian of the loop quantum cosmology from general relativity. The dynamics driven by this effective Hamiltonian constraint is analyzed in detail. For the physically interesting case of $ω\gg 1$, this effective Hamiltonian drives a bouncing evolution which evolves from a de Sitter universe to a classical Brans-Dicke solution.
