The interaction between dark matter and dark energy (DE) can be incorporated into field theory models of DE that have proved successful in alleviating the coincidence problem. We review recent advances in this field, including new models and constraints from different astronomical data sets. We show that interactions are allowed by observations and can reduce the current tensions among different measurements of cosmological parameters. We extend our discussion to include constraints from non-linear effects and results from cosmological simulations. Finally, we discuss forthcoming multi-messenger data from current and future observational facilities that will help to improve our understanding of the interactions within the dark sector.

进一步认识暗能量与暗物质的相互作用：现状与未来方向

暗物质和暗能量（DE）之间的相互作用可以纳入DE的场论模型中，该模型已被证明可以成功地缓解重合问题。我们回顾了该领域的最新进展，包括来自不同天文数据集的新模型和约束。我们表明，观测允许相互作用，并且可以减少当前宇宙学参数不同测量之间的紧张关系。我们将讨论扩展到包括非线性效应的约束和宇宙学模拟的结果。最后，我们讨论了来自当前和未来观测设施的即将到来的多信使数据，这将有助于提高我们对暗区内部相互作用的理解。
