As a prospective resolution of the Hubble tension, early dark energy (EDE) suffers from the coincidence problem, why EDE is active just at matter-radiation equality (equivalently why the slope of EDE potential is required to approximately equal to the Hubble parameter at that time). In this paper we present a dark-matter-trapped EDE mechanism, by which the bound on the slope of EDE potential can be relieved. We show how this mechanism can work, and discuss the possibility that after inflation ended EDE can settle down at the initial conditions required by observations.

被困的早期暗能量


作为哈勃张力的前瞻性解决方案，早期暗能量（EDE）遇到了重合问题，为什么EDE仅在物质辐射相等时才活跃（相当于为什么EDE势的斜率需要近似等于该处的哈勃参数）时间）。在本文中，我们提出了一种暗物质捕获 EDE 机制，通过该机制可以缓解 EDE 电势斜率的限制。我们展示了这种机制如何运作，并讨论了膨胀结束后 EDE 可以稳定在观测所需的初始条件的可能性。
