量子信息暗能量:来自遗忘的暗能量
Quantum Informational Dark Energy: Dark energy from forgetting
摘要:
我们认为,暗能量有一个量子信息的起源。与宇宙视界量子信息擦除相关的朗道原理意味着具有有效负压的非零真空能量。在假设事件视界的全息原理、最小自由能条件和Gibbons-Hawking温度的条件下,我们得到了参数为$d\simeq 1$的全息暗能量,这与目前的观测数据是一致的。结果还表明,纠缠能和视界能都与Landauer原理有关。
英文摘要:
We suggest that dark energy has a quantum informational origin. Landauer's principle associated with the erasure of quantum information at a cosmic horizon implies the non-zero vacuum energy having effective negative pressure. Assuming the holographic principle, the minimum free energy condition, and the Gibbons-Hawking temperature for the cosmic event horizon we obtain the holographic dark energy with the parameter $d\simeq 1$, which is consistent with the current observational data. It is also shown that both the entanglement energy and the horizon energy can be related to Landauer's principle.
