朗道原理与广义相对论

Landauer Principle and General Relativity

L. Herrera

摘要:

我们试图说明的物理相关性的兰道尔原则适用于不同的重要问题的引力理论。我们将首先在广义相对论的背景下分析由朗道原理所暗示的信息具有质量这一事实所得出的结论。接下来,我们将分析兰道尔原理所起的作用,以便理解为什么不同的观测者全等性对同一时空提供了非常不同的物理描述。最后,我们将把朗道原理应用于引力辐射问题。我们将看到,引力辐射是一个必然耗散的不可逆过程,这一事实是朗道原理和引力辐射传递信息这一事实的直接结果。应获得一个测量与辐射信息相对应的辐射能量部分的表达式和一个定义在该过程中擦除的比特总数的表达式,以及一个将后者与邦迪新闻功能联系起来的显式表达式。

英文摘要:

We endeavour to illustrate the physical relevance of the Landauer principle applying it to different important issues concerning the theory of gravitation. We shall first analyze, in the context of general relativity, the consequences derived from the fact, implied by Landauer principle, that information has mass. Next, we shall analyze the role played by the Landauer principle in order to understand why different congruences of observers provide very different physical descriptions of the same space--time. Finally, we shall apply the Landauer principle to the problem of gravitational radiation. We shall see that the fact that gravitational radiation is an irreversible process entailing dissipation, is a straightforward consequence of the Landauer principle and of the fact that gravitational radiation conveys information. An expression measuring the part of radiated energy that corresponds to the radiated information and an expression defining the total number of bits erased in that process, shall be obtained, as well as an explicit expression linking the latter to the Bondi news function.
