全息热机效率的精确公式

An Exact Efficiency Formula for Holographic Heat Engines

Clifford V. Johnson

摘要:

进一步考虑黑洞热机的效率,通过pdV条款中存在的扩展引力热力学第一定律进行机械工作。注意,当发动机循环是具有平行于(p,V)轴的边的矩形时,效率可以简单地根据在拐角处评估的黑洞的质量来写。由于一个任意的周期可以近似到任何所需的精度由矩形的平铺,计算效率的一般几何算法如下。一个简单的概括的算法,使其适用于更一般的类热机,超越了黑洞的背景。

英文摘要:

Further consideration is given to the efficiency of black hole heat engines that perform mechanical work via the pdV terms present in the First Law of extended gravitational thermodynamics. It is noted that when the engine cycle is a rectangle with sides parallel to the (p,V) axes, the efficiency can be written simply in terms of the mass of the black hole evaluated at the corners. Since an arbitrary cycle can be approximated to any desired accuracy by a tiling of rectangles, a general geometrical algorithm for computing the efficiency follows. A simple generalization of the algorithm renders it applicable to more general classes of heat engine, beyond the black hole context.
