费米气体中纠缠态的状态方程

Equation of state for Entanglement in a Fermi gas

Christian Lunkes, Caslav Brukner, Vlatko Vedral

摘要:

纠缠距离是简并电子气中两个纠缠电子之间的最大距离。超过这个距离,所有的纠缠都消失了。我们将极端相对论和非相对论系统的纠缠距离与简并压力联系起来,估计了白矮星中的纠缠距离。把纠缠作为一个物理量,把纠缠的形成熵和纠缠度与相对电子距离、压强和温度联系起来,建立了一个新的纠缠态方程。

英文摘要:

Entanglement distance is the maximal separation between two entangled electrons in a degenerate electron gas. Beyond that distance, all entanglement disappears. We relate entanglement distance to degeneracy pressure both for extreme relativistic and non-relativistic systems, and estimate the entanglement distance in a white dwarf. Treating entanglement as a thermodynamical quantity, we relate the entropy of formation and concurrence to relative electron distance, pressure, and temperature, to form a new equation of state for entanglement.
