宏观纠缠普适性的一个简单实验证明
A simple thermodynamical witness showing universality of macroscopic entanglement
摘要：
我们证明，如果给定系统的基态纠缠超过其总熵，则该系统处于纠缠态。这是一个普遍的纠缠见证，适用于任何物理系统，并产生一个温度，低于这个温度，我们肯定会发现一些纠缠。我们的证人，然后适用于一般玻色子和费米多体系统，以获得相应的“临界”温度，具有非常广泛的有效性。
英文摘要：
We show that if the ground state entanglement exceeds the total entropy of a given system, then this system is in an entangled state. This is a universal entanglement witness that applies to any physical system and yields a temperature below which we are certain to find some entanglement. Our witness is then applied to generic bosonic and fermionic many body systems to derive the corresponding "critical" temperatures that have a very broad validity.
