Maxwell理论中局域激发态的量子纠缠

Quantum Entanglement of Locally Excited States in Maxwell Theory

Masahiro Nozaki, Naoki Watamura

摘要:

在四维Maxwell规范理论中,我们研究了(Renyi)纠缠熵的变化,纠缠熵定义为用规范不变的局域算符作用于基态产生的局域激发态的熵减去基态的熵.本文所考虑的算子的变化反映了电磁对偶性。变化的后期值可以用电磁准粒子来解释。当由电场和磁场构成的算符作用于基态时,表明算符对量子纠缠的后期结构的作用不同于自由标量场。

英文摘要:

In 4 dimensional Maxwell gauge theory, we study the changes of (Renyi) entangle-ment entropy which are defined by subtracting the entropy for the ground state from the one for the locally excited states generated by acting with the gauge invariant local operators on the state. The changes for the operators which we consider in this paper reflect the electric-magnetic duality. The late-time value of changes can be interpreted in terms of electromagnetic quasi-particles. When the operator constructed of both electric and magnetic fields acts on the ground state, it shows that the operator acts on the late-time structure of quantum entanglement differently from free scalar fields.
