可积XY中心自旋模型中的暗态

Dark states in an integrable XY central spin model

Jaco van Tonder, Jon Links

AI总结:

该研究在可积XY中心自旋模型中发现了暗态,并证明其仅存在于特定中心自旋磁场构型下,通过显式构造Bethe态加以验证。

摘要:

中心自旋模型中,中心自旋与环境不纠缠的本征态被称为暗态。最近在一类可积XX模型中观察到了暗态。这里我们发现暗态存在于XY模型中,但仅当中心自旋磁场处于特定构型时。我们通过显式构造Bethe态来证明这一点。

英文摘要:

Eigenstates of central spin models in which the central spin is unentangled with the environment are known as dark states. They have recently been observed in a class of integrable XX models. Here we find that dark states are present in XY models, but only for particular configurations of the central spin magnetic field. We show this via an explicit construction of the Bethe states.
