磁原子电子顺磁共振的广义开放量子系统方法

A Generalized Open Quantum System Approach for the Electron Paramagnetic Resonance of Magnetic Atoms

Gal Shavit, Baruch Horovitz, Moshe Goldstein

摘要:

最近的一项实验突破允许在STM装置中探测单个磁性原子的电子参数共振。结果提出了有趣的功能,如一个不对称的线型和异常大的比例的消相干和衰减率,这违背了标准的方法,使用传统的布洛赫方程。为了解决这些问题,我们采用新的广义布洛赫方程,连同适当的微观模型的磁性吸附原子,并显示如何所有的实验功能可以自然地占。所提出的方法也可以用于处理任何未来的类似实验,以及下一代混合量子器件。

英文摘要:

A recent experimental breakthrough allowed to probe electronic parametric resonance of a single magnetic atom in an STM setup. The results present intriguing features, such as an asymmetric lineshape and unusually large ratio of the decoherence and decay rates, which defy standard approaches using the conventional Bloch equations. To address these issues we employ novel generalized Bloch equations, together with proper microscopic modeling of the magnetic adatom, and show how all the experimental features can naturally be accounted for. The proposed approach may also be useful in treating any future similar experiments, as well as next generation hybrid quantum devices.
