论文摘要
在这项工作中，我们提出了一个新型的固态平台，用于创建基于半导体中植入的自旋中心的量子模拟器。我们表明，在存在外部磁场的存在下，可以将通过磁性偶极 - 偶极相互作用相互作用的$ S = 1 $旋转中心映射到与外部磁场中XYZ模型相等的有效旋转半升压系统。有趣的是，该系统提出了广泛的量子相和临界行为，可以通过磁场和自旋中心的定向排列来控制。我们证明我们的相互作用的自旋链可以调整为各向同性的海森堡模型和横向场伊斯丁普遍性类别。值得注意的是，我们的模型包含一条线，其中系统处于临界浮动阶段，该线路终止于Berezinskii-Kosterlitz- thouless-Thouless和Pokrovsky-Talapov过渡点。我们将该系统作为基于自旋中心的浮动阶段的第一个固态量子模拟器。
In this work we propose a novel solid-state platform for creating quantum simulators based on implanted spin centers in semiconductors. We show that under the presence of an external magnetic field, an array of $S=1$ spin centers interacting through magnetic dipole-dipole interaction can be mapped into an effective spin-half system equivalent to the XYZ model in an external magnetic field. Interestingly, this system presents a wide range of quantum phases and critical behaviors that can be controlled via magnetic field and orientational arrangement of the spin centers. We demonstrate our interacting spin chain can be tuned to both isotropic Heisenberg model and transverse-field Ising universality class. Notably, our model contains a line where the system is in a critical floating phase that terminates at Berezinskii-Kosterlitz-Thouless and Pokrovsky-Talapov transition points. We propose this system as the first solid-state quantum simulator for the floating phase based on spin centers.
