论文摘要
我们提出了一个基于储层工程的抗铁磁自旋系统的光子量子模拟器。我们考虑了一个方案，该方案是通过损耗的辅助腔间间接耦合的四四极驱动的耗散kerr腔。我们表明，辅助腔可以产生有效的耗散性和汉密尔顿抗铁磁性耦合。通过求解三角形腔构型的主方程，我们证明了系统的非平衡稳态具有完全类比，其基态与抗Fiferromagnetic Ising模型的基态，表现出挫败感的关键特征。我们表明，当有效的光子跳跃幅度为零时，仅工程的非本地耗散就可以诱导抗铁磁相互作用和挫败感。这个简单的方案可以推广到任意晶格几何形状，为在受控的量子光学平台上模拟反铁磁性和挫败感提供了完全可控的配方。
We propose a photonic quantum simulator for anti-ferromagnetic spin systems based on reservoir engineering. We consider a scheme where quadratically driven dissipative Kerr cavities are indirectly coupled via lossy ancillary cavities. We show that the ancillary cavities can produce an effective dissipative and Hamiltonian anti-ferromagnetic-like coupling between the cavities. By solving the master equation for a triangular cavity configuration, we demonstrate that the non-equilibrium steady state of the system bears full analogy with the ground state of an antiferromagnetic Ising model, exhibiting key signatures of frustration. We show that when the effective photon hopping amplitude is zero, the engineered non-local dissipation alone is capable of inducing antiferromagnetic interaction and frustration. This simple scheme can be generalised to arbitrary lattice geometries, providing a fully controllable recipe for simulating antiferromagnetism and frustration on a controlled quantum optical platform.
