We propose a scheme for preparing and stabilizing the Pfaffian state with high fidelity in rapidly rotating 2D traps containing a small number of bosons. The goal is achieved by strongly increasing three-body loss processes, which suppress superpositions of three particles while permitting pairing. This filtering mechanism gives rise to reasonably small losses if the system is initialized with the right angular momentum. We discuss some methods for tuning independently two- and three-body interactions.
我们提出了一种在含有少量玻色子的快速旋转二维陷阱中以高保真度制备和稳定 Pfaffian 态的方案。通过强烈增加三体损耗过程来实现这一目标,这一过程抑制了三个粒子的叠加,同时允许配对。如果系统以正确的角动量初始化,这种滤波机制会导致相当小的损耗。我们讨论了一些独立调节二体和三体相互作用的方法。
