强三体耗散产生Pfronan态

Pfaffian State Generation by Strong 3-Body Dissipation

M. Roncaglia, M. Rizzi, J. I. Cirac

摘要:

我们提出了一个方案,用于制备和稳定的Pfronan态具有高保真度的快速旋转的二维陷阱包含少量的玻色子。这一目标是通过强烈增加三体损失过程来实现的,三体损失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,这种过滤机制会产生相当小的损失。我们讨论了一些方法来调整3体相互作用独立的2体碰撞。

英文摘要:

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 3-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 3-body interactions independently of 2-body collisions.
