The continuous confinement of quantum systems can be described by means of the d-method, where the dimension d is taken as a continuous parameter. In this work we describe in detail how this method can be used to obtain the root mean square radii for a squeezed three-body system. These observables are used to investigate the disappearance of the Efimov states around the two-body threshold during a progressive confinement of the system from three to two dimensions. We illustrate how the disappearance takes place through the loss of one of the particles, whereas the other two remain bound.

封闭后的Efimov效应蒸发

可以通过d方法描述量子系统的连续约束，其中d为连续参数。在这项工作中，我们详细描述了该方法如何用于获得压缩三体系统的均方根半径。这些可观的观测值用于研究在系统从三个维度逐步限制为两个维度的过程中，两体阈值附近的Efimov状态的消失。我们说明了消失是如何通过丢失其中一个粒子而发生的，而其他两个粒子仍然是束缚的。
