耦合复吸收势的慢变量离散方法计算三体共振
Calculation of three-body resonances using slow-variable discretization coupled with complex absorbing potential
摘要：
我们开发了一种方法来计算三体共振的位置和宽度。该方法结合了超球绝热方法、慢变量离散化方法（Tolstikhin等人，J. Phys. B：At.摩尔Opt.Phys.29，L389（1996））和复合吸收势。该方法可用于获得具有短程或长程波函数的谐振。特别地，我们应用该方法来获得模型系统的非常浅的三体Efimov共振（Nielsen等人，A 66，012705（2002））。
英文摘要：
We developed a method to calculate positions and widths of three-body resonances. The method combines the hyperspherical adiabatic approach, slow variable discretization method (Tolstikhin et al., J. Phys. B: At. Mol. Opt. Phys. 29, L389 (1996)), and a complex absorbing potential. The method can be used to obtain resonances having short-range or long-range wave functions. In particular, we applied the method to obtain very shallow three-body Efimov resonances for a model system (Nielsen et al., Phys. Rev. A 66, 012705 (2002)).
