标题： Confinement-Induced Resonances in Spherical Shell Traps

摘要： 两粒子在球对称壳势阱中，通过三维零程势相互作用的能谱及相应的波函数被计算出来。 完全源于两粒子相对运动和质心运动之间强耦合的束缚诱导共振，在某些壳半径值下被识别为避碰交叉。 通过接近这些共振，这些结果提供了一种新的方法，仅调节壳的几何参数即可控制原子气体中的原子间相互作用。 显示英文摘要

摘要： The energy spectrum and corresponding wave functions of two bosonic particles confined in a spherically symmetric shell trap and interacting via a three-dimensional zero-range potential are computed. Confinement-induced resonances, originating entirely from the strong coupling of the relative and center-of-mass motions of the two particles, are identified as avoided crossings for certain values of the shell radius. By working close to the found resonances, these results offer a new way to control the atom-atom interaction in an atomic gas by tuning only the geometrical parameters of the shell.
