论文摘要
在连续体（BIC）中的结合状态中，复合粒子的质量大于其成分的总质量。使用梯子Bethe-Salpeter方程，研究了两个带电粒子$ a $ a $和$ b $的系统中的BIC状态，其中包括不同的质量（$ M_ {B} >> M_ {A} $）。我们证明，对于阳性结合能，有两个动量空间区域，其中颗粒之间的电磁相互作用得到了强烈增强，而有效耦合恒定则相当于$α\ sqrt {m_ {b}/m_ {b}/m_ {a}} $，其中$ a $ a $是$α$的良好结构常数。相互作用的谐振导致在BIC状态下的成分与阳性结合能，该结合能是较轻的粒子质量的顺序。
In bound states in the continuum (BIC) the mass of a composite particle is greater than the total mass of its constituents. Using the ladder Bethe-Salpeter equation, the BIC state in a system of two charged particles $a$ and $b$ with different masses ($m_{b}>>m_{a}$) is investigated. We demonstrate that for the positive binding energy, there are two momentum space regions in which the electromagnetic interaction between the particles is strongly enhanced, and the effective coupling constant turns out to be equal to $α\sqrt{m_{b}/m_{a}}$, where $α$ is the fine structure constant. The interaction resonance leads to confinement of the constituents in the BIC state with the positive binding energy which is of the order of the mass of the lighter particle from the pair.
