AI 中文摘要
我们研究一维标量模型,描述有效质量准粒子场与至多含一个激发的两能级原子连续体耦合的情况。针对原子密度为常数、空间局域且符号确定的扰动,证明束缚态存在的一般性定理,并分析多个可精确求解例子中的束缚态。
英文摘要
We study a one-dimensional scalar model for an effective-mass quasiparticle field coupled to a continuum of two-level atoms with at most one excitation present. We prove a general theorem on the existence of bound states under sign-definite spatially localized perturbations of constant atomic density and analyze the bound states for several exactly solvable examples.
