摘要:
从几个束缚态能级重构径向(一维)量子势V(r)是一个长期存在的反问题,因为有限的谱数据必须约束整个势。我们提出了一种拉普拉斯-动量重构流程,将伯特兰-马丁间隙界与广义伯特兰-马丁(GBM)偶动量阶梯连接,继续用帕德近似扩展拉普拉斯变换,并反向变换以恢复ρ(r)和V(r)。奇动量通过物理一致的插值方案提供。对库仑、谐振子、胡尔滕、克拉特泽和双曲井情况的基准设置和诊断被陈述,以便每个近似阶段可以在共同的经验基础上评估。结论因此仅限于报告的基准设置,而不是作为普遍方法声明。
英文摘要:
Reconstructing a radial (1D) quantum potential, V(r), from a few bound-state energies is a long-standing inverse problem because limited spectral data must constrain an entire potential. We present a Laplace-moment reconstruction pipeline that links the Bertlmann-Martin gap bound to generalized Bertlmann-Martin (GBM) even-moment ladders, continues the Laplace transform with Pade approximants, and inverts the transform to recover rho(r) and V(r). Odd moments are supplied by a physically consistent interpolation scheme. Benchmark settings and diagnostics for Coulomb, harmonic oscillator, Hulthen, Kratzer, and hyperbolic-well cases are stated so each approximation stage can be assessed under a common empirical basis. The conclusions are therefore limited to the reported benchmark settings rather than offered as universal method claims.
