拟精确可解差分方程

Quasi Exactly Solvable Difference Equations

Ryu Sasaki

摘要:

几个明确的例子,准精确可解的“离散”量子力学哈密顿量的变形著名的精确可解的一个自由度的哈密顿量。这些是著名的准精确可解系统的差分模拟,即由六次势变形的谐振子(有/没有离心势)和由cos 2x势变形的1/sin^2x势。它们有有限个可精确计算的本征值和本征函数。

英文摘要:

Several explicit examples of quasi exactly solvable `discrete' quantum mechanical Hamiltonians are derived by deforming the well-known exactly solvable Hamiltonians of one degree of freedom. These are difference analogues of the well-known quasi exactly solvable systems, the harmonic oscillator (with/without the centrifugal potential) deformed by a sextic potential and the 1/sin^2x potential deformed by a cos2x potential. They have a finite number of exactly calculable eigenvalues and eigenfunctions.
