单声子作用下的Landau—Zener隧穿概率研究

摘要

A new complete basis set was adopted to solve single-phonon Landau-Zener tunneling probability by solving the Schrodinger differential equation, then the result was compared with the result got by solving Landau-Zener formula. The result show that: In the case of weak coupling,the tunneling probability by solving the Schrodinger differential equation is consistent with the result got by solving Landau-Zener formula.%采用一种新的完备基矢,通过解薛定谔微分方程对Landau-Zener模型单模情况下的隧穿概率进行求解,再跟Landau-Zener概率公式计算出来的隧穿概率进行比较,计算的结果表明:在耦合强度比较低的情况下,通过解薛定谔微分方程求解出来的隧穿概率比较符合Landau-Zener概率公式计算出来的隧穿概率.
