具有有效量子势的低动量经典力学

Low Momentum Classical Mechanics with Effective Quantum Potentials

Fernando Haas

摘要:

在相空间的低动量区域研究了新近引入的有效量子势理论。利用这种低动量近似,我们证明了新的有效量子势诱导了一个依赖于空间的质量和一个光滑势,它们都是由经典势构造的。给出了近似理论在一维空间中的精确解,提出了有效量子势的有效透射系数和反射系数的概念,并与类似的量子统计混合问题进行了比较。结果被应用到一个正方形的障碍的情况下。

英文摘要:

A recently introduced effective quantum potential theory is studied in a low momentum region of phase space. This low momentum approximation is used to show that the new effective quantum potential induces a space-dependent mass and a smoothed potential both of them constructed from the classical potential. The exact solution of the approximated theory in one spatial dimension is found. The concept of effective transmission and reflection coefficients for effective quantum potentials is proposed and discussed in comparison with an analogous quantum statistical mixture problem. The results are applied to the case of a square barrier.
