重新审视马尔可夫近似：标准量子布朗运动模型的不一致性

The Markov approximation revisited: Inconsistency of the standard quantum Brownian motion model

我们重新审视马尔可夫近似必要的普通布朗运动从一个模型广泛采用的文献中为这个特定的目的。我们表明，这导致内部的不一致，从而意味着需要进一步寻找一个更令人满意的模型。

多周期相干态与WKB精确性II "非紧情形与经典理论“

Multi-Periodic Coherent States and the WKB-Exactness II ``Non-compact Case and Classical theories Revisited''

我们证明了WKB近似给出了$CP^N$的非紧对应物“$CQ^N$”的迹公式在"多重相干态“下的精确结果。我们重新讨论了$CP^N$和$CQ^N$上的辛2-形式，特别是构造了具有酉形式的$CQ^N$上的辛2-形式.我们还重新讨论了它们的经典配分函数的精确计算。

偶极近似下的自发辐射——再考察

Spontaneous emission in dipole approximation -- revisited

本文结合源场理论与薛定谔绘景重新分析偶极近似自发辐射，检验不作 RWA/WWA 时的能量场量，并指出全频率微扰求和导致非物理布居。

Morse potential in relativistic contexts from generalized momentum operator, Pekeris approximation revisited and mapping

In this work we explore a generalization of the Dirac and Klein-Gordon (KG) oscillators, provided with a deformed linear momentum inspired in nonextensive statistics, that gives place to the Morse potential in relativistic contexts by first principles. In the (1+1)-dimensional case the relativistic oscillators are mapped into the quantum Morse potential. Using the Pekeris approximation, in the (3+1)-dimensional case we study the thermodynamics of the S-waves states (l=0) of the H2, LiH, HCl and CO molecules (in the non-relativistic limit) and of a relativistic electron, where Schottky anomalie…

“狭缝量子干涉”再探

"Quantum Interference with Slits" Revisited

Marcella [arXiv：quant-ph/0703126]提出了一种采用狄拉克形式计算单缝和双缝干涉图样的简单方法。他声称没有参考经典光学或散射理论，因此他的方法提供了这些实验的纯量子力学描述。他还提出了他的计算，如果没有近似雇用。我们表明，他含蓄地使相同的近似发现在经典治疗的干扰，并没有新的物理已被引入。与此同时，Marcella给出的一些量子力学论点充其量是误导。

Ehrenfest's Theorem Revisited

Historically, Ehrenfest's theorem (1927) is the first one which shows that classical physics can emerge from quantum physics as a kind of approximation. We recall the theorem in its original form. Next, we highlight its generalizations to the relativistic Dirac particle, and to a particle with spin and izospin. We argue that apparent classicality of the macroscopic world can probably be explained within the framework of standard quantum mechanics.
