By using group representation theory, th quasi-adiabatic approximation solution of the schrodinger equation of a quantum system with slowly-changing Hamiltonian are presented in this paper. We not only obtained the Berry phase factor and strictly proved the quantum adiabatic theorem as the zeroth-order approximation, but also studied the universal Berry phase factor and its geometrical interpretation when the adiabatic condition is violated. It is pointed out that this universal Berry phase factor has observable...

By using group representation theory, th quasi-adiabatic approximation solution of the schrodinger equation of a quantum system with slowly-changing Hamiltonian are presented in this paper. We not only obtained the Berry phase factor and strictly proved the quantum adiabatic theorem as the zeroth-order approximation, but also studied the universal Berry phase factor and its geometrical interpretation when the adiabatic condition is violated. It is pointed out that this universal Berry phase factor has observable effects.

本文首先基于群论的方法,通过分析量子体系哈密顿的对称性,给出一种求解波动方程的近似方法——准绝热近似,以用来解决体系的哈密顿量作缓慢有限改变的量子跃迁问题.作为零级近似,严格地证明了具有简并情况的量子绝热定理,它的推论给出具有明显拓朴性质的Berry相因子.我们还给出了绝热条件破坏的几何解释,并说明了Berry相因子普遍存在于以哈密顿量确定的变化所需时间T所标度的量子过程中.最后我们指出了对应于绝热条件破坏的缓变过程的可观察效应.

This paper gives an economics model which relates intertemporal general equilibrium theory with neo Ricardian production price theory and develops the model of Rose Anne Dana, which modifies finite consumers to consumers continuum.

This paper gives an economics model which relates intertemporal general equilibrium theory with neo Ricardian production price theory and develops the model of Rose Anne Dana, which modifies finite consumers to consumers continuum. It adds two assumptions on the basis of the model of Rose Anne Dana, obtaining two main results:(1) under standard assumptions, this intertemporal model has an equilibrium such that in each period the rate of maximum profit is uniform among producers,(2)if it considers prices of production are stationary,which is equal to the rate of maximun profits,under mild conditions such a price system exists and is unique, and the sequence of undercounted prices of the equilibrium defined above converge to production price. Therefore, the equilibrium price relies on technology feature, but the price involved relies on technology when resolving limit.

本文给出了一个经济模型把跨期间的一般均衡理论和neo Ricardian的生产价格理论联系起来 ,并改进了Rose AnneDana模型[1] [2 ] ,即把消费者有限改变消费者连续统 ,并在Rose AnneDana模型的基础上 ,加了条件C .4和C .7,得出了两个重要的结果 :(1)在标准条件下 ,此模型有一均衡使得每一个生产者的每期最大利润是相等的 ;(2 )如考虑生产价格是稳定价格 ,且等于最大利润 ,则在适当的条件下 ,这样的价格系统是存在且是唯一的 ,而所定义的均衡的非折扣的价格序列收敛于生产价格。因此均衡价格依赖于技术和消费者特征 ,但在取极限时 ,有关价格仅依赖于技术。
