p-力学的量子经典括号

A Quantum-Classical Brackets from p-Mechanics

Vladimir V. Kisil

摘要:

我们提供了一个答案,在一个单一的形式主义混合量子和经典动力学的长期存在的问题。该结构是基于从海森堡群的表示理论中对量子和经典动力学的p-力学推导(quant-ph/0212101,quant-ph/0304023)。为了实现量子-经典混合,我们取代表两个不同普朗克常数的海森堡群的两个副本的乘积。与以前的猜测相比,我们的答案包含一个额外的分析性质的术语,这是以前在纯代数设置中没有得到的。保留字:Moyal括号,Poisson括号,交换子,Heisenberg群,轨道方法,表示论,普朗克常数,量子-经典混合

英文摘要:

We provide an answer to the long standing problem of mixing quantum and classical dynamics within a single formalism. The construction is based on p-mechanical derivation (quant-ph/0212101, quant-ph/0304023) of quantum and classical dynamics from the representation theory of the Heisenberg group. To achieve a quantum-classical mixing we take the product of two copies of the Heisenberg group which represent two different Planck's constants. In comparison with earlier guesses our answer contains an extra term of analytical nature, which was not obtained before in purely algebraic setup. Keywords: Moyal brackets, Poisson brackets, commutator, Heisenberg group, orbit method, representation theory, Planck's constant, quantum-classical mixing
