关于Cayley树上的量子Markov链Ⅰ:二阶Cayley树上XY-模型相伴链的唯一性

On Quantum Markov Chains on Cayley tree I: uniqueness of the associated chain with XY-model on the Cayley tree of order two

Luigi Accardi, Farrukh Mukhamedov, Mansoor Saburov

摘要:

本文研究Cayley树上的前向量子马尔可夫链。给出了这种QMC的一种构造方法,即在有限体积上构造具有边界条件的态,并将QMC定义为这些态的依赖于边界条件的弱极限。使用所提供的结构,我们调查QMC与XY-模型上的二阶凯莱树。我们证明了与这类模型相关的QMC的唯一性,这意味着QMC不依赖于边界条件。

英文摘要:

In the present paper we study forward Quantum Markov Chains (QMC) defined on Cayley tree. A construction of such QMC is provided, namely we construct states on finite volumes with boundary conditions, and define QMC as a weak limit of those states which depends on the boundary conditions. Using the provided construction we investigate QMC associated with XY-model on a Caylay tree of order two. We prove uniqueness of QMC associated with such a model, this means the QMC does not depend on the boundary conditions.
