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。利用图的树结构,给出了Cayley树上量子马尔可夫链的构造。通过这种构造,我们证明了QMC方案中三阶Cayley树上XY模型的相变的存在性.对于给定的相互作用算符$\{K_{<x,y>}\}$族,我们所说的相变是指存在两个准等价的QMC。

英文摘要:

In the present paper we study forward Quantum Markov Chains (QMC) defined on a Cayley tree. Using the tree structure of graphs, we give a construction of quantum Markov chains on a Cayley tree. By means of such constructions we prove the existence of a phase transition for the XY-model on a Cayley tree of order three in QMC scheme. By the phase transition we mean the existence of two now quasi equivalent QMC for the given family of interaction operators $\{K_{<x,y>}\}$.
