长程相互作用下Ising联系矩阵的反问题

Inverse problem for Ising connection matrix with long-range interaction

Leonid Litinskii, Boris Kryzhanovsky

摘要:

本文研究了d维超立方体格上的Ising系统,并解决了一个反问题,即当我们知道Ising连接矩阵的特征值谱时,我们必须确定它的相互作用常数。此外,我们定义的限制,允许一个随机数序列是一个连接矩阵谱。我们使用先前获得的解析表达式的伊辛连接矩阵的本征值占一个任意的长程相互作用和假设周期性的边界条件。

英文摘要:

In the present paper, we examine Ising systems on d-dimensional hypercube lattices and solve an inverse problem where we have to determine interaction constants of an Ising connection matrix when we know a spectrum of it eigenvalues. In addition, we define restrictions allowing a random number sequence to be a connection matrix spectrum. We use the previously obtained analytical expressions for the eigenvalues of Ising connection matrices accounting for an arbitrary long-range interaction and supposing periodic boundary conditions.
