对自旋玻璃基态临界点的挑战

A challenge for critical point of spin glass in ground state

Masayuki Ohzeki

摘要:

本文在对偶分析的基础上计算了包括自旋玻璃在内的无规自旋系统的基态临界点。对偶性分析是一种深刻的方法,即使对于自旋玻璃,也可以在有限温度下得到临界点的精确位置。我们提出了一个单一的等式来确定在基态的临界点,从几个猜测。这个等式确实可以给出几种晶格上键稀释伊辛模型临界点的精确位置,并为进一步分析自旋玻璃中的基态提供了依据。

英文摘要:

We show several calculations to identify the critical point in the ground state in random spin systems including spin glasses on the basis of the duality analysis. The duality analysis is a profound method to obtain the precise location of the critical point in finite temperature even for spin glasses. We propose a single equality for identifying the critical point in the ground state from several speculations. The equality can indeed give the exact location of the critical points for the bond-dilution Ising model on several lattices and provides insight on further analysis on the ground state in spin glasses.
