Sherrington-Kirkpatrick模型中的自由能涨落和混沌

Free energy fluctuations and chaos in the Sherrington-Kirkpatrick model

T. Aspelmeier

摘要:

严格地证明了Sherrington-Kirkpatrick模型中自由能的样品间涨落Δ F_N与键混沌有关。通过这种连接,波动变得可以通过复制方法进行分析。对键混沌的复制计算表明,控制涨落随系统尺寸N增长的指数μ,即Δ F_N N^μ,受μ ≤ 1/4的限制.

英文摘要:

The sample-to-sample fluctuations Delta F_N of the free energy in the Sherrington-Kirkpatrick model are shown rigorously to be related to bond chaos. Via this connection, the fluctuations become analytically accessible by replica methods. The replica calculation for bond chaos shows that the exponent mu governing the growth of the fluctuations with system size N, i.e. Delta F_N N^mu, is bounded by mu <= 1/4.
