低维自旋系统中肖特基型Heat capacity

Heat capacity of Schottky type in low-dimensional spin system

Saeed Mahdavifar, Alireza Akbari

摘要:

本文用理论和数值方法研究了低维自旋系统的热容。在只保留两个能态的情况下,系统被映射到两能级系统(TLS)模型。使用低温Lanczos方法,它被证实的行为的$T_{M}$和能隙作为控制参数的函数是相同的,在两个模型研究的结论,可能可以外推到一般情况下的任何系统,具有一个能隙。

英文摘要:

The heat capacity of low-dimensional spin systems is studied using theoretical and numerical techniques. Keeping only two energy states, the system is mapped onto the two -level-system (TLS) model. Using the low temperature Lanczos method, it is confirmed that the behavior of $T_{M}$ and the energy gap as functions of the control parameter is the same in the two models studied; a conclusion that can probably be extrapolated to the general case of any system that possesses an energy gap.
