一维有限程多势垒中的相变
Phase transitions in a one-dimensional multibarrier potential of finite range
摘要：
我们以前研究了一维势的性质，$N$等距相同的障碍，在（固定）有限区间有限和无限$N$。有人观察到，散射和光谱特性敏感地依赖于比例$c$的间隔宽度的障碍（即使在限制$N \to \infty$）。我们在这里计算的特定的热量系综这样的系统，并表明，有这个参数的关键依赖，以及对温度，强烈暗示的相变。
英文摘要：
We have previously studied properties of a one-dimensional potential with $N$ equally spaced identical barriers in a (fixed) finite interval for both finite and infinite $N$. It was observed that scattering and spectral properties depend sensitively on the ratio $c$ of spacing to width of the barriers (even in the limit $N \to \infty$). We compute here the specific heat of an ensemble of such systems and show that there is critical dependence on this parameter, as well as on the temperature, strongly suggestive of phase transitions.
