幂律关联随机矢量势中的狄拉克费米子

Dirac fermions in a power-law-correlated random vector potential

D. V. Khveshchenko

摘要:

我们研究了二维狄拉克费米子在幂律相关随机矢量势下的局域化性质,石墨烯中的“涟漪”效应。通过使用各种技术(低阶微扰理论,自洽玻恩近似,副本,和超对称性),我们使一个可能的情况下,完全本地化的所有电子状态和计算的状态密度。

英文摘要:

We study localization properties of two-dimensional Dirac fermions subject to a power-law-correlated random vector potential describing, e.g., the effect of "ripples" in graphene. By using a variety of techniques (low-order perturbation theory, self-consistent Born approximation, replicas, and supersymmetry) we make a case for a possible complete localization of all the electronic states and compute the density of states.
