Studies of Crystalline and Multilayer Two-Dimensional Systems

小行星9503814 PI将从理论上研究二维电子系统，特别是量子霍尔制度中的维格纳晶体和分层系统。 将研究无序势对经典晶体的静态和动态性质以及在非常强的磁场中的晶体的影响，包括基态的相关函数、噪声谱和AC电导率。 他还将从理论上研究光致发光（实验探针），量子效应，双层量子霍尔系统，激发态和杂质效应。 PI将对氦表面和强磁场中的半导体系统中的二维电子系统进行理论研究。 这类系统特别令人感兴趣，因为它们不能用传统的理论方法完全解释。 这个PI起着重要的作用，有助于必须开发新的方法来理解这样的系统。 他以其研究的广度和使用的方法的多样性而闻名。 他的部分工作将特别有助于解释最近在这些系统上的几个实验。 ***

9503814 Fertig The PI will investigate theoretically two-dimensional electron systems, specifically the Wigner crystal and layered systems in the quantum Hall regime. The effects of a disorder potential on the static and dynamic properties of classical crystals, as well as crystals in very strong magnetic fields, will be studied, including correlation functions in the ground state, noise spectra, and AC conductivity. He will also theoretically study photoluminescence (an experimental probe), quantum effects, double layer quantum Hall systems, excited states, and impurity effects. %%% The PI will conduct theoretical research on two-dimensional electron systems, as found on the surface of helium and in semiconducting systems in strong magnetic fields. Such systems are of special interest because they cannot be completely explained by traditional theoretical methods. This PI plays an important part in contributing to the new methods that must be developed to understand such systems. He is known for the breadth of his research and the variety of methods he uses. Parts of his work will be especially helpful in interpreting several recent experiments on these systems. ***
