理论上预测，在二维电子气的量子霍尔区，能斯特系数被强烈抑制，热导被量子化。能斯特效应是在x方向的温度偏置和z方向的磁场作用下，y方向的热磁电动势的感应。利用循环边缘电流对能斯特效应的量子本质进行了分析，并用数值方法进行了验证。本系统是非平衡稳态的物理实现。(C)2005爱思唯尔有限公司。保留所有权利。
It is theoretically predicted that the Nernst coefficient is strongly suppressed and the thermal conductance is quantized in the quantum Hall regime of the two-dimensional electron gas. The Nernst effect is the induction of a thermomagnetic electromotive force in the y-direction under a temperature bias in the x-direction and a magnetic field in the z-direction. The quantum nature of the Nernst effect is analyzed with the use of a circulating edge current and is demonstrated numerically. The present system is a physical realization of the non-equilibrium steady state. (C) 2005 Elsevier Ltd. All rights reserved.
