手性麦克斯韦恶魔
A chiral Maxwell Demon
摘要：
我们研究了手征性对在含有局域杂质的量子霍尔棒中实现的麦克斯韦妖的性能的影响。在一个随机热力学描述，我们调查的能力，这样的恶魔驱动电流对偏置。我们表明，恶魔执行的能力是直接相关的，它的能力，从系统中提取信息。提出的麦克斯韦妖的关键特征是量子霍尔系统的拓扑性质。当磁场反向时，在局域态处感受到的电子相互作用的不对称性与我们考虑将这种状态与霍尔边缘模式连接的能量依赖（和不对称）隧穿势垒的事实相结合，允许恶魔正常工作。
英文摘要：
We investigate the role of chirality on the performance of a Maxwell demon implemented in a quantum Hall bar with a localized impurity. Within a stochastic thermodynamics description we investigate the ability of such a demon to drive a current against a bias. We show that the ability of the demon to perform is directly related to its ability to extract information from the system. The key features of the proposed Maxwell demon are the topological properties of the quantum Hall system. The asymmetry of the electronic interactions felt at the localized state when the magnetic field is reversed joined to the fact that we consider energy dependent (and asymmetric) tunneling barriers that connect such state with the Hall edge modes allow the demon to properly work.
