3D非阿贝尔任意子:绝热冷却简并分裂和检测

3D Non-Abelian Anyons: Degeneracy Splitting and Detection by Adiabatic Cooling

Seiji J. Yamamoto, Michael Freedman, Kun Yang

摘要:

三维非阿贝尔任意子已被理论上提出存在于由II型超导体和拓扑绝缘体组成的异质结构中。我们使用来自Bi $_2$ Se $_3$的器件的实际材料参数来定量预测温度和磁场制度,其中实验可能会检测到这些奇异状态的存在通过冷却效应。在适当的参数范围内,当任意子存在时,磁场的绝热增加将导致系统温度的降低。如果不存在任何子,同样的实验将导致加热。

英文摘要:

3D non-abelian anyons have been theoretically proposed to exist in heterostructures composed of type II superconductors and topological insulators. We use realistic material parameters for a device derived from Bi$_2$Se$_3$ to quantitatively predict the temperature and magnetic field regimes where an experiment might detect the presence of these exotic states by means of a cooling effect. Within the appropriate parameter regime, an adiabatic increase of the magnetic field will result in a decrease of system temperature when anyons are present. If anyons are not present, the same experiment would result in heating.
