外磁场中具有化学势的三维重狄拉克费米子:电流-电流关联函数

3D massive Dirac fermions with chemical potential in external magnetic field: Current-current correlation function

Elena Apresyan

摘要:

在非量子化磁场存在下,费米子系统对外部规范场的响应由电流-电流关联函数$Π_{μν}({\bf B})$确定。研究了$2D$维Dirac电子系统,计算了存在磁场$B$、化学势$η$和能隙$m$时的电流-电流关联函数.

英文摘要:

The response of fermionic system to external gauge fields in presence of non-quantized magnetic field is determined by current-current correlation function $Π_{μν}({\bf B})$. We study $2D$ dimensional Dirac electron system and calculate current-current correlation function in a presence of magnetic field $B$, chemical potential $η$ and gap $m$.
