相对论费米子在$2+1$维中的扭转响应

Torsional response of relativistic fermions in $2+1$ dimensions

Manuel Valle

摘要:

本文研究了在$2+1$维中与挠率最小耦合的狄拉克费米子理想气体的平衡配分函数。我们表明,能量动量张量再现霍尔粘度和其他宇称违反条款的一阶扭转。我们还考虑了本构关系的修改,并对相应的相容性进行了分类。构造了一个与平衡态零熵产生相一致的熵流。

英文摘要:

We consider the equilibrium partition function of an ideal gas of Dirac fermions minimally coupled to torsion in $2+1$ dimensions. We show that the energy-momentum tensor reproduces the Hall viscosity and other parity violating terms of first order in the torsion. We also consider the modifications of the constitutive relations, and classify the corresponding susceptibilities. An entropy current consistent with zero production of entropy in equilibrium is constructed.
