石墨烯中的电子流体力学

Electronic hydrodynamics in graphene

Boris N. Narozhny

摘要:

在本文中,我报告了一个教学推导的非常规电子流体动力学在石墨烯的动力学理论的基础上。虽然形式上有效的弱耦合限制,这种方法允许一个非常规的流体动力学系统,这是既不是伽利略-也不是洛伦兹-不变,这样的流体动力学方程不能推断出对称性参数。我推广早期的工作,包括外部磁场,并给出明确的表达式耗散系数,剪切粘度和电导率。我还比较了由此产生的理论与相对论流体力学。

英文摘要:

In this paper I report a pedagogical derivation of the unconventional electronic hydrodynamics in graphene on the basis of the kinetic theory. While formally valid in the weak coupling limit, this approach allows one to derive the unconventional hydrodynamics in the system which is neither Galilean- nor Lorentz-invariant, such that hydrodynamic equations can not be inferred from symmetry arguments. I generalize earlier work to include external magnetic fields and give explicit expressions for dissipative coefficients, the shear viscosity and electrical conductivity. I also compare the resulting theory with relativistic hydrodynamics.
