形变石墨烯中Dirac流体的电子粘性

On the electronic viscosity of a Dirac fluid in deformed graphene

Sergei Sergeenkov, Marcel Ausloos

摘要:

通过在Dirac方程中引入应变梯度和速度梯度分别等效为赝磁场和赝电场,讨论了形变石墨烯中Dirac流体的电子粘性性质.由此分析地确定,动态剪切粘度系数随着所施加的应变而显著减小。

英文摘要:

We discuss the properties of the electronic viscosity of a Dirac fluid in deformed graphene by introducing a strain and velocity gradient as equivalent to a pseudo-magnetic and pseudo-electric field respectively into the Dirac equation. It is thereby analytically established that the dynamic shear viscosity coefficient substantially decreases with the applied strain.
