【 摘 要 】

We discuss the Berry curvature calculations of the Hall viscosity for the Fermi-liquid-like state, i.e., a Fermi-liquid state of underlying composite particles of the Hall system. We conclude, within assumptions made, that in the linear response, with small deformation of the system and in the thermodynamic limit, the Hall viscosity takes the value characteristic for the Laughlin states. We present arguments that the value is the same even for general deformations in the same limit.
