Description
There is a model that includes viscosity at the lambda point in the transition to the superfluid state. This viscosity is expressed in terms of composite operators of dimension 8, but composite operators of dimension 6 are mixed with them. In dynamics, composite operators were almost not considered, but dynamic operators of dimension 6 can be investigated without additional calculations.
