摘要：

We apply the recently proposed approach of quantum field theory of superradiance to liquid He-4. We find natural, and input-free, explanations of (i) the temperature dependence of the roton gap DELTA(T) and the normal-fluid fraction rho-n/rho, (ii) the microscopic two-fluid structure of superfluid He-4; and (iii) the basic mechanism of vortex formation and the associated critical velocities.
