Quantum cavitation in liquid helium: Dissipation effects

We have investigated the quantum-to-thermal cavitation crossover temperature T* in liquid helium using a functional-integral method in conjunction with a density functional description of the liquid. Dissipation is taken into account introducing a semiphenomenological Rayleigh's dissipation fun...
