Cavitation on single electron bubbles in liquid helium at small negative pressures

Liquid helium under negative pressure represents a unique possibility for studying the macroscopic quantum nucleation phenomena in condensed media. We analyze cavitation rate of single electron bubbles at low temperatures down to absolute zero. The energy dissipation and sound emission processes result different temperature behavior normal fluid $^{3}\mathrm{He}$ superfluid $^{4}\mathrm{He}$ below thermal-quantum crossover temperature. position rapid line temperature-pressure phase diagram is discussed as well.
