论文摘要
负压下的液态氦是研究浓缩培养基中宏观量子成核现象的独特可能性。我们分析低温下至绝对零的单电子气泡的量子气量速率。能量耗散和声音排放过程导致量子气氮在正常流体中的不同温度行为$^3 $ He和Superfluid $^4 $ He He低于热量Quantum交叉温度。还讨论了快速成核线在温度压力相图中的位置。
Liquid helium under negative pressure represents a unique possibility for studying the macroscopic quantum nucleation phenomena in condensed media. We analyze the quantum cavitation rate of single electron bubbles at low temperatures down to absolute zero. The energy dissipation and sound emission processes result in the different temperature behavior of quantum cavitation rate in normal fluid $^3$He and superfluid $^4$He below the thermal-quantum crossover temperature. The position of rapid nucleation line in the temperature-pressure phase diagram is discussed as well.
