论文摘要
我们研究量子波动对共振附近二维$ P+IP $超氟的影响。在标准范式中，超流体和零密度真空之间的相变是连续的。当考虑到附近共振附近的强量量波动时，连续相变的线在谐振附近的两个多政治点处终止，期望过渡是一阶的。当耦合较强时，发生一阶相变的窗口的大小被证明是很大的。接近一阶的过渡，由于超流体和真空之间的相分离而导致的超流体自我合同。
We study effects of quantum fluctuations on two-dimensional $p+ip$ superfluids near resonance. In the standard paradigm, phase transitions between superfluids and zero density vacuum are continuous. When strong quantum fluctuations near resonance are taken into account, the line of continuous phase transitions terminates at two multicritical points near resonance, between which the transitions are expected to be first-order ones. The size of the window where first-order phase transitions occur is shown to be substantial when the coupling is strong. Near first-order transitions, superfluids self-contract due to phase separations between superfluids and vacuum.
