论文摘要
我们研究了一个由一个维度量子波动控制的可混杂的不可见的相变的玻色 - 果混合物。我们发现最近被预测的所谓混合气泡是接近平均田间混溶性不知不见的阈值的基态。这些气泡形成了一个混乱的袋,由其中一个组成部分隔开。集体激发反映了气泡形成引起的对称破坏。该系统的部分混乱允许在环形限制中持续潮流。有趣的是,混合气泡的作用像是固有的弱环节,将混合气泡状态的旋转行为与当前在原子应用中的努力联系起来。
We investigate a Bose-Bose mixture across the miscible-immiscible phase transition governed by quantum fluctuations in one dimension. We find the recently predicted so-called mixed bubbles as ground states close to the mean-field miscible-immiscible threshold. These bubbles form a pocket of miscibility, separated by one of the components. The collective excitations reflect the symmetry breaking resulting from the bubble formation. The partial miscibility of the system allows for persistent currents in an annular confinement. Intriguingly, the mixed bubble acts like an intrinsic weak link, connecting the rotational behavior of the mixed bubble state to current efforts in atomtronic applications.
