论文摘要
受模拟重力的启发，先前已经在Bose-Einstein冷凝物（BEC）中研究了超沉淀。在这项工作中，我们通过向系统引入耗散来重新审视这个问题。在确定了耗散性BEC中量子涡度的可能性之后，我们分析了基本激发的传播并证明了超级模式的存在，可以根据``抗粒子''的耗散来解释这些模式。我们的发现支持了围绕量子量子量的超级散射的可能性，并在未来的实验中支持散射的可能性。
Inspired by Analogue Gravity, superradiance has been previously investigated in Bose-Einstein condensates (BECs). In this work, we revisit this problem by introducing dissipation to the system. After establishing the possibility of quantum vortices in dissipative BECs, we analyze the propagation of elementary excitations and demonstrate the existence of superradiant modes which can be interpreted in terms of the dissipation of ``antiparticles". Our findings support the possibility of superradiant scattering around dissipative quantum vortices and paves the way for future experimental realization of the phenomenon.
