论文摘要
提高材料的温度会增强颗粒的热运动。热能的这种增加通常会导致固体熔化成流体,并最终使液体变成物质的气相。在这里,我们研究了偶极量子流体的有限温度物理学,并发现与这种一般现象学的令人惊讶的偏差。特别是,我们描述了如何从接近零温度中加热偶极超流体,从而诱导相过渡到具有损坏的翻译对称性的超olid状态。预测的效果与对超低dyprosium原子的实验测量相符,这为探索偶极量子液的异常热力学打开了大门。
Raising the temperature of a material enhances the thermal motion of particles. Such an increase in thermal energy commonly leads to the melting of a solid into a fluid and eventually vaporises the liquid into a gaseous phase of matter. Here, we study the finite-temperature physics of dipolar quantum fluids and find surprising deviations from this general phenomenology. In particular, we describe how heating a dipolar superfluid from near-zero temperatures can induce a phase transition to a supersolid state with a broken translational symmetry. The predicted effect agrees with experimental measurements on ultracold dysprosium atoms, which opens the door for exploring the unusual thermodynamics of dipolar quantum fluids.
