论文摘要
我们研究了一维有吸引力的玻色 - 玻璃混合物中弱相互作用的均匀液体的低温热力学。首先，我们详细研究了驱动液体到气体过渡的两种不同的热机制，动力学不稳定性和蒸发，并绘制相图。然后，我们计算液体的主要热力学量，例如化学电位，棕褐色的接触，绝热声音速度和恒定体积的比热。热力学数量对温度的强依赖性可用作量子液体实验的精确温度探针。
We study the low-temperature thermodynamics of weakly-interacting uniform liquids in one-dimensional attractive Bose-Bose mixtures.~The Bogoliubov approach is used to simultaneously describe quantum and thermal fluctuations. First, we investigate in detail two different thermal mechanisms driving the liquid-to-gas transition, the dynamical instability and the evaporation, and we draw the phase diagram. Then, we compute the main thermodynamic quantities of the liquid, such as the chemical potential, the Tan's contact, the adiabatic sound velocity and the specific heat at constant volume. The strong dependence of the thermodynamic quantities on the temperature may be used as a precise temperature probe for experiments on quantum liquids.
