论文摘要
我们通过精确的路径综合蒙特卡洛模拟来研究有限温度排斥两组分子混合物的磁性行为。新型算法是针对两种组成部分的自由能和化学潜力实施的。磁敏感性的结果表明，相位分离条件并未从零温度情况下改变。这与基于近似理论的先前预测相矛盾。我们还确定了化学电位的温度依赖性和实验相关平衡混合物的接触参数。
We investigate the magnetic behavior of finite-temperature repulsive two-component Bose mixtures by means of exact path-integral Monte-Carlo simulations. Novel algorithms are implemented for the free energy and the chemical potential of the two components. Results on the magnetic susceptibility suggest that the conditions for phase separation are not modified from the zero temperature case. This contradicts previous predictions based on approximate theories. We also determine the temperature dependence of the chemical potential and the contact parameters for experimentally relevant balanced mixtures.
