麻省理工学院的物理学家首次记录了超流体中的热晃动。 MIT Physicists Record First-Ever Heat Sloshing in Superfluid.

麻省理工学院的物理学家成功捕捉到了“第二声音”的第一张图像，这是冷却到极低温度时超流体内的一种波状热运动。 MIT physicists have successfully captured the first images of 'second sound', a wave-like movement of heat within a superfluid when cooled to extremely low temperatures. 以前仅在少数材料中观察到这种现象，它揭示了热量如何来回“晃动”，而与材料的物理颗粒无关。 Previously only observed in a small number of materials, this phenomenon reveals how heat can "slosh" back and forth, independent of a material's physical particles. 这项研究将帮助物理学家了解热量如何通过超流体和相关材料（包括高温超导体和中子星）移动。 This research will aid physicists in understanding how heat moves through superfluids and related materials, including high-temperature superconductors and neutron stars.
