Clear Explanation of the Physics Behind ³He/⁴He Dilution Refrigerators: Reaching Absolute Zero

In this video, Dr. Jacob Hudis explains the fascinating properties of helium isotopes ³He and ⁴He. He then delves into the phase diagram for water and ⁴He, comparing the two and illustrating how the latent heat of phase change is used to cool substances without changing the temperature of the cooling agent, merely altering its phase. Dr. Hudis further elucidates the phase diagram of the ³He/⁴He mixture, revealing how the phase transition from dilute to concentrated phase of ³He powers this quantum cooling device. This technology relies on the unique quantum mechanical properties of helium, showcasing an incredible feat of scientific innovation. Join Dr. Hudis on a journey to uncover the physics behind this remarkable device.
