microkelvin cooling
chemistry
Quick Summary
Microkelvin cooling refers to achieving temperatures extremely close to absolute zero, which is -273.15 °C. At these ultra-low temperatures, matter exhibits unusual behaviors not seen at room temperature, such as superconductivity and superfluidity. While molecular motion doesn't entirely cease, there is minimal energy available for transfer as heat. The production of these low-temperature phenomena is the domain of cryogenics.12
