cryogen-free dilution refrigerator system

使用低温恒温器，量子系统或混合量子系统将被冷却到100mK以下，以增加它们的相干时间，并实现冷却到它们的量子力学基态。例如，该装置将用于冷却固态材料中与自旋耦合的机械振荡器，并为机械谐振器的自旋冷却提供先决条件。此外，还将研究各种耦合系统的冷却效率，以测试不同热浴池冷却效率的热力学极限。低温恒温器还将用于在高磁场下将各种自旋系统冷却到低温，以延长其弛豫时间。

With the cryostat, quantum systems or hybrid quantum systems will be cooled to below 100mK to increase their coherence times and to achieve cooling to their quantum mechanical ground state. As an example, the device will be used to cool down mechanical oscillators that are coupled to spins in solid-state materials and to provide a prerequisite for spin-cooling of mechanical resonators. Furthermore, the cooling efficiency of various coupled systems will be investigated to test the thermodynamic limits of cooling efficiency for different thermal baths. The cryostat will also serve to cool various spin systems at high magnetic fields to low temperatures in order to extend their relaxation time.
