New 'refrigerator' super-cools molecules to nano-Kelvin temperatures（图）
New refrigerator super-cools molecules nano-Kelvin temperatures
2020/4/17
For years, scientists have looked for ways to cool molecules to ultracold temperatures, at which point the molecules should slow to a crawl, allowing scientists to precisely control their quantum beha...
Polarization-preserving confocal microscope for optical experiments in a dilution refrigerator with high magnetic field
Polarization-preserving confocal microscope optical experiments dilution refrigerator magnetic field

We present the design and operation of a fiber-based cryogenic confocal microscope. It is designed as a compact cold-finger that fits inside the bore of a superconducting magnet, and which is a modula...
24 January 2007，While physicists have exploited the thermal properties of magnetic nuclei to reach temperatures as low as 100 pK, these techniques are not suitable for cooling relatively large structu...
