Molecular fridge can reach millikelvin

by Simon Hadlington

Scientists have laid the foundations for a high-performance ‘molecular fridge’ capable of reaching temperatures within a few thousandths of a degree of absolute zero with a high degree of efficiency. Such ultracoolers could have applications in areas such as ultra-low temperature physics, where alternative technologies such as those that rely on expensive and rare helium-3 could be unsuitable or too costly.
