Theory of cooling by flow through narrow pores
Dilution chillers cooling heat atoms quantum states
2014/12/20
We consider the possibility of adding a stage to a dilution refrigerator to provide additional cooling by “filtering out” hot atoms. Three methods are considered: (1) effusion, where holes having diam...
