Recent Development
Superfluids are one of the most famous discoveries in the 20th century. It opens many new fields of science and is still today the hot topic in researches. As has been intimated in our discussion of superfluids, a reason why they are so important is that they allow us to see quantum mechanical behavior macroscopically. So these materials constitute a medium that physicists can use to directly analyze quantum theory. There are several behaviours that can be said to be the hallmarks of superfluidity simply because they do not occur anywhere else in the nature. But still, superfluid is a new concept to us. Over the past eight decades we have been able to understand very little about it and still many hidden applications are in the lap of nature and hopefully in future we will be able to gain much more from it.
