Why to study superfluid 3He?
I am interested in superfluid 3He because it is
one of a small number of systems that satisfy all the following
conditions.
- It exists in nature.
- One can study it experimentally. The experimental results
can be reproduced.
- It shows nontrivial phenomena. In fact, there is a great number of them.
- There exists a powerful theory which provides quantitative understanding
for most experimental results and predicts many phenomena.
This is the
quasiclassical theory of Fermi liquids.
I believe that superfluid 3He is a paradigm that is
useful for other branches of physics, especially for unconventional
superconductivity.
Note that this is my personal view, and
Grigory Volovik
has a somewhat different emphasis in his research.
