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
I believe that superfluid 3He is a paradigm that is
useful for other branches of physics, especially for unconventional
- 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.
Note that this is my personal view, and
has a somewhat different emphasis in his research.
