He is best known for his work in statistical mechanics.

If so, what does statistical mechanics tell us about the arrow of time?

Everything in the following article also applies to statistical mechanics.

He is best known for his work in statistical mechanics and quantum many body theory.

One would need to use statistical mechanics to do what you have in mind, which is considerably more complex.

He also applied these methods to problems of statistical mechanics.

His main research is in the field of non-equilibrium statistical mechanics.

He also was important to particle physics, and statistical mechanics.

The later theory of statistical mechanics, however, is symmetric in time.

However, they have strong connections with quantum field theory and statistical mechanics.
