C3: Statistical Physics

C3: Statistical Physics

The Commission on Statistical Physics (C3) was established by the International Union of Pure and Applied Physics in 1945 to promote the exchange of information and views among the members of the international scientific community in the general field of Statistical Physics.


The C3 Commission is pleased to announce that the Young Scientist Award for 2016 will be awarded during STATPHYS26 to Lisa Manning and Martin Lenz.

Lisa Manning

Lisa Manning

In recognition of her outstanding statistical physics contributions to the fields of granular materials, jamming, and biological cell dynamics.

Short Biography:

Manning has become a clear leader in the community studying glassy dynamics and jamming, and has also established the importance of these phenomena to biological tissues. In glasses, she has used random matrix theory to uncover universal vibrational properties, and has identified soft vibrational modes as harbingers of local failure. In biology, she has explored the competition between cell-­‐cell adhesion and cortical tension to understand surface tension at the tissue level. Further, she discovered that this competition controls a new rigidity transition in tissues, a startling new member of the jamming transition family that is relevant to asthma and likely also to embryogenesis, tumorigenesis, and wound healing. 


Martin LenzMartin Lenz

For his remarkable creativity in using active processes in living cells as a rich source  of new ideas in statistical physics. At the same time, he shows how these ideas can inspire new thinking in biology proper.

Short Biography:

Lenz’ main contributions concern two quite different but ultimately related areas: the structure and dynamics of the cytoskeleton on the one hand, and the mechanics of protein-­‐induced remodelling of the cell membrane on the other hand. Both of these problems involve understanding how non-­‐equilibrium driving forces establish the structure of the cell. In these problems, the existing knowledge of the biological actors at the molecular scale is still only partial, and Lenz has displayed great subtlety in producing robust theoretical results in sensitive to unknown molecular details.



The Boltzmann Medal

– Boltzmann Ceremony & Presentation: July 24(Wed), 2013

The Boltzmann Award was instituted by the Commission on Statistical Physics (C3) of the IUPAP to honor outstanding achievements in Statistical Physics. It is presented by the Commission at the STATPHYS meeting. The award consists of a glided medal (the Boltzmann Medal) with the inscription of Ludwig Boltzmann.

The C3 Commission is pleased to announce that the Boltzmann Medal has been awarded during STATPHYS25 to:

Giovanni Jona-Lasinio

Giovanni Jona-Lasinio: For his seminal contributions to spontaneous symmetry breaking in particle physics and the theory of non-equilibrium fluctuations.




Harry SwinneyHarry Swinney: For his ingenious and challenging experiments which have had a large impact on many areas of statistical physics.




And the most recent Young Scientist Prize:

Takahiro SagawaTakahiro Sagawa: For developing a comprehensive theoretical framework to characterize the thermodynamics of nonequilibrium systems with feedback control.



Kazumasa TakeuchiKazumasa Takeuchi: For his outstanding experiments on fluctuation properties of growing interfaces in turbulent liquid crystals.
