Welcome to the web pages of the Statistical and Nonlinear Physics Division (SNPD). The SNPD is a division of the European Physical Society (EPS) that represents and provides a forum for scientists interested in statistical and nonlinear physics, complex systems and interdisciplinary applications (pictures courtesy of P. Manneville and A.-L. Barabasi).

List of Board members of SNPD. Many thanks to Paul Manneville whose term as board member of EPS-SNPD ended in 2019.

**The 2019 EPS Statistical and Nonlinear Physics Prize has been awarded to Sergio Ciliberto (ENS Lyon) and Satya Majumdar (Paris-Sud). The prize award ceremony was on 8 May 2019 in Stockholm during the EPS-Nordita conference "Statistical Physics of Complex Systems". ---- Photos from the award ceremony in Stockholm ----- Long citation of the prize.**

**Sergio Cilberto is honored "for his seminal contributions over a wide range of problems in statistical and nonlinear physics, in particular for performing groundbreaking new experiments testing Fluctuation Theorems for injected power, dissipated heat, and entropy production rates, as well as investigating experimentally the connection between dissipated heat and the Landauer bound, thus demonstrating a link between information theory and thermodynamics".**

**Satya Majumdar is honored "for his seminal contributions to non-equilibrium statistical physics, stochastic processes, and random matrix theory, in particular for his groundbreaking research on Abelian sandpiles, persistence statistics, force fluctuations in bead packs, large deviations of eigenvalues of random matrices, and applying the results to cold atoms and other physical systems".**

** ****-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------**

** ****The 2019 EPS-SNPD Early Career Prize went to Karel Proesmans (Hasselt) and Valentina Ros (ENS Paris). ----- Long citation of the prize.**

**Karel Proesmans is honored "for his outstanding research contributions in the field of stochastic thermodynamics, in particular his work dealing with optimization protocols for thermal engines, as well as his work on thermodynamic uncertainty relations for discrete-time and periodically driven systems".**

**Valentina Ros is honored "for her outstanding research contributions in quantum and classical disordered systems, explaining new ways in which those systems can break ergodicity and fail to equilibrate, and her investigations of rough, high-dimensional landscapes emerging in this context".**

**Congratulations to all prize winners!** We also thank the scientific community for the large number of excellent nominations received.

The prizes are awarded by EPS every 2 years:

1. **EPS**** Statistical and Nonlinear Physics Prize**** **The EPS Statistical and Nonlinear Physics Prize is awarded by EPS for outstanding research contributions in the area of statistical physics, nonlinear physics, complex systems and complex networks. The prize winner will have made ground-breaking and agenda setting contributions for the development of this field. The prize can be shared by up to 2 persons. The prize consists of a glass trophy and a cash sum. Prize winners can have any nationality.

2. **EPS****-SNPD Early Career Prize**

This prize is awarded to an early career scientist (defined as having obtained his/her PhD less than 6 years ago at the time of nomination) who has made outstanding research contributions to an area of statistical physics, nonlinear physics, complex systems, or complex networks, as evidenced by a top quality and highly cited paper in an international journal. The prize can be shared by up to 2 persons. The prize consists of a glass trophy and a cash sum. Prize winners can have any nationality.

**The next prizes will be awarded in 2021.** The prize selection committee consists of the current board members of the Statistical and Nonlinear Physics Division of EPS in consultation with external experts. The 2019 prizes were awarded during the **EPS conference "Statistical Physics of Complex Systems" at Nordita/Stockholm 7-11 May 2019. **

**History**: The above prizes were created by EPS in 2017 and are awarded every 2 years.

The **previous prize winners** (in 2017) were Peter Grassberger, Itamar Proccacia (EPS Statistical and Nonlinear Physics Prize) and Edgar Roldan, Laura Forni (EPS-SNPD Early Career prize).

- to stimulate the interest of young scientists in the field of statistical physics, nonlinear physics, and complex systems
- to organize and support conferences and workshops
- to maintain contacts with related divisions within EPS
- to communicate with similar organizations worldwide

Areas of research

Research areas represented by the division include (but are not restricted to)

- nonequilibrium statistical physics .
- complex networks
- nonlinear dynamical system
- chaos and turbulence
- stochastic modelling
- spin glasses and disordered quantum systems
