Scope

The title of the XXVI Sitges Conference on Statistical Mechanics was New trends in Statistical Physics. We organized sessions with contributions regarding active matter, biophysics, molecular liquids and colloids, fluids and turbulence, percolation and networks, transport and anomalous diffusion, stochastic processes, fundamentals of statistical physics, and more. With this edition of the Conference we intended to stimulate discussions between physicists and researchers coming from different areas, to favor the interchange and cross-fertilization of ideas, and to deepen the understanding of the open questions in an emerging and innovative field. In this special edition, we celebrated the 50th anniversary of the Conference.
