Título: Percolation in 2d coarsening dynamics

Apresentador: Marco Picco (LPTHE-CNRS e Université Paris 6)

Resumo: After a rapid quench to a subrcitical temperature, magnetised systems like the 2d Ising model are expected to evolve towards a completely magnetised system. Recent works have shown that in fact, under some conditions, the system will end up, with a finite probability, in a stripe states. The probability of having these stripe states is related to percolation exponents. In this talk, I will present results with the aim to characterise this behavior. In particular I will show that there exist a new time scale describing the appearance of percolating states at the origin of the final stripe states.
