Phase-ordering and percolation
Nell'ambito dei seminari teorici di Gruppo IV, il giorno 17 Gennaio 2018, alle ore 14:30, in aula 0M03, il prof. Federico Corberi, (Università di Salerno)
terrà un seminario dal titolo:
"Phase-ordering and percolation"
Abstract
After reviewing some well known facts about phase-ordering - the process whereby an ordered phase is built out of a disordered one when a ferromagnetic system is quenched from above to below the critical temperature - I will present some recent findings in two dimensions showing the existence, next to the growing domains whereby local order is established, of a fractal object with the topology of the critical cluster of random percolation. I will discuss how these two radically different structures develop and coexist in the system and the rather broad generality of the phenomenon withrespect to different models, lattices, kinds of quenched disorder etc.
