Prof. Uwe-Jens Wiese (Bern University)11/12/2015, 11:30The real-time evolution of large open quantum spin systems, whose dynamics are entirely driven by dissipative couplings to an environment, is studied in two and three spatial dimensions. Dissipative processes with Hermitean quantum jump operators lead from the ordered phase of the Heisenberg or XY-model into a disordered phase at late times. The corresponding Lindblad equation is solved using...Go to contribution page

Enzo Orlandini (P)11/12/2015, 12:10Dispersions of colloidal particles in liquid crystals are nowadays a subject of intensive studies due to their potential as novel and versatile metamaterials with important applicative avenues such as digital-ink technologies, biosensors and optical devices. In this talk I will report theoretical results, based on lattice Boltzmann simulations, on a novel method to manipulate the...Go to contribution page

Federico Corberi (SA)11/12/2015, 12:40Condensation is the phenomenon whereby a finite fraction of some quantity, e.g. a particle density, concentrates into a small region of phase-space, as in the paradigmatic example of a vapor transforming into a liquid when crossing a phase-transition. It is observed in a number of different models, related to magnetic properties, gravity, mass transport and other issues. A different...Go to contribution page

Prof. Marco Zannetti (Università di Salerno)11/12/2015, 13:00Observing fluctuations of an extensive quantity is alike to put a constraint on the system. Though it may sound odd, the statement is of general validity, with far reaching consequences both in equilibrium and out of equilibrium. Its meaning becomes precise in the framework of large deviation theory. As an example of the connection, in the talk it will be shown that the so called...Go to contribution page
