Alessandra S. Lanotte (LE)11/12/2015, 09:00The dynamical effects of mode reduction in Fourier space for three dimensional turbulent flows is studied. We present fully resolved numerical simulations of the Navier-Stokes equations with Fourier modes constrained to live on a fractal set of dimension D. The robustness of the energy cascade and vortex stretching mechanisms are tested at changing D, from the standard three dimensional...Go to contribution page

Dr Alessandro Mossa (FI)11/12/2015, 09:20In the last two decades active matter has been the object of a surge of theoretical and experimental interest. Apart from the obvious biological relevance, theorists are also specially attracted by the inherently non-equilibrium nature of self-propulsion phenomena. After a quick overview of the theoretical models and experimental systems that are currently under the spotlight, this talk will...Go to contribution page

Axel Cortes Cubero (T)11/12/2015, 09:40We analyse quench processes in two dimensional quantum field theories with infinite number of conservation laws which also include fermionic charges that close a $N=1$ supersymmetric algebra. While in general the quench protocol induces a breaking of supersymmetry, we show that there are particular initial states which ensure the persistence of supersymmetry also for the dynamics out of...Go to contribution page

Volodymyr Chelnokov (Bogolyubov Institute for Theoretical Physics of the National Academy of Sciences of Ukraine)11/12/2015, 10:00Two dimensional U(N) and SU(N) spin models are studied both analytically and numerically to establish the existence of BKT-like phase transitions. In U(N) case a BKT phase transition is found for any value of N. In SU(N) case two BKT-like transitions appear in the model with an adjoint interaction term, if it is large enough, though in the model without the adjoint term only a first order...Go to contribution page

Alessandro Nada (TO)11/12/2015, 10:20We present a novel set of high-precision lattice results for the equation of state of the SU(2) pure Yang-Mills theory in the confining phase. The prediction of a gas of non-interacting, massive glueballs yields a remarkable description of lattice data, provided that a bosonic closed string model is used to derive an exponentially growing Hagedorn spectrum for heavy glueball states. This...Go to contribution page

Dr Daniele Belardinelli (Università di Roma, Tor Vergata)11/12/2015, 10:40Thermal fluctuations and non-ideal multicomponent effects are important ingredients for a proper mesoscale description of a wide variety of flows in soft matter and biological physics [1, 2, 3]. Theoretically, thermally fluctuating mesoscopic flows are most conveniently dealt within the framework of fluctuating hydrodynamics [4]. An important ingredient in this formulation is the...Go to contribution page
