10:15 BIOPHYS (1)

Computer simulations of polymer physics and the 3D structure of the human genome Chromosomes in mammalian cells have a complex spatial organization serving vital functional purposes. We are showing that their 3D structure can be derived with high accuracy, and its molecular determinants identified, by use of polymer physics combined with advanced, massive computer simulations and high-throughput experimental data analysis. Chromosomes have a hierarchical architecture made of domains-within-domains, deeply linked to gene regulation. Predictions on the effects of genomic mutations are now confirmed by experiments. Our results are helping progressing the basic understanding of genome function and structure, as well as new diagnostic tools for diseases linked to chromatin misfolding, such as congenital disorders and cancer.

11:35 QFT_HEP

I will present the foreseen activity and the computational needs of Iniziativa Specifica QFT-HEP (LNF node, Maria Paola Lombardo). The research includes: 1) A quantitative study of the quark gluon plasma up to temperatures \simeq 1 Gev with a realistic matter content (two almost physical light flavors, and a strange and a charm quark). The main observables will be the Equation of State and topological susceptibility. The studies of topological susceptibilities with dynamical quarks are just starting, and the group has presented the first quantitative results with a dynamical charm and Wilson fermions. 2) New techniques, and their applications to the computation of spectral functions and transport coefficients. The analytic continuation from the imaginary time (used on the lattice), to the real time - or, equivalently, to the frequency space poses specific problems: the LNF activities will concentrate on the developments and checks of new methodologies for the analytic continuation, in interaction with the Bari group. 3) Continuity between a strongly interacting quark gluon plasma and the cold conformal window of QCD.

12:15 Neutron Star Matter (NeuMatt)

The detection of GWs associated with the merger of two neutron stars offers a new important tool to test the Equation of State of matter at very high densities. Preliminary studies have indicated the possibility of discriminating among the various theoretically possible EoSs by analysing the GW signal before and after the merger. Morever, the merger of two neutron stars is supposed to be at the origin of the short Gamma Ray Bursts: a detailed analysis of the effects of the EoS on the merger will provide crucial information also to the physics and the astrophysics of these explosive phenomena. To study the impact of the EoS on the merger state-of-the-art codes describing in full GR the process of merger are needed. These codes are high demanding on the computational side. This research is at the core of the IS NeuMatt.

12:20 Cosmological computing with InDark

The goal of InDark is to investigate crucial aspects of the standard cosmological model and their connection with particle physics. The project focuses on inflation in the early Universe, the nature of dark matter and the nature of dark energy, also in terms of scenarios of modified gravity, as well as on neutrino cosmology. Particular emphasis is given to the present-day and future observations of the Cosmic Microwave Background (CMB) radiation, the study of the Large-Scale Structure (LSS) of the Universe through present and future surveys. InDark research topics are in significant need supercomputing power, for theoretical modelling, simulations and model to data comparisons. I will briefly present the current ongoing computational activities and discuss forecastable future demand.
