Europe/Rome 2019-12-12 11:00:00 2019-12-12 12:00:00 Condensed Matter and Statistical Physics Seminar: Propagation of Information in Turning Flocks of Starlings Animal groups on the move are a paradigmatic example of collective behavior in social species in which the tools of statistical physics can be fruitfully used. I will present an experimental and theoretical study of spontaneous rapid collective turns in natural flocks of starlings in which we find a sound-like propagation of the turning decision across the flock with no damping of information. This is in contrast with standard theories of collective animal behavior based on alignment, which predict a much slower, diffusive spread of information. We propose a novel theory for propagation of orientation in flocks whose key ingredient is the existence of a conserved spin current generated by the gauge symmetry of the system. Moreover, our analysis reveals that spontaneous collective turns are triggered by persistent localized fluctuations in the travel direction of some individuals in the flock. Two crucial ingredients which enhance the effect of such noise leading to collective changes of state are: the non-symmetric nature of interaction between individuals and the presence of heterogeneities in the topology of the interaction network.

Europe/Rome 2019-12-17 11:00:00 2019-12-17 12:00:00 Joint ICTP/SISSA Statistical Physics Seminar: From Quantum Algorithms to Out-of-Equilibrium Phenomena in Interacting Trapped-Ion Spin Chains This is a TQT (Theory of Quantum Technologies) Event. Laser cooled trapped ions offer unprecedented control over both internal and external degrees of freedom at the single-particle level. They are considered among the foremost candidates for realizing quantum simulation and computation platforms that can outperform classical computers at specific tasks. In this talk I will show how linear arrays of trapped 171Yb+ ions can be used as a versatile platform for studying out-of-equilibrium strongly correlated many-body quantum systems. In particular I will present our observation of a new type of out-of-equilibrium dynamical phase transition in a spin system with over 50 spins [1]. Moreover, I will show our latest efforts towards scaling up the trapped-ion quantum simulator [2] using a cryo-pumped vacuum chamber where we can trap more than 100 ions indefinitely. The reliable production and lifetime of large linear ion chains enabled us to use up to 40 trapped-ion qubits to observe real-time domain wall confinement in an interacting spin chain [3, 4] and to implement a Quantum Approximate Optimization Algorithm (QAOA) to approximate the ground state energy of a transverse field Ising model [5].

Europe/Rome 2020-04-06 08:00:00 2020-04-09 22:00:00 Dissipation Mechanisms in Nano/Mesoscale Tribological Systems | (smr 3435) Nano/mesoscale mechanical and rheological response with dissipation has become, thanks to the very broad range of experimental/theoretical approaches, a novel local diagnostic and even spectroscopic tool, as well as a playground of sophisticated non-equilibrium statistical physics. The physics of nanoscale mechanical dissipation is relevant to sliding nanofriction, to technological themes such as lubrication or finger-touchscreen friction, to soft and granular matter, to nanofrictional emulation in optical lattices, to active matter, to quantum and classical processes in noncontact AFM, and beyond. Between condensed matter physics, nanomechanics, materials science and engineering, this interdisciplinary area is of considerable conceptual value as a modern subject in non-equilibrium physics, and of the potential relevance of neighbouring fields such as fatigue, wear, lubrication, rheology, and biomechanics. As is well established in ICTP Trieste since 1995, we will collect the world community active in these fields, including groups in emerging countries, mixing theoretical, simulation and experimental highlights, and identifying future directions of motion of
research in this lively arena. Topics:     From dissipation to superlubricity     Atomistic friction of 2D layered materials     Nanomanipulation and dynamics of nano-objects at surfaces     Tribology of confined systems and lubricants under shear     Frictional dynamics in soft and active matter     Friction in powders and granular systems     Fundamentals of friction theory     Electronic, magnetic and quantum friction     Surface and bulk  processes and transitions detected by noncontact AFM dissipation     Tribochemistry, triboelectricity, biotribological effects     Trends in experimental and computational techniques Participants are encouraged to submit abstracts of proposed poster contributions. A number of short oral presentation slots will be available for some of them upon selection. Speakers: A. BENASSI, Chiesi Farmaceutici, Italy R.
