Physical systems characterized by stick-slip dynamics often display avalanches. Regardless of the diversity of their microscopic
structure, these systems are governed by a power-law distribution of avalanche size and duration. We focus instead on the
interevent times between avalanches and show that, unlike their size and duration, the distribution of interevent times is able...
The study of relativistic fluids apply to several fields of modern physics,
covering many different scales, from astrophysics, to atomic scales (e.g. in the study of effective 2D systems such as graphene) and further down to subnuclear scales (e.g. quark-gluon plasmas).
In particular, the experimental results from heavy-ion collisions at RHIC and LHC, with the first experimental...
In this seminar we briefly review the current status of tensor network methods, a numerical techniques for performing efficient classical numerical simulations of quantum many-body systems. Tensor network methods promise to become a powerful tool for benchmarking and results verification of future quantum simulations and computations. We will review some of the possible applications of this...
Human groups face with problem-solving through autonomous and self-organized processes of collective decision-making. Among scientists, statistical physicists have studied large collective systems in nature (make examples) and, in particular, how the dynamics of collective decision-making affect the overall performance of the system. At the local scale, repeated and non-linear interactions...
We study the spontaneously broken phase of the XY model in three dimensions, with boundary conditions enforcing the presence of a vortex line. Comparing field theoretical and Monte Carlo determinations of the magnetization profile, we numerically determine the mass of the vortex particle in the underlying O(2)-invariant quantum field theory. The result also shows that Derrick's theorem does...
