    Many-body Entanglement and Tensor Networks: an Introduction 1h
    
    Quantum systems, such as lattices of quantum spins, are very hard to study because the associated many-body Hilbert space is simply huge: its dimension grows exponentially with the size of the lattice. As a result, not even the most powerful supercomputer on Earth is large enough to deal with the many-body state of, say, 60 quantum spins. In recent years, however, progress in our understanding of quantum entanglement has revealed that only a small region of this huge Hilbert space is actually relevant to the study of quantum many-body systems. Using tensor networks, we have then been able to efficiently describe some of the states in this small, physically relevant region of the many-body Hilbert space. In this talk, directed to non-experts, I will (i) review our current understanding of many-body entanglement, (ii) introduce tensor networks as an efficient description of many-body states, and (iii) mention some of its current applications, which nowadays includes quantum gravity, statistical physics and machine learning.

    SO(3) "Nuclear Physics" with ultracold Gases 1h
    
    An ab initio calculation of nuclear physics from Quantum Chromodynamics (QCD), the fundamental SU(3) gauge theory of the strong interaction, remains an outstanding challenge. Here, we discuss the emergence of key elements of nuclear physics using an SO(3) lattice gauge theory as a toy model for QCD. We show that this model is accessible to state-of-the-art quantum simulation experiments with ultracold atoms in an optical lattice. First, we demonstrate that our model shares characteristic many-body features with QCD, such as the spontaneous breakdown of chiral symmetry, its restoration at finite baryon density, as well as the existence of few-body bound states. Then we show that in the one-dimensional case, the dynamics in the gauge invariant sector can be encoded as a spin S=3/2 Heisenberg model, i.e., as quantum magnetism, which has a natural realization with bosonic mixtures in optical lattices, and thus sheds light on the connection between non-Abelian gauge theories and quantum magnetism.
