Introduction to finite-temperature field theory.Introduction to finite-temperature field theory.
In these lectures, I will given an introduction to equilibrium thermal field’ theory in the imaginary-time formalism. The need for resummation at high temperature will be discussed and I will showhow this can be achieved in an elegant way using effective field theory methods. i will also bediscussing phase transitions at finite temperature and density. A good introdoctory text can befound in [1].

Nuclear Lattice Simulations
I present four lectures that cover the theory and practice of nuclear lattice simulations using effective field theory. In the first lecture I start with the basic theory and formalism. The second lecture focuses on Monte Carlo methods and auxiliary fields. In the third lecture, I give an overview of the implementation of chiral effective field theory on the lattice. In the fourth and final lecture, I discuss the design and application of specific techniques such as the adiabatic projection method and pinhole algorithm.
Nuclear Effective Field Theories
These lectures are a pedagogical introduction to the applications of e ffective fi eld theory (EFT) in the context of nuclear physics. These applications are characterized by an interplay between nonperturbative physics (needed at leading order to produce nonrelativistic bound states and resonances) and controlled perturbative corrections (crucial for predictive power). The essential ideas are illustrated with the simplest nuclear EFT, Pionless EFT, which contains only contact interactions and, with minor changes, can be adapted to certain atomic systems. This EFT exploits the two-body unitarity limit, where renormalization leads to discrete scale invariance in systems of three and more bodies. Remarkably complex structures then arise from very simple interactions, with small corrections that can be incorporated systematically. Some of the challenges and rewards of including long-range forces --- for nuclear systems, pion exchange in Chiral EFT --- are also discussed.
Low energy nuclear physics
During the lectures I will discuss the solution of the Schroedinger equation for two nucleons considering the case of single and coupled channels. For positive energies the scattering matrix will be derived considering also the Coulomb interaction (p-p scattering). Taking in mind the extension to more complex nuclear systems. I will discuss the variational principle for bound and scattering states. In the last case, the specific form in terms of integral relations will be given. In this context I will introduce the hyperspherical harmonic basis and show some if its applications. Finally I will discuss the possibility of observing universal properties low energy nuclear physics.
Dense Matter and Compact Stars
In a set of four lectures, I am going to review how we built our understanding of dense matter in the past decades. This includes, in additional to experiments performed in labs, observational data from white dwarfs, neutron stars, supernova explosions and, more recently, gravitational waves from neutron star mergers. I am going to present a few simple models used in the past to describe dense matter, describe what features must be included in modern descriptions of dense matter and, finally, discuss some open questions and challenges of the field.

Origin of the Proton Mass and Nuclear-Bound Quarkonium
ILow-energy interactions of heavy quarkonia with nucleons offer the opportunity to learn about the mass distribution inside a nucleon. The quarkonium-nucleon scattering amplitude at threshold is proportional to the matrix element of gluon fields inside the nucleon, which, in turn, due to the QCD the trace anomaly gives the proton mass. The scattering amplitude becomes enhanced when the quarkonium is in the interior of an atomic nucleus, because there is a constructive superposition of the contributions from all the nucleons of the nucleus. In this talk I will discuss recent developments in this subject, focusing on the use of effective field theory (EFT) techniques to extrapolate to the physical point quarkonium-nucleon interactions obtained in lattice QCD simulations performed with large pion masses. I will then present predictions based on the extrapolated interactions for nuclear-bound quarkonium states and relate them to upcoming experiments.
