Nonzero baryon density QCD lattice simulations suffer from the well known sign problem, which has so far prevented the exploration of the QCD phase diagram. In this talk we discuss our results on the phase diagram of the 3d O(4) model. This model is an effective theory of QCD with two flavors in the chiral limit, which can be simulated at nonzero baryon density without sign problem. In this model

Using the linear sigma model coupled to quarks, we discuss the influence of an external magnetic field on the QCD phase diagram in the temperature vs.chemical potential plane. Provided the plasma screening is properly accounted, we show that the critical temperature for the phase transition, chiral symmetry restoration, decrease with increasing magnetic field (inverse magnetic catalysis). The loca

The location of the ---up to now hypothetical--- critical end point and the exploration of the QCD phase diagram are important challenges both theoretically and experimentally. With two massless quark flavors the QCD Lagrangian has a $SU(2)_L\otimes SU(2)_R \simeq O(4)$ symmetry. This Lagrangian is the same as the four component Heisenberg ferromagnet which we use as an effective model. With degen

QCD at high chemical potential has interesting properties such as diquark condensation and deconfinement of quarks. Two-colour QCD, which enables numerical simulations on the lattice, constitutes a laboratory to study QCD at high chemical potential.
We studied two colour QCD at high density, using the Nambu-Gorkov formalism, which puts the quarks and antiquarks into a single spinor. We examine

The Schwinger model represents Quantum Electrodynamics in 2
space-time dimensions ($2d$ QED). It shares key properties with $4d$
QCD, in particular confinement and topology. We present preliminary
simulations results of its lattice formulation with $N_f$=2 degenerate
fermion flavors, which are represented as Wilson fermions, in
anisotropic volumes. At any $N_f$>1 the chiral condensate vanishe

We review, from a theoretical and phenomenological point of view, different frameworks that are commonly used in literature to explore the traits of the QCD phase diagram, including lattice simulations, field theoretical methods and effective models of strong interactions. We particularly present some features of the physical observables that might be helpful to pin-point the position of the Criti

With the arrival of a new generation of experiments that will allow us to
probe QCD at densities and temperatures closer to the CEP, it is more important than ever to extract insights from the complex theory of QCD. Given
this complexity, physicist has resorted to diverse direct and indirect methods
to extract predictions from the theory, among those methods are: pQCD for high energy interactio
