12:20 - 13:00
Anomaly-induced transport phenomena in presence of strong external electromagnetic fields are explored within a 4D field theory defined holographically as U(1)V×U(1)A Maxwell-Chern-Simons theory in Schwarzschild-AdS5. Two complementary studies are reported. In the first one, we present results on the Ohmic conductivity, diffusion constant, chiral magnetic conductivity, and additional anomaly-induced transport coefficients as functions of external e/m fields. Next, gradient resummation in a constant background magnetic field is performed. All-order resummed constitutive relations are parameterised by four momenta-dependent transport coefficient functions (TCFs). A highlight of this part is a thorough study of {\it non-dissipative} chiral magnetic waves (CMW) in strong magnetic fields. (reference-doi: 10.1007/JHEP05(2019)071)

An approach to QCD vacuum as a medium describable in terms of statistical ensemble of almost everywhere homogeneous Abelian (anti-)self-dual gluon field is briefly reviewed. These fields can be seen as the confining medium for color charged fields as well as underline the specific realization of chiral $SU_{\rm L}(N_f)\times SU_{\rm R}(N_f)$ and $U_A(1)$ symmetries. The long-range fluctuations of topological charge density play important role both for confinement and chiral symmetry breaking. Hadronization formalism based on this ensemble leads to manifestly defined quantum effective action for colorless hadrons. Strong, electromagnetic and weak interactions of mesons are represented in the action in terms of nonlocal $n$-point interaction vertices given by the quark-gluon loops averaged over the background ensemble. Systematic results for the mass spectrum and decay constants of radially excited light, heavy-light mesons and heavy quarkonia as well as electromagnetic form factors are presented. Interrelations between the present mean field type approach and the results of functional renormalization group and DSE results are discussed. Peculiarities of the approach in description of deconfinement and chiral symmetry restoration under extreme conditions (strong electromagnetic fields, high energy and baryon densities) are outlined.

16:20 - 17:00
The kurtosis and skewness of net baryon-number fluctuations are studied for the magnetized phase diagram of three-flavor quark matter within the Polyakov extended Nambu–Jona-Lasinio model. The effect of magnetic catalysis and inverse magnetic catalysis is considered using two distinct scalar interactions. Special attention is given to the fluctuations dependence near the critical end points (CEPs). Regions with large fluctuations but no CEP in non-magnetized matter develop a CEP under the action of a strong magnetic field.

16:20 - 17:00
There are currently no first-principle calculations for QCD at large, but not asymptotically large, baryon densities. For instance, we do not know at which densities there is a transition from nuclear matter to deconfined quark matter and what the nature of this transition is. I will discuss a holographic approach, using the Sakai-Sugimoto model, in which nuclear matter and quark matter are treated consistently on the same footing. In particular, baryons are described as instantons in the bulk and I will explain an approximation that takes into account instanton interactions. The results show that nuclear and quark matter can be connected continuously, and thus the model can be used to study a potential quark-hadron continuity at densities relevant for the cores of neutron stars.

I will review several aspects of the QCD phase diagram, paying special attention to the interplay between chiral and $U(1)_A$ restoration, exploring partner degeneration and patterns of symmetry breaking. I will show that the use of Ward Identities (WI) allows to shed light on this issue, being also a fruitful tool for the understanding of thermal observables. In addition, effective chiral lagrangians provide a model-independent realization of these ideas. In fact, a simple meson gas description might be already a good approximation for certain observables. Thus, Chiral Perturbation Theory (ChPT) scattering amplitudes combined with unitarization generate a thermal $f_0(500)$ state which saturates the scalar susceptibility in accordance with the lattice. On the other hand, a $U(3)$ ChPT-based analysis of the topological susceptibility reveals interesting aspects of the role of the $\eta'$ state and the connection with chiral and $U_A(1)$ restoration through WI.
