The "Lambda cold dark matter'' (LCDM) cosmological model is one of the great achievements in Physics of the past thirty years. Theoretical predictions formulated in the 1980s turned out to agree remarkably well with measurements, performed decades later, of the galaxy distribution and the temperature structure of the cosmic microwave background radiation. Yet, these successes do not inform us directly about the nature of the dark matter. Indeed, there are competing (and controversial) claims that the dark matter may have already been discovered, either through the annihilation of cold, or the decay of warm, dark matter particles. In astrophysics the identity of the dark matter manifests itself clearly on sub-galactic scales, including the dwarf satellite galaxies of the Milky Way and especially less massive dark matter halos, too small to have made a galaxy. I will discuss predictions from cosmological simulations assuming cold and warm (in the form of sterile neutrinos) dark matter, including for the properties of the very first halos that ever formed, and show how forthcoming astronomical observations can conclusively distinguish between the two.
The hot quark-gluon plasma, produced by heavy-ion collisions (or "Little Bangs"), is one of the most exotic states of matter. Not only is it the hottest but also the most vortical, the most magnetized, and the most ideal fluid created by humans in a laboratory. In addition, the quark-gluon plasma can reveal unusual macroscopic realizations of the chiral quantum anomaly. In this talk, I will discuss the physics and observable implications of the anomalous properties of the quark-gluon plasma, including the Chiral Separation Effect, the Chiral Magnetic Effect, and the Chiral Magnetic Wave. I will also argue that the Dirac and Weyl semimetals can host the same fundamental phenomena. They not only provide an excellent testbed for studying the anomalous properties of chiral matter but also hold great potential for technological applications.

The exotic X(3872) hadron, discovered by the Belle collaboration in 2003, has a natural width of about 1 MeV, which is unexpectedly narrow for a state with a mass very close to the D0-D0* threshold. The internal structure of the exotic meson X(3872) is still under debate. The similarity of the X(3872) mass and the D0-D* mass threshold inspired the interpretation of X(3872) as a D0-D0* mesonic molecule with small binding energy. Another explanation is that this meson is a tetraquark composed of four valence quarks.
Relativistic heavy-ion collisions produce an extremely hot and strongly interacting medium, the Quark-Gluon Plasma, which once filled the early universe at a time scale 10 microseconds after the Big-Bang. Heavy-ion collisions provide a new environment to study the nature of multi-quark states. The radii of a diluted D0-D0* mesonic molecule and a compact tetraquark are very different. The production rates in the two proposed scenarios are different in the presence of the Quark-gluon plasma. Tetraquarks and mesonic molecules interact differently with the co-moving particles. It is exciting to study X(3872) in heavy-ion collisions, which would reveal its internal structure. Studies along this line will broaden our view of the kinds of particles produced abundantly in the early universe.
