Quantum World in a Liquid Dr. Anton Vorontsov, MSU Physics I will give a basic introduction to the field of condensed-matter physics, its current achievements and research directions. In particular I will talk about such quantum states as Superconductivity and Superfluidity where one can see Quantum World without a microscope. These states provide a fundamental example of condensed phase of matter, where quantum particles interact and become strongly correlated. Such states exist in various physical realities, from ultra cold atoms in Earth laboratories to neutron stars in galaxies far far away. And the best part, we all still have a chance to find something new there!
