The lectures address a big question: what is the interplay of quantum matter, as described by quantum field theory, and spacetime geometry. This is done with a focus on situations that can be created and investigated in modern physics laboratories, like ultra-cold quantum gases, quantum fluids, condensed matter systems like graphene, or photonic crystals. It will be shown how quantum field theory in curved spacetime starts to play a role when material properties like the velocity of sound, fluid velocity, Fermi velocity, lattice properties, or an energy gap become functions of space and time. Quantum field theory in curved spacetime will be introduced, together with some applications in the early universe or in the vicinity of black holes. Also some of its most interesting consequences, a refinement of the concepts of particles, will be discussed in some detail, from a theoretical perspective, as well as in terms of experimental results.
