Effective field theory is a great tool to study emergent and macroscopic behaviour in condensed matter physics. Especially exciting is their application to exotic states of matter, which are characterized by unusual properties such as spin-charge separation, charge fractionalization or immobile excitations. This often leads to interesting field theories. Examples include topological theories (Θ-term, Chern-Simons) and higher order gauge theories. The main goal of this talk is to present these fascinating phenomena and explain how they can be described by field theories.
