Abstract
We introduce the so-called dual unitary circuits. They are exactly solvable dynamical systems, which are defined on a 1+1 dimensional discrete space time. The defining property of the systems is that they have unitary time evolution, therefore they are good quantum mechanical models, and they also have a unitary evolution operator which translates them along the space direction. These unique properties make them exactly solvable. The models can show integrable and chaotic behaviour as well. In the chaotic cases they present one of the few exactly solvable models, where correlation functions can be computed.
