The structure of rotating quantum systems is fundamentally determined by how these systems carry angular momentum. A priori very different systems share some basic properties that appear universal. Examples are the reduced dimensionality due to rotation and formation of vortices, as well as composites of particles and vortices. These phenomena may occur both in bosonic and fermionic systems and regardless of the form of the interparticle potential. Due to this universality, rotating quantum liquids can be described theoretically by using similar concepts and analogous vocabulary.
Our review work aims to give a unified view of the progress in the fields of finite rotating quantum systems, setting the emphasis on the structural properties of the many-body state. The focus will be on the theoretical results and development of many-body techniques used in this context. We highlight the similarities between rotating bosonic and fermionic systems, taking the analogy between electronic states in quantum dots, and bosonic states in rotating Bose-Einstein condensates as a recurring example.
