Free fermions beyond Jordan and Wigner

One dimensional chains of free fermions belong to the simplest many body
systems, where many physical quantities can be computed with ease. In
quantum information theory free fermionic circuits are also distinguished:
they lead to classical simulability of quantum states. Recently a new class
of models was discovered[1,2], which have a hidden free fermionic
structure, despite being apparently interacting. The hidden free fermions
are obtained with a construction that is distinct from the well known
Jordan-Wigner transformation. We review the progress in this topic,
focusing on selected models and their properties.
