Integrable systems and Hamiltonian dynamics occupy a central role in modern theoretical physics and mathematics. At their heart, these systems are characterised by the existence of a sufficient number ...

Universal characters, a natural generalisation of the classical Schur functions, have emerged as a powerful algebraic tool in the study of integrable systems. They are defined as polynomials attached ...

Thermalization in classical systems can be well-understood by ergodicity. While ergodicity is absent for quantum systems, it is generally believed that the non-integrable quantum systems should ...
