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 ...

Integrable Hamiltonian systems, characterised by the existence of a complete set of conserved quantities, form a central class of models in mathematical physics. Such systems are distinguished by ...

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 ...
