Integrable systems represent a unique class of mathematical models in which the dynamics can be exactly solved through the existence of a sufficient number of conserved quantities. They offer a ...

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 ...

Processes in nature can often be described by equations. In many non-trivial cases, it is impossible to find the exact solutions to these equations. However, some equations are much simpler to deal ...
