Description:

The physical consequences of integrability and its (weak) breaking in many body systems manifest themselves in systems such as cold atoms and conductor-insulator transitions in one dimension, as well as in specific spectral properties. It may also entail the absence of ergodicity, which in turn has deep implications on the dynamics.

The concept of integrability and its breaking is closely related to localizaton and diffusion in the Fock space of strongly disordered, interacting systems.

Finally, breaking of integrability may lead to highly non-perturbative phenomena such as the confinement of quasi-particle of topological type and decays of those with higher masses.

This workshop has explored the various incarnations and effects of integrability and its breaking in many-body, strongly interacting and disordered systems, with stimulating discussions between researchers in the various subfields.


TOPICS

- Quantum Integrable systems in low dimensionality and effects of integrability breaking
- Non-ergodicity, non-thermalization and transport in quantum integrable systems and many-body localized disordered systems
- Nonequilibrium dynamics and integrability in phenomena such as quantum quenches, many body localization in cold atoms, conductor-insulator transitions etc.
- Excitation spectra, quantum phase transitions and level statistics
