Hilbert Space Fragmentation from Generalized Symmetries
feeds.aps.org · By Thea Budde, Marina Kristć Marinković & Joao C. Pinto Barros ·
The Brief
- Hilbert space fragmentation is described as exponential growth in the number of dynamically disconnected Krylov sectors with system size.
- Fragmentation is taken as evidence of ergodicity breaking, since conventional thermalization arguments may fail.
- The paper, published in an APS journal, is by Thea Budde, Marina Kristić Marinković, and Joao C. Pinto Barros.
Why it matters
The work relates fragmentation of Hilbert space to generalized symmetries, offering a framework for understanding when quantum systems fail to thermalize, which matters for researchers studying ergodicity and many-body quantum dynamics.
