Description
Quantum phase transitions and symmetry-protected topological
phases remain at the forefront of quantum physics research. This
presentation highlights recent advancements in these fields, focusing on
two key contributions:
- Realizing the Haldane Phase with Qutrits: We
discuss the successful creation of the spin-1 Haldane phase on a qudit
quantum processor, as detailed in arXiv:2408.04702. This achievement,
using trapped-ion qutrits, provides experimental evidence for topological
features like long-range string order and spin fractionalization in spin-1
chains.
- Novel Order Parameter Discovery: We explore a groundbreaking
approach for identifying quantum phase transitions in systems lacking
conventional order parameters, as presented in arXiv:2408.01400. The
reduced fidelity susceptibility (RFS) vector field is employed to
construct phase diagrams and discover new order parameters, as exemplified
in the Axial Next Nearest Neighbor Interaction (ANNNI) Model. These
studies collectively demonstrate the power of quantum processors in
simulating complex quantum systems and expanding our understanding of
quantum phases of matter.
