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.
