Multiple mobility rings in non-Hermitian Su-Schrieffer-Heeger chain with quasiperiodic potentials

Key Points

• Mobility rings appear in non-Hermitian regimes, offering insights into topological phases.
• Key findings indicate multiple mobility rings can exist due to quasiperiodic potentials, suggesting intricate behavior.
• Analysis of a theoretical model shows that these rings stem from unique interference patterns in the chain.
• Implications for practical applications in quantum materials and advanced photonic devices must be explored further.
