Chiral Quantum Dynamics Without Encircling Exceptional Points

Researchers in the journal Light: Science & Applications demonstrated chiral behavior in a quantum system without encircling its Liouvillian exceptional points (LEPs). Using a Paul-trapped ion setup, they showed asymmetric mode conversion crucial for quantum thermodynamic cycles, highlighting the role of non-adiabatic processes like the Landau-Zener-Stückelberg phase in chiral state transfer dynamics.
