Symmetry-Enforced Non-Hermitian Jarzynski Equality in an SU(2)-Rotated Family of Hybrid $\mathcal{PT}$--$\mathcal{APT}$ Systems

Feng Zhu, Le Luo, Teng Liu, Xiaodong Tan, Zongru Yang

A parity-exchange symmetry extends the conditional Jarzynski equality from isolated PT systems to an entire SU(2)-rotated family of hybrid PT-APT Hamiltonians.

Claims

C1strongest claim

the parity-exchange symmetry persists throughout the corresponding SU(2)-rotated orbit. Relative to previous PT-focused conditional Jarzynski equality results, the advance here is an extension of the symmetry criterion from the isolated PT endpoint to a broader PT–APT hybrid family.

C2weakest assumption

the transition probabilities obey a parity-exchange symmetry (invoked in the postselected no-quantum-jump framework) and that the two-level restriction plus the specific hybrid Hamiltonian construction are representative of the broader non-Hermitian case.

C3one line summary

A parity-exchange symmetry enforces the conditional non-Hermitian Jarzynski equality throughout an SU(2)-rotated family of hybrid PT-APT two-level systems, confirmed experimentally at three points in a trapped ytterbium ion.
