Parent Hamiltonian and intrinsic phase transition in non-Hermitian photonic systems

arXiv:2607.28964v1 Announce Type: new Abstract: Non-Hermitian systems host phenomena absent in Hermitian physics, but realizing Hamiltonians with intrinsic non-Hermitian properties remains challenging. The theoretical method of non-Hermitian parent Hamiltonian (NH-PH) enables the construction of a
