Theoretical investigation of dynamics and concurrence of entangled $${{\mathcal {P}}}{{\mathcal {T}}}$$ P T and anti- $${{\mathcal {P}}}{{\mathcal {T}}}$$ P T symmetric polarized photons
Abstract Non-Hermitian systems with parity-time $$\mathcal {(PT)}$$ ( PT ) symmetry and anti-parity-time $$\mathcal {(APT)}$$ ( APT ) symmetry have exceptional points (EPs) resulting from eigenvector co-coalescence with exceptional properties. In the quantum and classical domains, higher-order EPs f...
