Induced transparency: interference or polarization?
Changqing Wang, Xuefeng Jiang, William R. Sweeney +8
The polarization of optical fields is a crucial degree of freedom in the all-optical analogue of electromagnetically induced transparency (EIT). However, the physical origins of EI…
Cavity piezo-mechanics for superconducting-nanophotonic quantum interface
Xu Han, Wei Fu, Changchun Zhong +8
Hybrid quantum systems are essential for the realization of distributed quantum networks. In particular, piezo-mechanics operating at typical superconducting qubit frequencies feat…
Electromagnetically induced transparency at a chiral exceptional point
Changqing Wang, Xuefeng Jiang, Guangming Zhao +6
Electromagnetically induced transparency, as a quantum interference effect to eliminate optical absorption in an opaque medium, has found extensive applications in slow light gener…
Parity-time symmetry in optical microcavity systems
Jianming Wen, Xiaoshun Jiang, Liang Jiang +1
Canonical quantum mechanics postulates Hermitian Hamiltonians to ensure real eigenvalues. Counterintuitively, a non-Hermitian Hamiltonian, satisfying combined parity-time (PT) symm…
