Non-Hermitian Photonic Lattices: tutorial
Qiang Wang, Y. D. Chong
Non-Hermitian photonic lattices combine the peculiar consequences of energy non-conservation with the physics of bandstructures, giving rise to a variety of exotic properties not f…
Bulk-plasmon-mediated free-electron radiation beyond the conventional formation time
Fuyang Tay, Xiao Lin, Xihang Shi +3
Free-electron radiation is a fundamental photon emission process that is induced by fast-moving electrons interacting with optical media. Historically, it has been understood that,…
Topological Transitions with an Imaginary Aubry-Andre-Harper Potential
Bofeng Zhu, Li-Jun Lang, Qiang Wang +2
We study one-dimensional lattices with imaginary-valued Aubry-Andre-Harper (AAH) potentials. Such lattices can host edge states with purely imaginary eigenenergies, which differ fr…
Single atom in a superoscillatory optical trap
Hamim Mahmud Rivy, Syed A. Aljunid, Emmanuel Lassalle +2
Optical tweezers have become essential tools to manipulate atoms or molecules at a single particle level. However, using standard diffracted-limited optical systems, the transverse…
Photon number resolution without optical mode multiplication
Anton N. Vetlugin, Filippo Martinelli, Shuyu Dong +1
Common methods to achieve photon number resolution rely on fast on-off single-photon detectors in conjunction with temporal or spatial mode multiplexing. Yet, these methods suffer…
Continuum of Bound States in a Non-Hermitian Model
Qiang Wang, Changyan Zhu, Xu Zheng +3
In a Hermitian system, bound states must have quantized energies, whereas extended states can form a continuum. We demonstrate how this principle fails for non-Hermitian systems, b…
