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…
Photonic Metamaterial Analogue of a Continuous Time Crystal
Tongjun Liu, Jun-Yu Ou, Kevin F. MacDonald +1
Time crystals are an eagerly sought phase of matter with broken time-translation symmetry. Quantum time crystals with discretely broken time-translation symmetry have been demonstr…
Observation of pi/2 modes in an acoustic Floquet system
Zheyu Cheng, Raditya Weda Bomantara, Haoran Xue +3
Topological phases of matter have remained an active area of research in the last few decades. Periodic driving is known to be a powerful tool for enriching such exotic phases, whi…
Experimental demonstration of Quantum Overlapping Tomography
Yang Zhengning, Shihao Ru, Lianzhen Cao +2
Quantum tomography is one of the major challenges of large-scale quantum information research due to the exponential time complexity. In this work, we develop and apply a Bayesian…
Perovskite quantum dot topological laser
Jingyi Tian, Qi Ying Tan, Yutao Wang +4
Various topological laser concepts have recently enabled the demonstration of robust light-emitting devices that are immune to structural deformations and tolerant to fabrication i…
Ballistic Dynamics of Flexural Thermal Movements in a Nano-membrane Revealed with Subatomic Resolution
Tongjun Liu, Jun-Yu Ou, Nikitas Papasimakis +3
Flexural oscillations of free-standing films, nano-membranes and nano-wires are attracting growing attention for their importance to the thermal, electrical and mechanical properti…
Toroidal optical transitions in hydrogen-like atoms
Ilya Kuprov, David Wilkowski, Nikolay Zheludev
It is commonly believed that electromagnetic spectra of atoms and molecules can be fully described by interactions of electric and magnetic multipoles. However, it has recently bec…
Anomalous Floquet non-Hermitian skin effect in a ring resonator lattice
He Gao, Haoran Xue, Zhongming Gu +6
We present a one-dimensional coupled ring resonator lattice exhibiting a variant of the non- Hermitian skin effect (NHSE) that we call the anomalous Floquet NHSE. Unlike existing a…
