Manipulating Excitation Dynamics in Structured Waveguide Quantum Electrodynamics
I Gusti Ngurah Yudi Handayana, Ya-Tang Yu, Wei-Hsuan Chung +1
Waveguide quantum electrodynamics (wQED) has become a central platform for studying collective light-matter interactions in low-dimensional photonic environments. While conventiona…
Fast and High Excitation Transport in Waveguide Quantum Electrodynamics
Ya-Tang Yu, I Gusti Ngurah Yudi Handayana, Wei Chen +1
Waveguide quantum electrodynamics (wQED) with underlying collective and long-range atom-atom interactions has led to many distinct dynamical phenomena, including modified collectiv…
Suppression of Quantum Correlations in a Clean-Disordered Atom-Nanophotonic Interface
I Gusti Ngurah Yudi Handayana, Yi-Lin Tsao, H. H. Jen
Quantum correlations are essential to the emergent behaviors of quantum systems, supporting key phenomena such as localization or delocalization of particles, quantum avalanches in…
Crossover from a delocalized to localized atomic excitation in an atom-waveguide interface
H. H. Jen, J. -S. You
An atom-waveguide system, which presents one of the quantum interfaces that enable strong couplings between light and atoms, can support tightly-confined guided modes of light. In…
Selective transport of atomic excitations in a driven chiral-coupled atomic chain
H. H. Jen
We theoretically investigate the flow of the atomic excitations in a driven chiral-coupled atomic chain with nonreciprocal decay channels. This one-dimensional system allows infini…
