Interference-Protected Subradiance and Bound States in Nested Atomic Arrays
Bella Santosa, Daniel Leykam
Collective subradiant states in waveguide QED are highly sensitive to disorder, limiting their scalability and robustness. We propose a deterministic approach to engineering atom a…
Quantum Metamorphosis: Programmable Emergence and the Breakdown of Bulk-Edge Dichotomy in Multiscale Systems
Mahmoud Jalali Mehrabad, Alireza Parhizkar, Lida Xu +6
Multiscale synergy -- the interplay of a system's distinct characteristic length, time, and energy scales -- is becoming a unifying thread across many contemporary branches of scie…
Mie-tronics supermodes and symmetry breaking in nonlocal metasurfaces
Thanh Xuan Hoang, Ayan Nussupbekov, Jie Ji +3
It is usually believed that symmetry breaking in photonic systems leads to weaker optical confinement, such as in the case of metasurfaces when bound states in the continuum are re…
Unconventional localization of light with Mie-tronics
Thanh Xuan Hoang, Daniel Leykam, Ayan Nussupbekov +3
Localization of light requires high-Q cavities or spatial disorder, yet the wave nature of light may open novel opportunities. Here we suggest to employ Mie-tronics as a powerful a…
Bulk-hole correspondence and inner robust boundary modes in singular flatband lattices
Limin Song, Shenyi Gao, Shiqi Xia +5
Topological entities based on bulk-boundary correspondence are ubiquitous, from conventional to higher-order topological insulators, where the protected states are typically locali…
Collective nature of high-Q resonances in finite-size photonic metastructures
Thanh Xuan Hoang, Daniel Leykam, Hong-Son Chu +3
We study high quality-factor (high Q) resonances supported by periodic arrays of Mie resonators from the perspectives of both Bloch wave theory and multiple scattering theory. We r…
Flat band fine-tuning and its photonic applications
Carlo Danieli, Alexei Andreanov, Daniel Leykam +1
Flat bands - single-particle energy bands - in tight-binding networks have attracted attention due to the presence of macroscopic degeneracies and their extreme sensitivity to pert…
Nonlinear compact localized modes in flux-dressed octagonal-diamond photonic lattice
M. G. Stojanovic, S. Gundogdu, D. Leykam +4
Tuning the values of artificial flux in the two-dimensional octagonal-diamond lattice drives topological phase transitions, including between singular and non-singular flatbands. W…
