Photonic band structure design using persistent homology
Daniel Leykam, Dimitris G Angelakis
The machine learning technique of persistent homology classifies complex systems or datasets by computing their topological features over a range of characteristic scales. There is…
Quantum transient heat transport in the hyper-parametric oscillator
JungYun Han, Daniel Leykam, Dimitris G. Angelakis +1
We explore nonequilibrium quantum heat transport in nonlinear bosonic systems in the presence of a non-Kerr-type interaction governed by hyper-parametric oscillation due to two-pho…
Probing band topology using modulational instability
Daniel Leykam, Ekaterina Smolina, Aleksandra Maluckov +2
We analyze the modulational instability of nonlinear Bloch waves in topological photonic lattices. In the initial phase of the instability development captured by the linear stabil…
Topological phases in ring resonators: recent progress and future prospects
Daniel Leykam, Luqi Yuan
Topological photonics has emerged as a novel paradigm for the design of electromagnetic systems from microwaves to nanophotonics. Studies to date have largely focused on the demons…
Disorder-Protected Quantum State Transmission through Helical Coupled-Resonator Waveguides
JungYun Han, Andrey A. Sukhorukov, Daniel Leykam
We predict the preservation of temporal indistinguishability of photons propagating through helical coupled-resonator optical waveguides (H-CROWs). H-CROWs exhibit a pseudospin-mom…
Nontrivial coupling of light into a defect: the interplay of nonlinearity and topology
Shiqi Xia, Dario Jukić, Nan Wang +9
The flourishing of topological photonics in the last decade was achieved mainly due to developments in linear topological photonic structures. However, when nonlinearity is introdu…
Probing bulk topological invariants using leaky photonic lattices
Daniel Leykam, Daria A. Smirnova
Topological invariants characterising filled Bloch bands attract enormous interest, underpinning electronic topological insulators and analogous artificial lattices for Bose-Einste…
Edge mode bifurcations of two-dimensional topological lasers
Sinan Gundogdu, Juzar Thingna, Daniel Leykam
Topological lasers are of growing interest as a way to achieve disorder-robust single mode lasing using arrays of coupled resonators. We study lasing in a two-dimensional coupled r…
Edge modes in 2D electromagnetic slab waveguides: analogues of acoustic plasmons
Daniel Leykam, Konstantin Y. Bliokh, Franco Nori
We analyze planar electromagnetic waves confined by a slab waveguide formed by two perfect electrical conductors. Remarkably, 2D Maxwell equations describing transverse electromagn…
